Why Am I Getting an IndentationError After a Try Block Without an Except Clause?

Unexpected IndentationError after a Try Block with No Except

When attempting to define a function following a try block without an except clause, users may encounter an IndentationError. This arises from the rule in Python that every try block must be accompanied by at least one matching except or finally block.

Code Example

Consider the following code:

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

Error Message

Running this code would result in an IndentationError similar to:

    def second_function(x, y, z):
    ^
IndentationError: unexpected unindent

Reason for the Error

The IndentationError occurs because the Python interpreter expects subsequent code to be indented within the try block since no except or finally block has been defined.

Solution

To resolve this issue, either add an except block after the try block or, if no exception handling is required, use the pass statement:

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

Note: Older versions of Python may report this error as an IndentationError for subsequent code, while newer versions may provide more specific error messages.
