Simplify Single Exception Tuple

Sourcery refactoring id: simplify-single-exception-tuple

Description

Replace length-one exception tuple with exception.

Before

try:
    read_file()
except (FileNotFoundError,) as e:
    log_error(e)
    create_file()

After

try:
    read_file()
except FileNotFoundError as e:
    log_error(e)
    create_file()

Explanation

Python supports catching multiple exception types at once by using tuples. However, when only a single exception type is being handled, there is no need to wrap it in a tuple.

Using the exception type itself makes your code easier to read, and your intent clearer.
