It's starting to get very cold (at least on the Northern hemisphere) so we
have been carefully packaging a total of three new Python releases to keep
you warm these days!
Python 3.9.1 is the first maintenance release of Python 3.9, and also the
first version of Python to support macOS 11 Big Sur n

Beware though that either of these will be slow if your list of dicts is large.

But what is passed in kwargs will not necessarily have values for all
of the keys and I only want to check f
You can return dictionaries that returns True if
(a.items() & kwargs.items()) == kwargs.items()
when `a` is one of your dicts.

Not sure why you want to do this (it's schoolwork)? Anyway, this is my version:
word = input('input word you want to change letters in: ')
chars = tuple(word)
change_this = input('Enter the letters you want to change: ')
replace_with = input('Enter the letters to replace with: ')
if len(change_t

Besides what others have said (especially re using a dict instead), I think
it's unpythonic/can result in unexpected behavior to change a list as it's
being iterated over. Your modified word_list should be a separate list, I
think.
Also, if you use enumerate(), you won't have to use .index and it w

The only comment I have is that you didn't check the inputs at all. Suppose
the word I type in is "1234". 1234 will turn into an int, not a string.
You can't index through an int, it's one thing. So the program will probably
throw an error.
If the word at least starts with a letter, then it

And sometimes "handling" is just printing some extra stuff and then

Regarding the solution of linear algebraic equations I noticed a big
difference in the computation
time in Python compared to the old fortran language.
I have compared both the linelg and lapack.dgesv-lapack.zgesv modules with

The difference in computation time is
