Find negative Numbers in list and change | Python

Question

I want to sort out all Numbers under 0 in a List and add to the numbers under 0 + 500.

import random
from turtle import st

startFrame = random.randint(0, 200)

print(startFrame)

start = []

for i in range(startFrame -125, startFrame):
    
    start.append(i)

print(start)

for Frame in start:
    
    if Frame > 0:
        
        Frame + 500
        
print(start)

Did anyone can find out why its not working?

Answer 1

Just do the following:

for i in range(len(start)):
    if start[i] < 0:
        start[i] += 500
print(start)
