Expected indented block

An expected indented block is a block of code in Python that should be indented to the right of a previous line. Python relies on indentation to determine the scope of code blocks, so it's important to use consistent and correct indentation to avoid syntax errors.

For example, in a conditional statement like this:

if x > 0:
    print("x is positive")
else:
    print("x is non-positive")

The code block after the `if` statement is expected to be indented to the right, while the code block after the `else` statement should be at the same indentation level as the `if` statement. If the indentation is incorrect, Python will raise an `IndentationError`.
