how to make a variable global in python

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

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

global variable python

# Python global variable
# Probably should not use this, just pass in arguments

x = 0 # variable is in outer scope
print(x) # prints x (0)

def use_global_variables():
  # if using a global variable, the variable will not need to be mention while calling the function
  global x # calling the x variable from a function
  x += 1
  print(x) # prints x after adding one in the function (1)

globals() method python

"""
Through the globals() function, one can bind a variable to a set 
as illustrated below. name str variable was both bound to different
sets and used to modify these sets. 
"""

set2 = set()
set3 = set()

for i in range(1, 4): 
	globals()[name + str(i)].add(i)  # access ith set and add value of i to it
