while 函数 python
你好,使用 eclipse 和 pydev,我想知道为什么我的示例代码无法尝试使用 while 函数。
print("Welcome to the annoying program")
response = ""
while response != "Because.":
response = input("why\n")
print("Oh,ok")
输出如下:
Welcome to the annoying program
why
Because.
Traceback (most recent call last):
File "/Users/calebmatthias/Document/workspace/de.vogella.python.first/simpprogram.py", l ine 9, in <module>
response = input("why\n")
File "/Users/calebmatthias/Desktop/eclipse 2/plugins/org.python.pydev_2.2.3.2011100616/PySrc/pydev_sitecustomize/sitecustomize.py", line 210, in input
return eval(raw_input(prompt))
File "<string>", line 1
Because.

Hello is use eclipse and pydev, I was wondering why my sample code won't work trying to use the while function.
print("Welcome to the annoying program")
response = ""
while response != "Because.":
response = input("why\n")
print("Oh,ok")
the output is the following:
Welcome to the annoying program
why
Because.

2.x 中的
input
函数将输入计算为 Python 代码!请改用raw_input
函数。使用
输入
,输入“因为”文本。正在计算,这是一个语法错误,因为点后面没有跟任何东西。The
input
function in 2.x evaluates the input as Python code! Use theraw_input
function instead.With
input
, your text "Because." is being evaluated, and it's a syntax error because the dot isn't followed by anything.
