python - A variable in my code won't define properly -
this code maths program making high school. struggling @ moment because can't figure out i've done wrong, says sum1 isn't defined. if please take time go through code , sort out grateful.
my error on line: (line 130)
message_to_screen("what is: " + str(sum1) + " + " + str(sum2), black, -100, "medium")
do let me know if need clarify anything.
thanks!

inside question() function, if value not equal "easy", "medium" or "hard", it'll bump undefined sum1 variable. didn't in line exception raised, best bet.
edit:
ok, reason asked if knew variable scope concepts because see have functions not being called , tries access variables outside scope. suggest further readings variable scoping, immediate answer, following changes in code should work (can't test here):
- in button function
if x + width > cur[0] > x , y + height > cur[1] > y: pygame.draw.rect(gamedisplay, active_color, (x, y, width, height)) if click[0] == 1 , value != none: if value == "easy": easyvalues = list(range(10, 100 + 1)) sum1 = random.choice(easyvalues) sum2 = random.choice(easyvalues) gameloop(sum1, sum2) if value == "medium": mediumvalues = list(range(100, 1000 + 1)) sum1 = random.choice(mediumvalues) sum2 = random.choice(mediumvalues) gameloop(sum1, sum2) if value == "hard": hardvalues = list(range(1000, 10000 + 1)) sum1 = random.choice(hardvalues) sum2 = random.choice(hardvalues) gameloop(sum1, sum2) else: easyvalues = list(range(10, 100 + 1)) sum1 = random.choice(easyvalues) sum2 = random.choice(easyvalues) gameloop(sum1, sum2) - in gameloop function
