This is handy for a couple of reasons:
- When you look at these files in 6 months time, you will know in what order you should run them
- When you are running the files, they will autocomplete very easily at the command line (Windows or Linux), e.g. you type "python 0", then hit TAB, and the name of the file will autocomplete. No need to think about the name of the file, (is it calcresults.py or analyseresults.py?) or have the problem of several files which start with the same letter.
