Re: [Numpy-discussion] How to use user input as equation directly

2016-10-27 Thread John Ladasky
This isn't just a Numpy issue. You are interested in Python's eval(). Keep in mind that any programming language that blurs the line between code and data (many do not) has a potential security vulnerability. What if your user doesn't type "x = 2*np.sin(2*np.pi*44100*t+np.pi/2)" but instead

Hi there, I've been using Numpy for several years and appreciate it very much. The following minimal code has been tried on Python 3.4 and 3.5, with Numpy 1.8 and Numpy 1.11, respectively. I want to temporarily change the way that a Numpy array is printed, then change it back. import numpy as
