Using try/except, if/else, or match/case makes the code messy and error-prone. Simple solution: Before processing, convert all keys to lowercase. It’s fast and easy to maintain: data = {k.lower(): v for k, v in original_data.items()} Now you can just use data['ttien'], data['tthue'] without writing long code. ...
