I was a math teacher in France for two years. I'm currently reconverting to IT, I'm here to improve my Python skills, and practice English.
Coming back to it 19 months later, I still understand it clearly. It makes me happy. ✨
And the only thing I would really change is:
No need of the variable "okay" in the "possible_words" function: the "else" clause would do the job.
changes = []
for rc, letter in z

`items[begin:end]` and `items[end:]` are already sorted, you just need to reverse them so
result += items[begin:end][::-1] # may be possible with one slicing but I'm incomfortable with reversed slices.
result.extend(reversed(items[begin:end]))
a = items[begin:end]; a.reverse(); result

Note that `for each,i in zip(str1, range(len(str1)))` and `for i,each in enumerate(str1)` are equivalent.

You don't need to iterate on the text. You're almost lucky it even works.
def correct_sentence(text: str) -> str:
text = text[0].upper()+text[1:]
if text[-1] != ".":
text += "."
return text

More creative than clear IMO.
No need of parenthesis around `float` or around no rounded result: `round((...), 2)` -> `round(..., 2)`.

I think the "checkio" function should receive only one “step info” each time and process it, instead of giving the entire history, and a coroutine is a good way to do just that. Plus, it's a rare occasion to use `typing.Generator` in a meaningful way.

Use global variables is usually a bad idea, like here. Honestly it should NOT have pass tests. You only pass them because of "check" part work, and little tests did not warn you about it.
assert isometric_strings('add', 'egg') == True
dict == {'a': 'e', 'd': 'g'}
assert isometric_strin

You could use `float('inf')` or `from math import inf` for min_cost.
And global variable are tricky to use. You can define a function into another. Then you won't have to use a global variable.
def cheapest_flights():
min_cost = float('inf')
def cost_calc():
# cost_

I would use "for/else" instead of "flag". What do you think?
for i in range(1, 101):
for j in range(4):
if i % prime[j] != attempts[j + 1][0]:
break
else:
return [2, i]

def cheapest_flight(costs: List, a: str, b: str) -> int:
return min((get_weigth(l, costs) for l in find_all_paths(gen_dict(costs), a, b)),
default = 0)
default value is returned when the iterable is empty.
min([], default=0) == 0
def get_weigth(route, t):

All tests in a quarter of a second on my computer. Fast enough for me.

Great use of numpy and scipy! I like the simplicity that these modules offer to your code, except lines 24-31, I would like a function similar to `pad` to reduce the matrix. :-) Or apply pad function only if it's necessary.

If the iterable is not necessarily a "list of lists of ... of ints/floats", but an "iterable of iterables of ... of not iterables".
def how_deep(iterable) -> int:
try:
return 1 + max(map(how_deep, iterable), default=0)
except TypeError: # not an iterable anymore, re

I really like the fact you use **corners** (so +2). I thought about it too, but my solution worked without this kind of deduction.
Line 54: `for v in range(1, 100):` or `for v in count(1):` itertools count, it's great.
I like to see exceptions raised, but you should create your own exception to be

`num%2==0` is already a boolean True or False, you can return it.
def is_even(num: int) -> bool:
return num%2 == 0

Note that when I published this I could not put it in **creative** category where it clearly belongs.
