# file one.py
def func():
print("func() in one.py")
print("top-level in one.py")
if __name__ == "__main__":
print("one.py is being run directly")
else:
print("one.py is being imported into another module")
# file two.py
import one
print("top-level in two.py")
one.func()
if __name__ == "__main__":
print("two.py is being run directly")
else:
print("two.py is being imported into another module")
如果你执行one.py文件，
python one.py
会输出：
top-level in one.py
one.py is being run directly
如果你执行two.py文件，
python two.py
会输出：
top-level in one.py
one.py is being imported into another module
top-level in two.py
func() in one.py
two.py is being run directly
Thus, when module one gets loaded, its __name__ equals "one" instead of __main__.
我就不翻译了首先我翻译的很丑其次我觉得英文更好理解。。。
它就是上面这么用的。
然后我觉得它的功能就是，让if __name__ == ‘__main__‘它后面的代码不执行。这样代码运行会更简洁更流畅？？？因为只需要用想用的那部分就行了。。。
