Description

Same root cause as the PEP 758 fix in web_programming/crypto_price_tracker.py (#15550): the script declares requires-python = ">=3.13" in inline metadata but catches exceptions unparenthesized, which only parses on 3.14. On Python 3.13 exactly, loading the script raises SyntaxError before any request runs.

One-line fix, no behavior change on 3.14+.

How I tested

• ty check resolves the preamble version and reports error[invalid-syntax]: Multiple exception types must be parenthesized on Python 3.13 before the change and nothing after.
• ruff check web_programming/instagram_crawler.py passes.
