Printing the numbers from 1 to 100 and skipping the numbers divisible by 3 or 5. An indentation mistake returning two values

I want to print the numbers from 1 to 100 and skip the numbers divisible by 3 or 5. I made an indentation mistake I got two values. What is the logic?

Here is the code:

i = 1
while i<=100:
    if not(i%3==0 or i%5==0):
        print(i,end="   ")
        i=i+1  ***indentation mistake***

@Thymen Already explained it very well in the comments, but basically if not (i%3==0 or i%5==0): will mean that if the number is divisible by either 3 or 5 then of course the code inside the if block will not be executed. This means that as soon as i=3, the if block will be skipped and the while loop will continue, without having incremented i, which leads to an infinite loop.

As a side note I would write this with a continue statement so it's clear what you're doing:

i = 0
while i < 100:
    i += 1
    if not i % 3 or not i % 5:
        continue
    print(i, end="   ")
