    Converting a string containing Uppercase/Lowercase/whitespace/characters to lowercase

    Hello, I have been looking around to find help on how to convert a string containing Uppercase/Lowercase/Whitespace/Special Characters to only Lowercase and removing the whitespace and characters.

    For example, a message like:

    "The: sky is (blue), the wAter is also blue'."

    Change that message to:

    "theskyisbluethewaterisalsoblue"

    Thanks in advance for the help!

    That is, reasonably obviously, a homework exercise - and this site has a homework policy here. You need to demonstrate a genuine attempt before expecting help. As yet, you have demonstrated no such attempt.
    Right 98% of the time, and don't care about the other 3%.

    If I seem grumpy or unhelpful in reply to you, or tell you you need to demonstrate more effort before you can expect help, it is likely you deserve it. Suck it up, Buttercup, and read this, this, and this before posting again.

    Yes, it is part of a project that I would love to get help on, but this is only a small part of it. The entire homework assignment involves using the Hill Cipher to encrypt a message. The message I need to encrypt is very large and has a lot of different characters in it as well as uppercase letters. In order for me to encrypt my message I need to change the entire message to lowercase with no whitespace and I was just looking for help on how to do that. I have researched about how to do so on the internet but I can only find ways to do one or the other and not both together so I was hoping someone here would know how to do them all together.

    So, you need to learn to program instead of copy and paste the work of others.

    If you know how to do both separately, couldn't you use the solutions you've found one after the other? If you want the board to help you further, try your best attempt with what you know, show the code you've tried here and then ask for specific help on getting it to work. That way you'll learn more and the people here will probably be more motivated to help.

    It can help to break procedures into multiple simpler ones. Consider the following break-down.

    * Translate upper-case to lower-case characters in a string.
    * Remove characters, in a string, that are not lower-case.

    See whether you can write two functions that do these things, then combine them.
