And a very straightforward, intuitive way of looking at this is this very naive if/else statement. You see two code blocks, both of which contain to print statements, and in the beginning, you see if True and then column. And when you have a column and in the next line, you indent with four spaces, then you're in a new code block. And then the else statement is also a code block. So we have else with a colon and then two lines to print statements that are a code block. Now, code blocks are present in many places in the language, not just if else statements.
