Checking if input has letters in it

My error appears on this line:

if exclude3 not in Sent:

And it is:

TypeError: 'in <string>' requires string as left operand, not set

My code is:

import string

Word = input("Please give a word from the sentence")

exclude3 = set(string.ascii_letters)

if exclude3 not in Sent:
    print("")
elif exclude3 not in Word:
    print("")
else:

What is a left operand? What am I doing wrong and is there a simpler way to accomplish what I want? Should I be using something other than in and what should that be?

Solution

  • exclude3 is not a string it is a set.
    You try to use the in operator to check if a set is contained in another set which is wrong.

    Maybe you meant to write: if Sent not in exclude3 ?
