我将为Route组件提供一个React键。 country状态将是一个很好的候选人,因为当语言更改时,密钥将在更改。当密钥更新路由组件将重新启动。

例子:

<Route key={this.state.Country} exact path="/">
  <News
    key="general"
    pageSize={this.props.pageSize}
    country={this.state.Country}
    category={"general"}
  />
</Route>

I would provide a React key to the Route component. The Country state would be a good candidate since the key would be changing when the language changes. When the key updates the Route component will remount.

Example:

<Route key={this.state.Country} exact path="/">
  <News
    key="general"
    pageSize={this.props.pageSize}
    country={this.state.Country}
    category={"general"}
  />
</Route>

您可以使用xamarin.forms.combobox。从管理Nuget软件包安装它。

XAML:

  <combobox:ComboBox x:Name="comboBox" 
                           ItemsSource="{Binding ItemsSource}"                                   
                           SelectedItemChanged="ComboBox_SelectedItemChanged"                                
                           Visual="Material">
            <combobox:ComboBox.ItemTemplate>
                <DataTemplate>
                    <ViewCell>
                        <Label Text="{Binding .}" Padding="5,5,0,0"/>
                    </ViewCell>
                </DataTemplate>
            </combobox:ComboBox.ItemTemplate>
        </combobox:ComboBox>

代码:

public partial class Page3 : ContentPage
{
    public Page3()
    {
        InitializeComponent();
        this.BindingContext=new Page3ViewModel();
    }

    private void ComboBox_SelectedItemChanged(object sender, SelectedItemChangedEventArgs e)
    {
        comboBox.Text = comboBox.SelectedItem.ToString();
    }       
}

public class Page3ViewModel
{
    public List<string> ItemsSource { get; set; }   
    public Page3ViewModel()
    {
        ItemsSource = new List<string>()
        {
            "Item1",
            "Item2",
            "Item3",
            "Item4"
        };

    }
  }
  }

You could use Xamarin.Forms.ComboBox. Install it from Manage NuGet Packages.

Xaml:

  <combobox:ComboBox x:Name="comboBox" 
                           ItemsSource="{Binding ItemsSource}"                                   
                           SelectedItemChanged="ComboBox_SelectedItemChanged"                                
                           Visual="Material">
            <combobox:ComboBox.ItemTemplate>
                <DataTemplate>
                    <ViewCell>
                        <Label Text="{Binding .}" Padding="5,5,0,0"/>
                    </ViewCell>
                </DataTemplate>
            </combobox:ComboBox.ItemTemplate>
        </combobox:ComboBox>

Code:

public partial class Page3 : ContentPage
{
    public Page3()
    {
        InitializeComponent();
        this.BindingContext=new Page3ViewModel();
    }

    private void ComboBox_SelectedItemChanged(object sender, SelectedItemChangedEventArgs e)
    {
        comboBox.Text = comboBox.SelectedItem.ToString();
    }       
}

public class Page3ViewModel
{
    public List<string> ItemsSource { get; set; }   
    public Page3ViewModel()
    {
        ItemsSource = new List<string>()
        {
            "Item1",
            "Item2",
            "Item3",
            "Item4"
        };

    }
  }
  }

最后{}应该像这样:

}else{
      var currScale = 0.8;
      matrix = Matrix4.diagonal3Values(1, currScale, 1)..setTranslationRaw(0, _height*(1-_scaleFactor)/2, 1);
    }

Last else{} should look like this:

}else{
      var currScale = 0.8;
      matrix = Matrix4.diagonal3Values(1, currScale, 1)..setTranslationRaw(0, _height*(1-_scaleFactor)/2, 1);
    }

Matrix4在颤音中过渡

您可以使用 groupby.agg 在由连续值形成的组上,然后获取第一个减去最后值(有关变体,请参见下文):

out = (df.groupby(df['Status'].ne(df['Status'].shift()).cumsum())
         ['Count'].agg(lambda x: x.iloc[-1]-x.iloc[0])
       )

输出:

Status
1    3
2   -6
3    2
4    0
Name: Count, dtype: int64

如果您只想对一个以上元素组的组进行此操作:

out = (df.groupby(df['Status'].ne(df['Status'].shift()).cumsum())
         ['Count'].agg(lambda x: x.iloc[-1]-x.iloc[0] if len(x)>1 else pd.NA)
         .dropna()
       )

输出:

