TypeError with 'module' object is not callable

Question

I have a test folder the structure within the folder

__init.py__
aa.py
test.py

for aa.py

class aa:
    def __init__(self,max):
        self.max=max
        print max+1

    def hello(self):
        print(max)

for test.py

import aa
abc = aa(100)
abc.hello()

when run test.py , I have an error

    abc = aa(100)
TypeError: 'module' object is not callable

What is the problem?

Answer 1

You have a module aa , and in that module you have a class aa . You only import the module.

Either do:

import aa
abc = aa.aa(100)

or:

from aa import aa
abc = aa(100)

or, even better, use separate names for module and class.

Answer 2

you need to do like this.

from aa import aa
abc = aa(100)
abc.hello()

Answer 3

使用from aa import *代替test.py脚本中的import aa 。
