Equation parsing in Python
How can I (easily) take a string such as "sin(x)*x^2" which might be entered by a user at runtime and produce a Python function that could be evaluated for any value of x?
equation
Is it possible to plot implicit equations using Matplotlib?
I would like to plot implicit equations (of the form f(x, y)=g(x, y) eg. X^y=y^x) in Matplotlib. Is this possible?
how to handle an asymptote/discontinuity with Matplotlib
When plotting a graph with a discontinuity/asymptote/singularity/whatever, is there any automatic way to prevent Matplotlib from ‘joining the dots’ across the ‘break’? (please see code/image below).
I read that Sage has a [detect_poles] facility that looked good, but I really want it to work with Matplotlib.
Safely evaluate simple string equation
I’m writing a program in which an equation is inputted as a string, then evaluated. So far, I’ve come up with this:
