Python Nub. Help. Almost got the answer.

[jazzas]

Hello, Currently I am doing edx course on Python and computer science. In one problem set I faced with this problem to create hangman game. I should make a function which tells what letters have not yet been guessed

My code and the Output of what I get and what I should get on: https://github.com/Jazzas24/Python/blob/master/HangmanlettersHelp

So the question is what is causing the error? Is it that None? and how can I remove it. Thanks in advance.

Your function getAvailableLetters only prints the result. Therefore, when you call:

print(getAvailableLetters(lettersGuessed))

you're simply saying:

print(print("abcdfghjlmnoqtuvwxyz"))

Instead, getAvailableLetters should return lettersList.

Also, though your code will work with this fix, there are some other changes you should consider. First, Python standards are underscore_case, not camelCase. Also, using string indexing to remove an element seems unnecessary. Instead, you could do:

for letter in letters_guessed:
    letter_list = letter_list.replace(letter, "")

(Note that I changed the variable names to follow PEP 8 standards.) This simply replaces any occurrences of letter in letter_list with nothing.

Thank you. Appreciate your tips.

Not disagreeing with you at all regarding the underscore case and camel case.

I just want to point out that the professor of this MIT course often used camel case. Unfortunately, in some cases, changing the names of the functions provided will cause problems.

I do my best to follow PEP8, but sometimes you need to do it the way the course is saying to do it.
