Change variable from another scope without using global?

I am new to Python.

How can I accomplish something like this:

def gameon():
  currentNum = 0
  for x in range(100):
    currentNum+=1
    otherfunc()

def otherfunc(maybe a possible parameter...):
  for y in range(500):
    #check for some condition is true and if it is... 
    #currentNumFROMgameon+=1

My actual code that used global variables:

def gameon():
  global currentNum
  currentNum = 0
  for x in range(100):
    currentNum+=1
    otherfunc()

def otherfunc():
  global currentNum
  for y in range(500):
    if(...):
      currentNum+=1
global currentNum

How can I accomplish this(accessing and changing currentNum from otherfunc) without making currentNum global?

If you want to have access to currentNum in otherfunc you should pass it to that function. If you want otherfunc to change it, simply have it return an updated version. Try this code:

def gameon():
  currentNum = 0
  for x in range(100):
    currentNum+=1
    currentNum = otherfunc(currentNum)

def otherfunc(currentNumFROMgameon):
  for y in range(500):
    if True: # check your condition here, right now it's always true
      currentNumFROMgameon+=1
  return currentNumFROMgameon
