what does it mean when asked about adding space via addition assignment?

Your code so far


# User Editable Region

text = 'Hello World'
shift = 3
alphabet = 'abcdefghijklmnopqrstuvwxyz'
encrypted_text = ''

for char in text.lower():
    if char == ' ':
        encrypted_text += ' '
    index = alphabet.find(char)
    new_index = index + shift
    encrypted_text += alphabet[new_index]
    print('char:', char, 'encrypted text:', encrypted_text)

Hello ankitrao95, welcome to the forum!

It is what you did here:

You are adding a space character to encrypted_text using the += operator.
The += is basically short for: encrypted_text = encrypted_text + ' '.
It’s telling the code, add the following to what was previously there.
