Line 6 can be written as number % 3 == number % 5 == 0. More

Using not with 2 branches is usually frowned upon. It's better to reverse branches and eliminate not: if array: return sum ... return 0 Even better is to use try. But you're probably too young for that. :-) More

"if int(digit)" is enough. Or better, to remove duplications of int(...): for digit in map(int, str(number)): if digit: mal *= digit (You can even use filter(None,...) but let's not go there.:) BTW what's "mal" (as a name)? More

First-Gosha

Same as before: if args: return max ... return 0 In new Pythons, you can use default=0 in min and max. More

one-liner-a7295177

Nice "oneliner". :-P But why all those list(...)s? [] are enough. And sum([a,b,a]) is really nicer written as 2*a+b. More

one-liner-a7295177

You can use _and_ for better control flow. ;-) More

Easy-a7295177

What's line 3 for? It was not so hard. :-] More

First-a7295177 1

Why a list?? You never do anything with it except append 1, increment some element (pointless) and return len. More

First-a7295177 1

Aaargh. Don't ever loop over indices when you can loop over values. for char in number: More

Recursion-a7295177 1

You have some really weird ways of thinking. Why outer loop is nice, and inner one is ugly? :-P for i in w: for j in w: More

"a if not b else c" is probably nicer written as "c if b else a". More

About that horrible line 17, I think I have good news for you: tuple comparisons. (a, b) < (c, d) <~~~> a < c or a == c and b < d You can also learn about key argument to min and max. More

First-martin.beseda.3

First, a + a + a is really a*3, even when a is a str. Now you know that, remove the duplication. :-] More

First-martin.beseda.3

You don't need "len(l)". Negative indices are fine. :-) More

"lambda i: abs(i)" has a much nicer name. It has three letters. ;-) Google eta-reduction if you want to know more. ;-) More

Wow, heavy artillery. :-D Even I didn't know about operator.indexOf. Really cool. :-) More

First-martin.beseda.3

This is not C (nor Perl), you don't need parens after while, if, ... base += -c if isfib(c) else 1 "c = 0 # counter" is a really weird comment. If you want to call it counter, do so. You can even have two names: counter = c = 0. :-D Calling "fib" a function that _checks_ whether somethi More

First-martin.beseda.3

Nice homework: now remove _all_ the duplication from that code above. ;-P And don't write empty except. And why float(...), and int(round..., and all. these. parentheses. ?? More

Fourth-martin.beseda.3

Wasn't it easier to just have one "break" instead of lins 10~12? More
