String Compression and Decompression

A Python command-line practice project for run-length encoding.

The script can:

• compress repeated letters, for example aaabbcccc to 3a2b4c
• decompress count-letter groups, for example 3a2b4c to aaabbcccc
• choose compression or decompression automatically from the first character of the input

Project Files

• compression_decompression.py - contains the DeCompression class and the command-line prompt

How To Run

From the project folder:

python compression_decompression.py

Then enter either plain letters or a compressed count-letter string:

aaabbcccc
3a2b4c

Notes

• Multi-digit counts are supported, such as 12a.
• The current input detection is simple: input starting with a digit is decompressed, and input starting with a letter is compressed.
