__file__:获取到当前的文件路径 为了加深理解,下面以hello.py脚本为例加以说明。首先在桌面创建hello.py,内容如下: # -*- encoding=utf-8 -*- ''' this is a hello script.''' def function1(): '''this is function1 usage''' print("this is function1") if __name__ == '__main__': ...
if __name__=='__main__'说白了就是判断__name__变量是不是等于__main__,当执行文件本身时候__name__变量等于main,此时判断成立并执行判断语句中的代码,当调用该模块的时候__name__并不等于__main__条件不成立,不执行判断下面的语句,可以认为为了调试模块,因为在模块导入的时候并不执行if下面的语句。
