+2 for `:=`

is that a new update of Python?

：= only use in py3.8 before v3.8: len(str(num)) - len(str(num).rstrip('0'))

`:=` , not `: =`

smart yet simple. Learnt from this. how does one familiarize with such unusual syntaxes?

Gerstox on May 14, 2020, 6:52 p.m.
I seem very good your solution, and i've learn the rstrip() function! awesome!

Wow! I need some Python syntax update on this. :)

Looks nice

Nice use of the new "walrus operator" there! Loved this solution purely on that basis alone!

nice

A smart, beautiful, and concise Pythonic way

Why rstrip() and not just strip()? An integer (beside zero itself) never starts with a 0 ;)

tom-tom on Aug. 25, 2020, 8:23 a.m.
strip has less letters in its name, but rstrip does less work (I suppose).

tom-tom on Aug. 25, 2020, 9:52 a.m.
And, even more important, rstrip describes intention better.

moosetraveller on Aug. 25, 2020, 2:08 p.m.
That's a solid argument.

It Was Awesome!

3 text operations, one conversion - your CPU would start throttling if you continue this way. I guess division is much faster.

Make your solution, do a performance comparison, and put it in the Speedy category (or not).

good job

I would rather have it two lines for clarity, readability, as well most of us do not have python 3.8 yet ```python def end_zeros(num: int) -> int: s = str(num) return len(s) - len(s.rstrip('0')) ```
