how to use global in python code example

Example 1: python access global variable

globvar = 0

def set_globvar_to_one():
    global globvar    # Needed to modify global copy of globvar
    globvar = 1

def print_globvar():
    print(globvar)     # No need for global declaration to read value of globvar

set_globvar_to_one()
print_globvar()       # Prints 1

Example 2: python global variables

global var1
var1 = 'whatever'

Example 3: global in python

a = 'this is a global variable'
def yourFunction(arg):
    #you need to declare a global variable, otherwise an error
    global a
    return a.split(' ')

Example 4: how to make variable global in python

global variable
variable = 'whatever'

Example 5: how to make a variable global in python

x = 5 #Any variable outside a function is a global variable

def GLOBAL():
	global y #if a variable is inside a function, use the 'global' keyword
    y = 10 # now this variable (y) is global

Example 6: global python

"""
USING GLOBALS ARE A BAD IDEA, THE BEST WAY TO PERFORM AN ACTION WHICH NEEDS GLOBALS WOULD 
BE TO USE RETURN STATEMENTS. GLOBALS SHOULD ONLY EVER BE USED IN RARE OCCASIONS WHEN YOU
NEED THEM
"""

# allows you to modify a variable outside its class or function

EXAMPLE:
  
def test_function():
  global x
  x = 10

test_function()
print(f"x is equal to {x}") # returns x is equal to 10
