Tell us what’s happening: You should indent all the lines after shift = 3 so that they become your new function body.

text = ‘Hello Zaira’
shift = 3

def caesar():

alphabet = 'abcdefghijklmnopqrstuvwxyz'
encrypted_text = ''

for char in text.lower():
    if char == '':            
        encrypted_text += char
    else:
        index = alphabet.find(char)
        new_index = (index + shift) % len(alphabet)
        encrypted_text += alphabet[new_index]

print('plain text:', text)
print('encrypted text:', encrypted_text)

Hi there and welcome to our community!

The error message is misleading, but the issue is that this line of code has inadvertently been modified:

You should be comparing char with a space (' ') not an empty string (''). Fix this and your code should pass.
