Answer 1

Lenoname you can use the .isalpha() method and try-except logic.

Answer 2

try-except:

from string import ascii_letters
try:
a = input()
assert all(c in ascii_letters for c in a)

except:
print("Wrong, try again")

isalpha():

a = input()
if a.isalpha():
print("Correct!")
else:
print("Wrong")

Answer 3

isalpha() method or try-except statement, not both

Answer 4

Lenoname ,

what about this:

while not (inp := input()).isalpha():
print("wrong input - try again: ")
print("all chars are letters:", inp)

it does not handle spaces, but this was not mentioned

Answer 5

🇮🇳SATYAPRAKASH🇮🇳 that accomplishes literally nothing. All input is string in python.

Answer 6

try:
a = input()
assert a.isalpha()
print(a)
except:
print("wrong")

Answer 7

take input
while incorrect input:
ask again
if the test is really bulky you might instead wanna do:

while True:
take input
if correct input:
break
else:
complain some to the user
