Question

我的代码中存在逻辑错误和错字，已在此处进行编辑和发布

第一个文件：foo.py

import bar
def myname_foo():
    if __name__=='foo':
        print("foo: I have been imported")
    if __name__=='__main__':
        print("foo: I am on my own, i.e., standalone")

if __name__=='__main__':
    myname_foo()
    bar.myname_bar()

第二个文件：bar.py

import foo
def myname_bar():
    if __name__=='bar':
        print('bar: I have been imported')
    if __name__=='__main__':
        print('bar: I am on my own, i.e., standalone')

if __name__=='__main__':
    myname_bar()
    foo.myname_foo()

输出为：

$ python foo.py
foo: I am on my own, i.e., standalone
bar: I have been imported

$ python bar.py
bar: I am on my own, i.e., standalone
foo: I have been imported

Answer 1

您有错字，应使用__main__而不是main。参见main — Top-level script environment作为示例。

Answer 2

您应该更好地检查代码

import foo
def myname_bar():
    if __name__=='foo':
                  ^^^ bar  


if __name__=='__main__':
    myname_bar()
    bar.myname_foo()
    ^^^ foo

之后

$ python  foo.py
foo: I am on my own, i.e., standalone
bar: I have been imported

$ python  bar.py
bar: I am on my own, i.e., standalone
foo: I have been imported

导入和独立功能
