In order to reduce the size of a long text string, for example, to minimize traffic when sending some text data over the Internet, it can be compressed before sending and unzipped after receiving. The size of transmitted data is significantly reduced in comparison with sending text strings in their original format.

To zip a text string in memory, we can use the “zlib” module.

Let’s use the “compress” function to compress the string. This function takes a byte string as an input parameter and returns the compressed byte string.

As we can see with this simplest example, the line size has been reduced by more than one and a half times.
