The code I provided is generally a better approach for checking if a file is empty, because it directly checks for an empty file without reading all lines. Here’s why it’s more efficient:

Comparison
Memory Usage:

Original Code (len(input_file.readlines())): This code reads all lines in the file into memory as a list, which can consume a lot of memory if the file is large.
Suggested Code (file.read().strip() == ''): This only reads enough to check if the file has any non-whitespace content. It is generally more efficient, as it doesn’t store data in memory as a list.
