python create global variable in function 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: global variable python

#it is best not to use global variables in a function
#(pass it as an argument)
a = 'This is global a'
def yourFunction():
    global a
    return a[0:2]

Example 6: 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
