Choosing a language.
WHEN PYTHON SUITS
Automating something you currently do by hand Processing files or data in volume Building an internal tool Connecting two systems Analysis beyond what a spreadsheet handles
WHEN SOMETHING ELSE MAY SUIT BETTER
A website built on an established platform, where existing software does the job Work inside a browser, which needs JavaScript A task a spreadsheet already handles adequately
THAT LAST POINT
Do not write a program to replace a spreadsheet that works.
WHAT TO ASK BEFORE STARTING
Does something already exist that does this? Who will maintain it? What happens when that person is unavailable?
THAT SECOND QUESTION
The one that decides whether a custom script is an asset or a liability.
WHAT TO PREFER
Established software, where it exists A short script, where it does not
WHAT TO AVOID
Building something substantial with no plan for maintaining it.
WHAT MAKES PYTHON A SAFE CHOICE
It is widely known, so someone else can take it over.
