.replace('0', '1') is really a hack. :-) If you want to be clear, if (or filter) would be better. Also, total is a strange name for a product. ;-)

Hi, what kind of name should be appropriate at this kind of case? I used name as "result".

veky on April 12, 2015, 6:37 a.m.
"result" is ok, though a bit "generic" - you don't want to always call your return value the same name, since then you're losing the idea of semantic naming. Appropriate name... how about obvious: "product"?

Thanks veky, I don't pay much attention when I name variables. I will try to stop and think again, before I name my variables.

As they always say, naming variables is like naming your first born child. You have to do it right. :D

Kinda. The only difference is that you have at most one first born child, yet you have about a million variables to name. 😛

In German we have a good name for this <a href="https://de.wikipedia.org/wiki/Querprodukt">Querprodukt</a> which most anybody will recognize as being a close cousin to <a href="https://de.wikipedia.org/wiki/Quersumme">Quersumme</a>. Wikipedia has got it a bit wrong in their "translation"; <a href="https://en.wikipedia.org/wiki/Multiplicative_digital_root">Multiplicative digital root</a> and <a href="https://en.wikipedia.org/wiki/Digital_root">digital root</a> really are the iterative versions of this, the correct translation for Querprodukt is "digital product". The english names aren't quite as descriptive as the german equivalents and don't lend themselves to variable naming as much. Sounds a bit like a song you download off itunes ;-) In short, brush off your German and use querprodukt for the variable name ;-)

clever solution with replace!

Keeping it simple. I like. I wonder if it's faster than list comprehension to "listify" the number and remove the zeroes.

If replace('0','') you have less operation

Generally - .replace() is my favorite. I know, that there are much more efective functions in python, but replace is my first idea everytime :)

the best one! I love it!
