This article describes the scope of the Python variable. Share it with you for your reference. The details are as follows:

# Coding = UTF-8 # variable scope: global z # use the global variable z = 1 # assign a value to the global variable x = 99 # x when declaring the global variable def foo (y ): # y and z are assigned values in the function: Partial # Partial Region z = x + y # x is not assigned values, so it is the global return zdef bar (y ): global z = x + y return zprint foo (1) # result = 100 print z # result = 1 print bar (1) # result = 100 print z # result = 100

I hope this article will help you with Python programming.
