大家好，又见面了，我是你们的朋友全栈君。
执行当前文件中： __name__ == ‘__main__’ 是返回true，引用模块中的则返回false
如：现在有两python文件，one.py 和 two.py
# 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")发布者：全栈程序员栈长，转载请注明出处：https://javaforall.cn/156109.html原文链接：https://javaforall.cn
