Is it possible to avoid integers,floats and special characters using try-except statement only?

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?

>Solution :

That is reinventing the wheel, use str.isalpha

You could use assert and AssertionError

from string import ascii_letters

value = None
while True:
    try:
        value = input("Give a value: ")
        assert all(c in ascii_letters for c in value)
        break
    except 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
