Question

Hello.how to recognize if a letter is small or large in a string without using ord or commands like upper and lower?
I want to convert a sentence like this:
hsiW You ereW ereH
To this:
Wish You Were Here
Without using those commands.

Answer 1

Marjaf ,

(first of all upper() and lower() are not commands but methods of the string class)

lo_ltr = "abcdefghijklmnopqrstuvwxyz"
# iterate through the input string with a for loop
# then check if the letter is in lo_ltr. if True, letter is lower, if False, letter is upper

Answer 2

U can check via ASCII value small letter and capital letters have different different ascii range u can use them

Answer 3

Marjaf exactly you have use if condition with for loop if you characters will be match then u can return true or false or give whatever u want

Answer 4

if 'a' <= letter <= 'z': # check if letter is lowercase
....
Or
import string

if letter in string.ascii_lowercase:
....
Works same for uppercase.

Answer 5

There is islower() and isupper() methods from class `str` that you can use to check whether a string/char was of lower or upper case.

Answer 6

Inactive unfortunately I can't use ASCII Code.

Answer 7

Try the .title() function..

C = "some text"
Print(c.title())

#Output Some Text
