define a global variable 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
