[Project Euler] Fix code style in Problem 41

[jrosellr]

Describe your change:

Addresses #2786

• Improved the problem description with a link
• Added solution function that calls the old function.
• Fixed some doctests, their use was inconsistent with the functions they tested

I have some questions @dhruvmanila :

1. Is it correct to use an assignment inside an f-string? PyCharm is complaining and I can't execute the tests with the current solution call, but I'm leaving it as I found it in the original file.
2. There is one test case (with n = 7) that is cumbersome to put in a doctest, as the call generates a huge list that wraps around many lines, I have left it out and tested directly the solution output, which passes the test case. Should I leave it as it was and undo the changes?

• Add an algorithm?
• Fix a bug or typo in an existing algorithm?

print(f"{max(compute_pandigital_primes(7)) = }")

If you're referring to this then this is not an assignment statement. The = sign in an f-string means that it will produce an output where the expression will be mentioned first then = and then the output of the expression.

Example:

>>> print(f"{1 + 2 = }")
1 + 2 = 3

For 2: leave it as it was

Good increase of pythonicity and code documentation.

[jrosellr]

Alright, I removed the extra function I added and left the old code as it was.

[dhruvmanila]

The answer is actually the maximum value in the list but the function returns a list, we just need the value. Please make the necessary changes as required.
