File compression tools like
bzip2 can compress text files into a fraction of their size, often to as little as 20% of the original. Data files often come compressed to save storage space and network bandwidth. A typical workflow is to uncompress the file before analysis, but it can be more convenient to leave the file in its compressed form, especially if the uncompressed file would take up a significant amount of space. In this post I'll show how to work directly with compressed files in python.
