convert string to list

hi cxr,

I am actually just trying to learn Python, so I was trying many things,

I will verify the code that you sent me, at the same time, I can give you 50 points for each question that I have,

1) I still need to know how to reverse a list,

2) and for example, if I have a string that has letters and digits, how Do I just get the sum of the digits

3) If I have values with strings and digits, I want to pass the string and get the digits assoicated to it

4) If I have a list of strings, how do I make the first letter capital in all of them, and rest all lower case, for example `pyThon`` to ``Python``

Thanks for your help CXR

also, can you provide any link that provides beginners some guidance to Python.

This question is worth 500 points now

Cxr,
you gave me the code on how I could print the up down sideways, but what if i wanted the program to return a list whose elements are those substrings of the given string?? The string that has the consecutive letters only?

def alpha(s):
    res = ''
    for c in s:
        if c.isalpha(): res+=c
        else: res+=' '
    return res.split()
 
print(alpha('1up2down33sideways77'))

I don't understand the question. The alpha() function DOES return a list of substrings. And what do you mean by consecutive letters?

Please clarify, and please use the "ask a related question" feature. :)

ok, im typing up my questions with more clarity, and i will paste the link here.
thank you

FYI: When you use the "related question" feature I will automatically get an alert, because I answered this question.
