How to solve the problem of a None when executing the Python code?

This article mainly introduces "how to solve a None in the result of executing Python code". In daily operation, I believe that many people have doubts about how to solve a problem in the result of executing Python code. Xiaobian consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the doubt that "there is a None solution to the result of executing Python code." Next, please follow the editor to study!

Example of the exercise:

#! usrbinpython

# Filename wqmodule.py

Def avg (a meme baud 1 dint 2):

Print (a+b+c) / 3

#! / usr/bin/python

# Filename: wqmodule_demo.py

Import wqmodule

Print 'demo-avg is', wqmodule.avg (10)

Executing python wqmodule_demo.py returns:

Demo-avg is 4

None

There is a None at the end of execution because the python function returns a value using return, if not

Return, and use print to output the value, this function also has a default return value of None.

We can change the print in wqmodule.py to return, and that's fine.

At this point, the study of "how to solve the result of executing Python code with a None" is over. I hope to be able to solve everyone's doubts. The collocation of theory and practice can better help you learn, go and try it!
