The algorithm scans data to find repeating patterns. Instead of storing the repeated data twice, it replaces subsequent occurrences with a pointer (a pair of numbers: distance and length) to the initial occurrence. import gzip import shutil # Compress with open('data
Pandas can directly read and write compressed files, making it convenient for large datasets. Other Formats How Gzip Compression Works The algorithm
This combination results in a file with a .gz extension, which is often significantly smaller than the original, especially for CSVs, logs, or JSON files. Advantages and Limitations
