# Take character
ch = input("Enter a character: ")

# Check type
if ch.isalpha():
    print("Letter")
elif ch.isdigit():
    print("Digit")
else:
    print("Neither")

Output

Enter a character: a
Letter

Enter a character: 5

Enter a character: @

Use string methods to check character type.

isalpha(): checks if letter
isdigit(): checks if digit
Otherwise: special character
