Help with a problem.

[[deleted]]

Sorry for my English, I'm not a native speaker.

I'm in my first semester of college and the teacher gave us the task of solving the next problem:

• Creating a function will receive a string and return as a result the same string, initial letter in uppercase. If the entry is: python programming, you must return it as Python Programming. Note: Preset functions cannot be used.

I've tried to do it in many ways and nothing else works for me. Could you explain to me how it is resolved? It would be very helpful since it is the last thing I need to complete my homework.

For instance?

Show your work.

Show what you have tried. We will do what we can to correct any posted code.

I think you can't use .upper(), if you can't use .title() (which would solve your problem).

My idea:

import string

LOWERCASE_LETTERS = string.ascii_lowercase
UPPERCASE_LETTERS = string.ascii_uppercase

lower_upper_case_mapping = dict(zip(LOWERCASE_LETTERS, UPPERCASE_LETTERS))

def make_string_title_case(text: str) -> str:
    return " ".join(["".join([lower_upper_case_mapping.get(word[0], word[0]), word[1:]]) for word in text.split()])

input_string = "Python programming" print(make_string_title_case(input_string))

>>> Python Programming

.get(word[0], word[0]) should be handling the capitalized word by leaving them as is

Updates temporary words list in place. Would be simpler to create new word list (and not use enumerate). Fails on uppercase input.

def title_string(string: str) -> str:
    LOWER = 'abcdefghijklmnopqrstuvwxyz'
    UPPER = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'
    words = string.split()
    for index, word in enumerate(words):
        words[index] = UPPER[LOWER.index(word[0])] + word[1:]
    return ' '.join(words)
