I'm trying to make a code that allows only letters. I know we can do this using isalpha() method. But, I'm looking for any other different solutions something like try-except?

That is reinventing the wheel, use str.isalpha

You could use assert and AssertionError

from string import ascii_lettersvalue = None
while True:try:value = input("Give a value: ")assert all(c in ascii_letters for c in value)breakexcept AssertionError:print("Invalid input, try again")print("Valid input:", value)

Give a value: aa!
Invalid input, try again
Give a value: !!!
Invalid input, try again
Give a value: !
Invalid input, try again
Give a value: rrTT
Valid input: rrTT
