错误消息 SyntaxError：当您尝试使用Python 3语法与Python 2 Print语句时，会在“ print” 呼叫中丢失括号。

示例：
>

print "Hello, World!"

在Python 3中，打印语句被print（）函数替换，需要围绕要打印的值括号。

解决方案

print("Hello, World!")

在Python 3中，打印语句被打印（）函数代替，需要围绕要打印的值括号。

>>> print("Hello, World!")
Hello, World!

在Python 3的早期版本中，解释器只是报告了通用语法错误，而没有提供任何可能出现的有用提示：

>>> print "Hello, World!"
  File "<stdin>", line 1
    print "Hello, World!"
                        ^
SyntaxError: invalid syntax

而对于，为什么为什么在Python 3中的功能与语句的基本形式无关，而是与您如何做更复杂的事情，例如用后续空间打印多个项目，而不是结束行。

在Python 2中：

>>> import sys
>>> print >> sys.stderr, 1, 2, 3,; print >> sys.stderr, 4, 5, 6
1 2 3 4 5 6

在Python 3中：

>>> import sys
>>> print(1, 2, 3, file=sys.stderr, end=" "); print(4, 5, 6, file=sys.stderr)
1 2 3 4 5 6

从2017年9月的Python 3.6.3发行开始，已经更新了与Python 2.x 2.x打印语法相关的一些错误消息，以推荐其Python 3.x 3.x对应物：

>>> print "Hello!"
  File "<stdin>", line 1
    print "Hello!"
                 ^
SyntaxError: Missing parentheses in call to 'print'. Did you mean print("Hello!")?

自从“自“自从”呼叫打印“ case是一个编译时间语法错误，因此可以访问原始源代码，它可以在建议的其余部分中包含全文 替代品。但是，目前尚未尝试制定适当的报价来围绕该表达式放置（这不是不可能的，只是足够复杂，以至于尚未完成）。

typeError为正确的换档运算符筹集的也已被定制：

>>> print >> sys.stderr
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unsupported operand type(s) for >>: 'builtin_function_or_method' and '_io.TextIOWrapper'. Did you mean "print(<message>, file=<output_stream>)"?

由于代码运行时会增加此错误，而不是在编译时，它无法访问原始源代码，并且因此，在建议的替换表达式中使用meta-variobles（＆lt; message＆gt; and ＆lt; output_stream＆gt; ）打字。与语法错误案例不同，在自定义右移动错误消息中围绕Python表达式的引号很简单。

The error message SyntaxError: Missing parentheses in call to 'print' occurs when you attempt to use Python 3 syntax with the Python 2 print statement.

Example:

print "Hello, World!"

In Python 3, the print statement was replaced with a print() function, requiring parentheses around the value to be printed.

Solution

print("Hello, World!")

In Python 3, the print statement was replaced with a print() function, requiring parentheses around the value to be printed.

>>> print("Hello, World!")
Hello, World!

In earlier versions of Python 3, the interpreter just reports a generic syntax error, without providing any useful hints as to what might be going wrong:

>>> print "Hello, World!"
  File "<stdin>", line 1
    print "Hello, World!"
                        ^
SyntaxError: invalid syntax

As for why print became an ordinary function in Python 3, that didn't relate to the basic form of the statement, but rather to how you did more complicated things like printing multiple items to stderr with a trailing space rather than ending the line.

In Python 2:

>>> import sys
>>> print >> sys.stderr, 1, 2, 3,; print >> sys.stderr, 4, 5, 6
1 2 3 4 5 6

In Python 3:

>>> import sys
>>> print(1, 2, 3, file=sys.stderr, end=" "); print(4, 5, 6, file=sys.stderr)
1 2 3 4 5 6

Starting with the Python 3.6.3 release in September 2017, some error messages related to the Python 2.x print syntax have been updated to recommend their Python 3.x counterparts:

>>> print "Hello!"
  File "<stdin>", line 1
    print "Hello!"
                 ^
SyntaxError: Missing parentheses in call to 'print'. Did you mean print("Hello!")?

Since the "Missing parentheses in call to print" case is a compile time syntax error and hence has access to the raw source code, it's able to include the full text on the rest of the line in the suggested replacement. However, it doesn't currently try to work out the appropriate quotes to place around that expression (that's not impossible, just sufficiently complicated that it hasn't been done).

The TypeError raised for the right shift operator has also been customised:

>>> print >> sys.stderr
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unsupported operand type(s) for >>: 'builtin_function_or_method' and '_io.TextIOWrapper'. Did you mean "print(<message>, file=<output_stream>)"?

Since this error is raised when the code runs, rather than when it is compiled, it doesn't have access to the raw source code, and hence uses meta-variables (<message> and <output_stream>) in the suggested replacement expression instead of whatever the user actually typed. Unlike the syntax error case, it's straightforward to place quotes around the Python expression in the custom right shift error message.

