global variable python

Comment

# 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)
  
use_global_variables

=============================================
# Output:
0
