In Python, why is a space sometimes considered an error?

Hi Luna,

In Python, spaces at the start of a line matter because Python uses indentation to understand code blocks.

So if you add extra spaces before a line like print("Hello") when it is not inside an if, for, while, or a function, Python thinks you are starting a block and throws an indentation error.

Example of correct indentation:

if True:
    print("Hello")
