UnicodeDecodeError: Resolving Encoding Issue in Python

When encountering a "UnicodeDecodeError" related to the 'utf-8' codec, it is crucial to determine the appropriate encoding for the input data. In this scenario, the code attempts to iterate over lines in a file using a "for line in open()..." loop. However, an error occurs when the codec fails to decode bytes within the file.

To resolve this issue, it is necessary to manually specify the correct file encoding. In this particular case, the correct encoding happens to be "ISO-8859-1." By modifying the code to "for line in open('u.item', encoding = "ISO-8859-1"):", the decoding error will be eliminated, and the code will function as intended.
