How to import class name python

问题

Here is my python folder structure (it does not have any python package):

 folder/
    script1.py
    script2.py

script1 has:

class myclass(object):
    def __init__():
        print("in init")

    def showReport():
        print("in report only function")

script2 has:

from . import myclass

and when I run python -m folder.script2

I get /usr/bin/python: cannot import name myclass

How can I import this class so that I can call functions from this class on script2?

回答1:

You say you do have a package, but you still have to reference the module script1 that contains your class myclass, so:

from .script1 import myclass

P.S. In Python it's customary to use camel case for class names, so MyClass not myclass

Example

Working example with a package called package and modules module1 and module2, then from outside package, I call python -m package.module2:

➜  ~  tree package

├── __init__.py
├── module1.py
└── module2.py

➜  ~  cat package/module1.py 

class MyClass(object):
    def work(self):
        print 'Working!'

➜  ~  cat package/module2.py 

from .module1 import MyClass

if __name__ == '__main__':
    worker = MyClass()
    worker.work()

➜  ~  python -m package.module2  

Working!

回答2:

Try with from script1 import myclass
