exception handling.
We want to use exception handling if we have any significant recovery

Believe it or not, a change in two characters should make this even faster. :)
Change the line:
file_list = [i[:-1] for i in my_list.readlines()]
to:
file_list = {i[:-1] for i in my_list.readlines()}
The change is to use a "set comprehension" instead of a "list

Files don't rewind automatically, so once a loop goes through the file

One other thing: you might hear another popular approach is to use the

To be specific: your question is on the toplevel round() function.

Hi Daniella,
Your class is using an additional tool called 'pylint' which enforces
certain style conventions.
One of those conventions that Pylint is checking is that variables as
arguments aren't supposed to be all in upper case. Upper case is a
convention for constants, and a variable is not a

OK, so
You should probably look into Biopython:

Your question should involve fairly straightforward use of the Seq methods
of Biopython. You should not try to write your own FASTA parser: Biopython
comes with a good one already.

It's doing a sort, but not in a merging way. Merge sort takes advantage of
a property of the input lists: the input lists are known to be already
sorted.
The general sort routine for lists doesn't take much adv

No; unfortunately Python doesn't make functional approaches as
convenient as I would personally like.
The copy operation on lists itself is expensive to do, so tha
Some code comments: The solution you have depends very much on mutation
and side effects: I recommend you try to stay as functional as you can in
this situation.
By mixing mutation into the solution, there are certain things that the
program is doing that isn't part of the traditional behavior of
