Cave of Python

It’s easy to import only parts of a package in Python. You can import a particular module (file) from a package, or particular classes, functions or constants (variables) from a module.

The syntax looks the same or similar in all of these cases.

Consider this module:

mystuff/mymodule.py

def greet():
    print("Hello")

def another_function():
    print("Zzzzzzz")

def main():
    greet()

if __name__ == "__main__":
    main()

If we want to import only the greet function, we can do this:

from mystuff.mymodule import greet

greet()

output:

Hello

Import Examples

The following are all valid import statements, given the above code.

from mystuff.mymodule import greet as g
from mystuff import mymodule as mm
from mystuff.mymodule import greet as g, another_function as func

g()

mm.greet()

func()

output:

Hello
Hello
Zzzzzzz
