input give me incorrect even im writing correct answer

Question

I'm trying to make quiz game but if i answered correct answer it gives me incorrect , is it case sensitive ?

Code :

score = 0
question_n = 0

playing = input('Do you wish to start? (Yes-No)')
if playing == "yes" or playing == "y":
    question_n +=1
    ques = input(f'\n{question_n}. Who owns amazon? ')

    if ques == 'Jeff bezos':
        print('Correct! You got 1 point.')
        score +=1
        print(f'Your score is : {score}')
                 

    else:
        print('Incorrect')
        print(f'The correct answer is --> Jeff bezos. ')
        x = input('Press any key to exit..')
elif playing == "no" or playing == "n":
    print('Thanks for trying me (:')

Error :

Do you wish to start? (Yes-No)yes

1. Who owns amazon? jeff bezos
Incorrect
The correct answer is --> Jeff bezos. 
Press any key to exit..

Yes it's case sensitive. taking some string `s = 'jEfF bEzOs'` and setting `s = s.title()` will set `s = 'Jeff Bezos'` by capitalizing the first letter of every word in your string. — Vin, Jan 23 '23 at 17:45

Yes, comparison of strings is case-sensitive. You could make it case-insensitive by performing the same case modification on both the input string and the comparison string, e.g.:

if ques.upper() == 'Jeff bezos'.upper():
    ...

In the example above, both the user input and the "correct" string are converted to uppercase before comparison. This way, if the user inputs "JeFf BeZoS" and the correct answer is "Jeff bezos", they are both compared as "JEFF BEZOS" and therefore considered equal.

There are functions for working with string cases in Python

str.upper() # convert to upper case
str.lower() # convert to lower case
str.capitalize() # capitalize string
str.title() # capitalize every word in the string (thanks @Vin, I was unaware of this one!)

Examples:

string = 'foo'
print(string.upper())
>>> FOO

string = 'FOO'
print(string.lower())
>>> foo

string = 'foo bar'
print(string.capitalize())
>>> Foo bar

string = 'foo bar'
print(string.title())
>>> Foo Bar

And there's [`casefold`](https://docs.python.org/3.8/library/stdtypes.html#str.casefold), which [can help](https://stackoverflow.com/a/29247821/15032126) with names like Gauß :) — Ignatius Reilly, Jan 23 '23 at 18:23
