[英]Why dont my functions work?
This is python 3, this code basically checks if a word is the same when read backwards. 这是python 3,此代码基本上检查单词向后读取时是否相同。 When i execute this through Visual Studio, nothing happens, and I get the prompt to press any key to continue...
当我通过Visual Studio执行此操作时,什么也没有发生,并且提示我按任意键继续...
if "__name__" == "__main__":
StartProgram()
def StartProgram():
Input = AskForDataSimple()
print(CheckIfPalindrome(Input))
def AskForDataSimple():
print("Please input the line to test.")
In = input()
return In
def CheckIfPalindrome(x):
if x[::-1] == x:
return True
else:
return False
Please note that this simpler version actually works: 请注意,这个简单的版本实际上可以工作:
x = input()
if x[::-1] == x:
print(True)
else:
print(False)
if "__name__" == "__main__":
Change this to 更改为
if __name__ == "__main__":
__name__
is a variable containing name of this module. __name__
是包含此模块名称的变量。 You need these line so that your main logic would be used only if this file is executed directly, not when imported as a module by another code. 您需要这些行,以便仅在直接执行此文件时才使用您的主要逻辑,而在由另一个代码作为模块导入时则不会使用。
Still it won't work, because you need to define the function you call before these lines: move these lines to the end of the file. 仍然不起作用,因为您需要在这些行之前定义要调用的函数:将这些行移到文件末尾。
Also, this 还有这个
def CheckIfPalindrome(x):
if x[::-1] == x:
return True
else:
return False
can be replaced with 可以替换为
def CheckIfPalindrome(x):
return x[::-1] == x
Move main function to bottom of file and try it 将主要功能移至文件底部并尝试
if __name__ == "__main__":
StartProgram()