Status
1     3
2    -6
3     2
Name: Count, dtype: object

输出为dataframe:

add .rename_axis('cycle')。reset_index(name ='nounding')

out = (df.groupby(df['Status'].ne(df['Status'].shift()).cumsum())
         ['Count'].agg(lambda x: x.iloc[-1]-x.iloc[0] if len(x)>1 else pd.NA)
         .dropna()
         .rename_axis('Cycle').reset_index(name='Difference')
       )

输出:

   Cycle Difference
0      1          3
1      2         -6
2      3          2

You can use a GroupBy.agg on the groups formed of the consecutive values, then get the first minus last value (see below for variants):

out = (df.groupby(df['Status'].ne(df['Status'].shift()).cumsum())
         ['Count'].agg(lambda x: x.iloc[-1]-x.iloc[0])
       )

output:

Status
1    3
2   -6
3    2
4    0
Name: Count, dtype: int64

If you only want to do this for groups of more than one element:

out = (df.groupby(df['Status'].ne(df['Status'].shift()).cumsum())
         ['Count'].agg(lambda x: x.iloc[-1]-x.iloc[0] if len(x)>1 else pd.NA)
         .dropna()
       )

output:

Status
1     3
2    -6
3     2
Name: Count, dtype: object

output as DataFrame:

add .rename_axis('Cycle').reset_index(name='Difference'):

out = (df.groupby(df['Status'].ne(df['Status'].shift()).cumsum())
         ['Count'].agg(lambda x: x.iloc[-1]-x.iloc[0] if len(x)>1 else pd.NA)
         .dropna()
         .rename_axis('Cycle').reset_index(name='Difference')
       )

output:

   Cycle Difference
0      1          3
1      2         -6
2      3          2

当创建test-device-auth-auth-private.pem时,它不是作为加密的键Blob创建的,因此不需要密码。您可以通过openssl pkcs8-in test-device-auth-private.pem -out test-test-device-auth-private-enc.pem -topk8进行加密加密。

When test-device-auth-private.pem was created it wasn't created as an encrypted key blob, so no passphrase is needed. You can encrypt it via something like openssl pkcs8 -in test-device-auth-private.pem -out test-device-auth-private-enc.pem -topk8 and give a password at the prompt.

从技术上讲,它们并不相同,尽管它们似乎有时可能具有相同的行为,但它们被用来代表对象的特定生命周期阶段。

瞬态在使用关键字new创建对象的初始状态期间应考虑对象的初始状态,然后仅将这些对象视为存储器中存在,并且将是垃圾一旦所有参考都消失了,就会收集。但是,由于瞬态状态是对象生命周期的开始,因此可以稍后将其提交到托管状态,并最终永久存储在数据库中。

删除状态是对象通常在提交过程中从基础数据库手动删除物理删除的对象的最后一个可能的状态,即对于已经存储在该状态DB,但不再需要。

是的IE 瞬态状态的末端,该状态在删除最后一个参考后可能未移至托管状态,而没有剩下任何记录。
删除的状态的末端已从其存在的数据库中物理删除,该对象曾经存在,没有剩下的,因此没有记录。

Technically they are not the same, although that they may appear to be seen as to have the same behaviour at times, but they are used to represent specific life cycle stage for an object.

Transient should be considered during the initial state for an object when the object is created using the keywords new, these objects are then only considered to be existing in memory and will be garbage collected as soon as all references of them is gone. But since the Transient state is the start of an object's lifecycyle, it may later be put forward into a managed state and eventually be permanently stored in the database.

Removed state is the last possible state for an object usually when it has been manually staged for physical deletion from the underlying database during commit, i.e. the this state is usually reachable for an object that is already stored in the db, but is no longer needed.

So yes, when you look at them in isolation, close to the end of each of these two life cycle events once their effect takes in place, they may look the same, i.e. end of a transient state of which the object may not have been moved into an managed state after the last reference is removed, nothing is left, hence no records.
The end of removed state of which an object has been physically deleted from the database where it once exists, nothing left, hence no record again.

JPA中的瞬态状态和删除状态有什么区别?

