python 模块的__name__ __main__
每个模块都有一个名称,在模块中可以通过语句来找出模块的名称。这在一个场合特别有用
——就如前面所提到的,当一个模块被第一次输入的时候,这个模块的主块将被运行。
每个Python模块都有它的__name__,如果它是'__main__',这说明这个模块被用户单独运行,
我们可以进行相应的恰当操作。
#!/usr/bin/python
# Filename: using_name.py
if __name__ == '__main__':
print 'This program is being run by itself'
else:
print 'I am being imported from another module'
输出
$ python using_name.py
This program is being run by itself
$ python
>>> import using_name
I am being imported from another module
