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()
x that the second function uses have the same value of the global copy of
func_a uses and modifies? When calling the functions after definition, does order matter?
If you want to simply access a global variable you just use its name. However to change its value you need to use the
global someVar someVar = 55
This would change the value of the global variable to 55. Otherwise it would just assign 55 to a local variable.
The order of function definition listings doesn’t matter (assuming they don’t refer to each other in some way), the order they are called does.
