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

how to acess global variables within function python

#A global variable can be accessed from any function or method.
#However, we must declare that we are using the global version and not the local one.
#To do this, at the start of your function/method write "global" and then the name of the variable.
#Example:
myVariable = 1

def myFunction():
  global myVariable
  print(myVariable)

myFunction()

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)
