All functions in the subprocess module are convenience wrappers around the Popen() constructor and its instance methods. Near the end of this tutorial, you’ll dive into the Popen class. Note: If you’re trying to decide whether you need subprocess or not, check out the section on deciding...

在前面的学习过程中也用到了一些函数,如果len()、min()和max(),这些函数都由Python官方提供的,称为内置函数(Built-in Functions, 缩写BIF)。 注意 Python作为解释性语言函数必须先定义后调用,也就是定义函数必须在调用函数之前,否则会有错误发生。 本节介绍自定义函数,自定义函数的语法格式如下: ...
Note: When the debugger performs a reload, code that runs on import might be executed again. To avoid this situation, try to only use imports, constants, and definitions in your module, placing all code into functions. Alternatively, you can also useif __name__=="__main__"checks. ...
