How to Fix the Python io.UnsupportedOperation: can’t do nonzero end-relative seeks When Use seek() Function

The `io.UnsupportedOperation` error arises when attempting to use the `seek()` function to perform non-zero end-relative seeks on a text file opened in text mode. This restriction stems from the inherent variability in character encoding, making it challenging to determine the exact byte position corresponding to a specific character offset.

How To Read A File Content From The File End (Reverse Reading) In Python

Delving into the realm of file handling in Python, we often encounter the conventional approach of reading content from the beginning of a file. However, situations arise where traversing a file from the end, often referred to as reverse reading, proves more efficient or necessary. This guide delves into the techniques and applications of reverse …
