Python function global variables?

Question

I know I should avoid using global variables in the first place due to confusion like this, but if I were to use them, is the following a valid way to go about using them? (I am trying to call the global copy of a variable created in a separate function.)

x = "somevalue"

def func_A ():

global x

# Do things to x

return x

def func_B():

x=func_A()

# Do things

return x

func_A()

func_B()

Does the 'x' that the second function uses have the same value of the global copy of 'x' that 'func_a' uses and modifies? When calling the functions after definition, does order matter?

Answer 1

The global variables can be accessed by its name only. But to change its value you need to use the global keyword.

Example:-

global abc

abc = 55

The above code will change the value of the global variable to 55. Otherwise, it would just assign 55 to a local variable.
