list, max and min are builtins. Hint, hint. ;-) More

First-monica

Also could be generator expression (with any), but this is nice too. More

First-monica

OK, but you might want to learn about sets and & (intersection) operator. Faster and cleaner than rolling your own. More

First-monica

That's the way (aha, aha) I like it (aha, aha). :-D More

First-monica

Also obvious. You could check for divisibility by lcm(3,5)=15 in line 12. :-) More

freeman_lex

First-freeman_lex 1

You could have cached that range(len(D)). And "if 0 in bla" is here "if not all(bla)". ;-) More

First-rbrian 1

You can initialize all (l13~15) at once: lower = upper = digit = 0 You can ask ints for truth directly: return len(data) >= 10 and digit and upper and lower More

First-rbrian

Too many cases. ;-P Also, writing '00' instead of '100' is deeply confusing. :-P More

First-rbrian 1

It's "length". Not that it matters much. :-) More

sorted frequency dictionary-rbrian 1

1. You don't need to sort and extract just to find maximum. See max with key argument. 2. Lines 4~6 can just be "for letter in text.lower():". This is not C, text will be lowered only once in any case. 3. Line 8 is pretty ugly. You can use defaultdict(int), but even better, the name of a varia More

create possibilities list-rbrian 1

You don't need copying in line 9. Unpacking is much better when you use it consistently with your structure: line 6 is row_zero, row_one, row_two = game_result range(0,3) is range(3). Or even better, use zip(row_zero, row_one, row_two). That "str"s everywhere are probably worse than More

First-rbrian 1

Whenever you import copy, a python dies somewhere. ;-P More

bunnychai

OilPie-bunnychai

"size+g" is not really clear. But neither is input format, so... :-) More

smilicic

First-smilicic

Hm, this gives me some [idea](http://www.checkio.org/mission/digit-stack/publications/veky/python-3/pointless/)s... :-] More

Second-martin.beseda.3

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

First-martin.beseda.3

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

gyahun_dash

itertools-gyahun_dash 1

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