Resolving UnicodeDecodeError in Pandas CSV Reading: From Encoding Issues to Compressed File Handling
This article provides an in-depth analysis of the UnicodeDecodeError encountered when reading CSV files with Pandas, particularly the error message 'utf-8 codec can't decode byte 0x8b in position 1: invalid start byte'.
