Compressing data on python
What is a compressed file in Python?
They are special files that can hold the compressed content of many other files, folders, and subfolders.
This makes them pretty useful for transferring files over the internet.

What's the most space-efficient way to compress serialized Python data?
By default, the pickle data format uses a relatively compact binary representation.
If you need optimal size characteristics, you can efficiently compress pickled data.

Create a zlib.compressobj () object, with a wbits value of 31, to select the gzip format. Let's say you call that object gz. Then use gz.compress (data) for each chunk of the.csv you download. Upload the result returned by each gz.compress (data). When the download is complete, upload the result of gz.flush () to complete the compressed data.
In computing, ACE is a proprietary data compression archive file format developed by Marcel Lemke, and later bought by e-merge GmbH.
The peak of its popularity was 1999–2001, when it provided slightly better compression rates than RAR, which has since become more popular.
Searching for patterns in compressed data
In computer science, compressed pattern matching is the process of searching for patterns in compressed data with little or no decompression.
Searching in a compressed string is faster than searching an uncompressed string and requires less space.
