I was attempting a leetcode problem. Here I had to count the number of steps until the variable num is equal to 0. Here is my code:

class Solution:
    def numberOfSteps(self, num: int) -> int:
        step = 0
        while num != 0:
            num //= 2 if not num%2 else num -= 1
            step += 1
        return step

Here is the error from the console output:

  File "/home/syswraith/main.py", line 3
    num //= 2 if not num%2 else num -= 1
                                    ^^
SyntaxError: invalid syntax

Can anyone point out what I am doing wrong? Thanks in advance 🙂
