your code have two problems .  
**first** remove \<\> as it is not required.  
**Second** your indentation of your print() is not right. 💪 happy coding.

what should i do now

```auto
text = 'Hello World'

encrypted_text = ''

for char in text.lower():
    if char== ' ':
        encrypted_text+=''
        print('space!')

    index = alphabet.find(char)
    new_index = index + shift
    encrypted_text += alphabet[new_index]

you have missed two level of indentation.  
first after the for loop  
second after the if statement.

Please pay attention! If statement!

1. Remove the \<\> character  
char==’ ’
2. and add space after if and add string symbol ‘’ for space!  
if char==’ ':  
print(‘space!’)

I’ve edited your code for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (`</>`) to add backticks around text.

 ![Pre-formatted-text](https://global.discourse-cdn.com/freecodecamp/original/3X/1/b/1b18854f1059217f29370444396145cc3a0cd8ae.gif)

See [this post](https://forum.freecodecamp.org/t/forum-code-formatting/25574) to find the backtick on your keyboard.  
**Note:** Backticks (`) are not single quotes (').