“语法”是什么：在呼叫到“ print”中缺少括号。在python中的意思？

您可以使用语义令牌设置背景和文本颜色：
“ Chakra-Body-Text”和“ Chakra-Body-BG”，其各自的_light和
_DARK键。

您可以在此处看到此操作（并切换主题）：
https://codesandbox.io/s/s/chakra-chakra-chakra-ui-theme-bg--bg--bg-- ty5qt0

我找不到记录的特定问题，但这里有相关链接：

import * as React from "react";
import * as ReactDOMClient from "react-dom/client";
import { ChakraProvider, extendTheme } from "@chakra-ui/react";
import App from "./App";

const theme = extendTheme({
  semanticTokens: {
    colors: {
      "chakra-body-text": {
        _light: "purple.800",
        _dark: "pink.100",
      },
      "chakra-body-bg": {
        _light: "pink.100",
        _dark: "purple.800",
      },
    },
  },
});

const rootElement = document.getElementById("root");
const root = ReactDOMClient.createRoot(rootElement);

root.render(
  <ChakraProvider theme={theme}>
    <App />
  </ChakraProvider>
);

You can set the background and text colour using the semantic tokens:
"chakra-body-text" and "chakra-body-bg", with their respective _light and
_dark keys.

You can see this in action (and toggle the theme) here:
https://codesandbox.io/s/chakra-ui-theme-bg-ty5qt0

I couldn't find this specific issue documented, but here are related links:

import * as React from "react";
import * as ReactDOMClient from "react-dom/client";
import { ChakraProvider, extendTheme } from "@chakra-ui/react";
import App from "./App";

const theme = extendTheme({
  semanticTokens: {
    colors: {
      "chakra-body-text": {
        _light: "purple.800",
        _dark: "pink.100",
      },
      "chakra-body-bg": {
        _light: "pink.100",
        _dark: "purple.800",
      },
    },
  },
});

const rootElement = document.getElementById("root");
const root = ReactDOMClient.createRoot(rootElement);

root.render(
  <ChakraProvider theme={theme}>
    <App />
  </ChakraProvider>
);

您可以使用Chakra-ui的菌落将背景颜色更改为任何颜色，还是仅适用于轻度和深色模式？

您应该创建一个以给定字母开头的所有单词的数组，而不是将单词设置为值。

这是一个工作代码：

function sortToMap(str) {
   const words = str.toLowerCase().split(" ")
   // no need for map in JS, an object will work fine
   const map = {}
   for(let word of words) {
      const key = word[0]
      if(!(key in map))
         map[key] = []
      map[key].push(word)
   }
   
   return map
}

let myString = "Test string to check How it Works and hopefully it is fine";
console.log(sortToMap(myString));

Instead of setting the word as the value, you should create an array that stores all the words starting with a given letter.

Here is a working code :

function sortToMap(str) {
   const words = str.toLowerCase().split(" ")
   // no need for map in JS, an object will work fine
   const map = {}
   for(let word of words) {
      const key = word[0]
      if(!(key in map))
         map[key] = []
      map[key].push(word)
   }
   
   return map
}

let myString = "Test string to check How it Works and hopefully it is fine";
console.log(sortToMap(myString));

将所有与标准匹配到地图的单词

所需元素是动态元素，因此要单击您需要诱导的元素 webdriverwait href =“ https://stackoverflow.com/a/54194511/7429447”> emeltage_be_be_clickable（） ，您可以使用以下任何一个 定位器策略 ：

  • 使用 css_selector ：

      webdriverwait（驱动程序，20）.ultil（ec.element_to_be_be_clickable（（（by.css_selector），“ button [class*='button'button']＆gt; div [class^='contents']”））。点击（）

  • 使用 xpath ：

      webdriverwait（驱动程序，20）.until（ec.element_to_be_be_clickable（（（by.xpath，“ // button/div） ']“）））。点​​击（）

  • 注意：您必须添加以下导入：

     来自selenium.webdriver.support.ui导入webdriverwait
从selenium.webdriver.common.通过进口
从selenium.webdriver.support进口预期_conditions作为ec

The desired element is a dynamic element, so to click on the element you need to induce WebDriverWait for the element_to_be_clickable() and you can use either of the following locator strategies:

  • Using CSS_SELECTOR:

    WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "button[class*='button'] > div[class^='contents']"))).click()

  • Using XPATH:

    WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//button/div[starts-with(@class, 'contents') and text()='Accept Invite']"))).click()

  • Note: You have to add the following imports :

    from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC

我个人使用一个名为selenium-wire 可用于身份验证和未经认证的代理。这是代理使用的文档参考 https：//github.com/wkeeling/wkeeling/selenium-wire#代理

我制作了一个简短的代码段，使用公共代理到Google.com，

import seleniumwire
from seleniumwire import webdriver

options = {'proxy': 
{
    'http' : 'http://45.152.188.246:3128'}
}

driver = webdriver.Chrome(seleniumwire_options=options)

driver.get("https://google.com/")

这也是一种方法无需硒即可而无需使用。

options = webdriver.ChromeOptions()
options.add_argument('--proxy-server=45.152.188.246:3128')

driver = webdriver.Chrome(options=options)

driver.get("https://google.com/")

