We shall not cease from exploration, and the end of all our exploring will be to arrive where we started and know the place for the first time.
First, a defaultdict would _really_ help here. :-)
Second, you don't need () inside [] indexing. Just d[i, j].
Third, end of line 11 can be just `... else max((n1, s1), (n2, s2))`. Tuples compare sensibly. :-)
And fourth, you can get by without tracking lengths all the time, just calculate when n

Yes, this is much nicer.
That ugly last line indexing, it could have been just d[max(d)], right? :-)

Not boring at all. That [Chekhov's product](https://en.wikipedia.org/wiki/Chekhov's_gun) in first line is very interesting. I deeply wonder what was its intended purpose in the never-revealed third line. :-DD

... if array ... is much better than ... if len(array). If you really want to use len(array), you can use and. :-)
len(array) and sum(...)*...

... except if array is empty, then it cannot. ;-D

Please don't use find if you just want to see whether something is _in_ something else.
if a.find(b) >= 0: ~~~~> if b in a:
Also, sum is a builtin. You can use it directly instead of rewriting it. ;-)
return sum(word in text for word in words)

Too many "list"s (in cols).
You don't need () around '\_\_\_' in lines.
You don't need 0 and 9 (len) in slices: inline[::4].
If you're really obsessed with speed, try inlining diags and cols. Also try extending rows directly instead of copying.

Nice. Could be a bit simpler if you pulled int conversion into iteration itself:
for digit in map(int, str(number)):
if digit:
result *= digit
And use *= and similar assignments... they do make code easier to read.

A minor philosophical point: "result" would probably

Line 4 is a perfect example of what horribilities people go through, just to avoid writing another newline. It's not worth it. :-P
digit = int(i)
if digit:
s *= digit

Line 1 is unnecessary in principle, but even if this were Python2, it would still be unnecessary, since it specifies the coding of _source text_, and there you don't have any funny characters. :-)
BTW that three-char indent really stabs the eye. ;-P

Use // for int division, much more readable than int(/). You can also use divmod since you need both size % 2 and size // 2. And eliminate duplication, there's no need to write med calculation twice.
You can also use if...else expression, but it's not necessary. And a wizard would use `data[med] +

First, read about `collections.Counter`. It will make your life a lot easier.
Second, `dict()` is `{}`. But you probably knew that. :-)
Third, drop [] inside (). They are just slowing you and Python down. `sorted(k for ...)`.
And fourth, `sorted(blah)[0]` is really more readable and more efficien

count\_diff is very nonclear IMO. :-P Much simpler would be to do what the name says, instead of complement\_of\_count\_eq :-P
sum(f != s for f, s in ...)
\+ what nickie said. Python list is really an array, but that precisely means that pop(0) is O(n). deque is what you need (or better a

Nice contortions you're going through just to get it all in one line. I even learned something (locals can't be changed live, but function dicts are fair game:). It can be made much shorter if you want, though. For example, e[0] if e[1]==k else e[1] can be written as e[e[0]==k]. Also, {e for e in E

* About that htoi function: int accepts second argument as base. htoi(a) is in fact int(a,16). revsum can also be written using it, you just have to reverse the string: int(a[1::-1],16) Line 44 could also use revsum, right?
* That while loop instead of for is really jarring. And its body could mu

Meh... I expected more of you (for example, calculating probability distributions, and guessing most probable things:).
BTW, it's surprising you don't use chaining:
0 <= i < N
it really is more readable (at least Guido thinks so:).
Nice check if field is empty. :-)
If neighbors we

LOL, this is actually an interesting one. I'd even give it a few thumbs if you change the category. :-P
