change value in functions(from out of function)-CodePudding

i need to change CHECKER value to 1 but i cant.

NUM0 = 0
CHECKER = 0
def ITEM():
     if CHECKER == 0 :
           NUM1 = NUM0
           CHECKER = 1

CodePudding user response：

If I understood you correctly, just change the last line to this:

CHECKER  = 1

CodePudding user response：

Take CHECKER as a global variable inside function

NUM0 = 0
CHECKER = 0
def ITEM():
    global CHECKER #this will solve your problem  
    if CHECKER == 0 :
        NUM1 = NUM0
        CHECKER = 1

CodePudding user response：

Declare your variable global to modify it:

NUM0 = 0
CHECKER = 0
def ITEM():
     global CHECKER  # <- HERE
     if CHECKER == 0 :
           NUM1 = NUM0
           CHECKER = 1

CodePudding user response：

You don't call your function. This will work for you:

NUM0 = 0
CHECKER = 0
def ITEM():
     if CHECKER == 0 :
           NUM1 = NUM0
           CHECKER = 1
ITEM()