Personally, I use a library called selenium-wire https://pypi.org/project/selenium-wire/ which can be used for both authenticated and non-authenticated proxies. Here is the documentation reference for proxy use https://github.com/wkeeling/selenium-wire#proxies

I have made a short snippet of code that uses a public proxy to go to google.com

import seleniumwire
from seleniumwire import webdriver

options = {'proxy': 
{
    'http' : 'http://45.152.188.246:3128'}
}

driver = webdriver.Chrome(seleniumwire_options=options)

driver.get("https://google.com/")

Here is also a method that would work without the need for selenium-wire.

options = webdriver.ChromeOptions()
options.add_argument('--proxy-server=45.152.188.246:3128')

driver = webdriver.Chrome(options=options)

driver.get("https://google.com/")

Selenium-将HTTP代理设置为WebDriver

我认为您必须在AddPostFrameCallback中调用SetState（）函数，此功能将在构建过程完成后返回回调。
可能是您的工作。

还要检查文档：

WidgetsBinding.instance!.addPostFrameCallback((_) {
      setState(() {
        questionIndex = questionIndex + 1;
      });
    });

I think you have to call setState() function inside addPostFrameCallback, this function will return callback when the build process is finished.
Might be it's work's for you.

Also check doc: addPostFrameCallback

WidgetsBinding.instance!.addPostFrameCallback((_) {
      setState(() {
        questionIndex = questionIndex + 1;
      });
    });

setState（）函数在小部件构建过程中被调用，尽管我已经通过了一个指针，但是它没有识别它

避免名称相撞的规则都在C ++标准中（请参阅Stroustrup Book），并由C ++ Gurus（Sutter等）提到。

个人规则

是因为我不想处理案件，并且想要一个简单的规则，所以我设计了一个简单而正确的个人：


命名符号时，如果您：，您将避免与编译器/OS/标准库发生碰撞：

  • 永远不会启动使用下划线的符号

  • 切勿在内部有两个连续下强调的符号命名。

当然，将您的代码放在唯一的名称空间中也有助于避免碰撞（但不会防止邪恶的宏）

一些示例

（我使用宏，因为它们是C/C ++符号的更高代码污染，但这可能是从变量名到class名称的任何内容）

#define _WRONG
#define __WRONG_AGAIN
#define RIGHT_
#define WRONG__WRONG
#define RIGHT_RIGHT
#define RIGHT_x_RIGHT

从

n3242.pdf 文件（我希望最终的标准文本相似）：

17.6.3.3.2全局名称[global.names]

某些名称和功能签名始终保留到实现：

- 每个包含双重下划线_ _或以下划线开始的名称，然后将大写字母（2.12）保留给实现。

- 以下划线开头的每个名称都保留到实现中，以用作全局名称空间中的名称。

但是也：

17.6.3.3.5用户定义的文字后缀[usrlit.suffix]

不以下划线开头的文字后缀标识符保留用于将来的标准化。

最后一个子句令人困惑，除非您考虑一个以一个下划线开头的名称，然后再说一个小写字母，如果在全球名称空间中定义了 not> not>

The rules to avoid collision of names are both in the C++ standard (see Stroustrup book) and mentioned by C++ gurus (Sutter, etc.).

Personal rule

Because I did not want to deal with cases, and wanted a simple rule, I have designed a personal one that is both simple and correct:


When naming a symbol, you will avoid collision with compiler/OS/standard libraries if you:

  • never start a symbol with an underscore
  • never name a symbol with two consecutive underscores inside.

Of course, putting your code in an unique namespace helps to avoid collision, too (but won't protect against evil macros)

Some examples

(I use macros because they are the more code-polluting of C/C++ symbols, but it could be anything from variable name to class name)

#define _WRONG
#define __WRONG_AGAIN
#define RIGHT_
#define WRONG__WRONG
#define RIGHT_RIGHT
#define RIGHT_x_RIGHT

Extracts from C++0x draft

From the n3242.pdf file (I expect the final standard text to be similar):

17.6.3.3.2 Global names [global.names]

Certain sets of names and function signatures are always reserved to the implementation:

— Each name that contains a double underscore _ _ or begins with an underscore followed by an uppercase letter (2.12) is reserved to the implementation for any use.

— Each name that begins with an underscore is reserved to the implementation for use as a name in the global namespace.

But also:

17.6.3.3.5 User-defined literal suffixes [usrlit.suffix]

Literal suffix identifiers that do not start with an underscore are reserved for future standardization.

This last clause is confusing, unless you consider that a name starting with one underscore and followed by a lowercase letter would be Ok if not defined in the global namespace...

在C＆＃x2b;＆＃x2B中使用下划线的规则是什么。标识符？

    ;

You can roll it by hand easily enough:
https://godbolt.org/z/xcGz6657r although it's probably better to use a coroutine generator if you have one available.

You can return an optional in the generator, and stop taking elements when a std::nullopt is generated with views::take_while

auto out = ranges::views::generate(
    [i = 0]() mutable -> std::optional<int>
    {
        if (i > 3)
            return std::nullopt;

        return { i++ };
    })
    | ranges::views::take_while([](auto opt){ return opt.has_value();})
    ;
