I enjoy using the interactive Python console as a calculator, but typing
python3 and then
from math import * was annoying. So I scripted it into a simple command I've named
cpy. Maybe someone else can use it.
#!/usr/bin/env python3 import code import readline import rlcompleter # Directly import all the math functions from math import * print("Interactive Python 3 with 'from math import *'") vars = globals() vars.update(locals()) readline.set_completer(rlcompleter.Completer(vars).complete) readline.parse_and_bind("tab: complete") shell = code.InteractiveConsole(vars) shell.interact()
The list of functions available in the Python3 math library . The script is also available as a Github Gist.
