Why Does Python Throw an IndentationError Even When the Code Is Properly Indented?

Indentation Error Despite Correct Function Indentation: Why Does It Occur?

In Python, a try block expects a subsequent except or finally block to handle any potential exceptions. Neglecting to include either can lead to an IndentationError. Consider the following code:

<code class="python">def first_function(x):
    try:
        return do_something_else()
def second_function(x, y, z):
    pass</code>

This code triggers an IndentationError on the second_function declaration. Despite the proper indentation using spaces, the error occurs because the try block in first_function lacks a corresponding except or finally block.

In older Python versions, this error was classified as an IndentationError. However, newer versions may report it differently. This error highlights the importance of proper exception handling in Python. Every try block must be followed by at least one except or finally block.

Refer to Python's Errors and Exceptions tutorial for further clarification on this and other exception-related concepts.
