If you have a number and want to have a guess at its possible closed form expressions via CLI.
I'm a lazy lazy man. I don't like manually copying and pasting a number into WolframAlpha via the browser. This allows you to just do this via the terminal.
I find myself doing this often when I am trying to characterize floating point numbers into concise mathematical expressions. If this is you as well, hopefully this helps you as well!
Ideally, create a virtual environment. Then:
pip install requirements.txt
python src/fetch_wolfram/fetch.py 3.14159
which yields
π≈3.1415926535
sqrt(6 ζ(2))≈3.1415926535
π^2/31^(1/3)≈3.14180466