一点点JavaScript可以帮助您。通过获得最大高度,您可以将其定义为所有类

function textHeight() {
  var reed = document.getElementsByClassName("titles")

  let lengths = Array.from(reed).map(e => e.offsetHeight);
  let max = Math.max(...lengths);

  for (let i = 0; i < reed.length; i++) {
    reed[i].style.minHeight = max + "px"

A little bit of JavaScript can help out . By getting the maximum height , you can define that to all classes

function textHeight() {
  var reed = document.getElementsByClassName("titles")

  let lengths = Array.from(reed).map(e => e.offsetHeight);
  let max = Math.max(...lengths);

  for (let i = 0; i < reed.length; i++) {
    reed[i].style.minHeight = max + "px"
  }
}
textHeight();

对齐不同块的子元素

深白境迁sunset 2025-02-18 05:58:40

假设l您的输入列表,您可以使用列表/字典理解:

df = pd.DataFrame([{k:v for d in l for d in l for k,v in d.items()} for l in L])

nb。请注意,您的字典中有重复的键, last 一个优先级

输出:

  aaa bbb ccc ddd eee
0  42  60  25  14  84
1   4   0  25   1   8

输入:

L = [[{'aaa': '42'}, {'bbb': '60'}, {'ccc': '25'}, {'ddd': '14'}, {'eee': '15'}, {'eee': '84'}],
     [{'aaa': '4'}, {'bbb': '0'}, {'ccc': '25'}, {'ddd': '1'}, {'eee': '1'}, {'eee': '8'}]]

Assuming L your input list, you can use a list/dictionary comprehension:

df = pd.DataFrame([{k:v for d in l for d in l for k,v in d.items()} for l in L])

NB. note that you have duplicated keys in your dictionaries, the last ones take precedence

output:

  aaa bbb ccc ddd eee
0  42  60  25  14  84
1   4   0  25   1   8

input:

L = [[{'aaa': '42'}, {'bbb': '60'}, {'ccc': '25'}, {'ddd': '14'}, {'eee': '15'}, {'eee': '84'}],
     [{'aaa': '4'}, {'bbb': '0'}, {'ccc': '25'}, {'ddd': '1'}, {'eee': '1'}, {'eee': '8'}]]

如何将嵌套列表转换为数据框

在代码的最后一个循环中:

for date in monthDatesList:
    print(date)

您正在重新分配dateTime模块的日期函数函数montrydateslist中的元素。我将其重命名为monthdate之类的东西,以确保您不会覆盖date函数。命名变量不覆盖您要导入的任何内容时,请始终小心

In the last for loop of your code:

for date in monthDatesList:
    print(date)

you are reassigning the datetime module's date function to an element in monthDatesList. I would rename it to something like monthDate to make sure you're not overwriting the date function. Always be careful when naming variables to not overwrite anything you're importing

dateTime.date对象不可呼应

如果有任何警告/错误/等,则汇编将失败。被编译器抓住。

I would suggest that you choose from Visual Studio Code the option Terminal > New Terminal and manually compile your source file with something similar to the following:

您的代码有许多问题,这些问题阻止它按照您的期望工作:

  • 您没有正确声明构造函数。当您执行员工('abs',200)时,Python在类对象上寻找一个称为__ INT __ INT __ INT __的函数。您将构造函数声明为员工,与您在基于C的语言中的方式相似。这行不通。
  • 您将员工数量存储为范围范围对象对象的变量。您可以做到这一点,但我不会,因为这是对这种能力的滥用。相反,您应该创建一个员工列表并获取列表的长度。
  • 您应该超载__ str __函数,而不是声明display函数,该功能返回代表对象的字符串。
  • 班级名称应该是pascalcase(这不能防止您的代码工作,但您绝对应该解决它)。
class Employee:

    def __init__(self, name, salary):
        self.name = name
        self.salary = salary

    def __str__(self):
        return f"Name: {self.name}, Salary: {self.salary}"

employees = []
employees.append(Employee('ABS', 200))
len(employees) # 1

Your code has a number of problems that are preventing it from working as you expect:

  • You did not declare your constructor properly. When you do employee('ABS', 200), Python looks for a function called __init__ on the class object. You declared your constructor as employee, similarly to how you would do so in C-based languages. This won't work.
  • You store the employee count as a variable scoped to the class object. You can do this but I wouldn't because it's a misuse of that capability. Instead, you should create a list of employees and get the length of the list.
  • Instead of declaring display functions, you should overload the __str__ function, which returns a string representing the object.
  • Class names should be PascalCase (this doesn't keep your code from working but you should definitely address it).
class Employee:

    def __init__(self, name, salary):
        self.name = name
        self.salary = salary

    def __str__(self):
        return f"Name: {self.name}, Salary: {self.salary}"

employees = []
employees.append(Employee('ABS', 200))
len(employees) # 1

缺少1个必需的位置参数(EMP1)
