I'm getting inconsistent responses from the Keyboard interrupt Ctrl+C in interactive python (run in xterm) after plotting from matplotlib.

As expected, when executing Ctrl+C inside ipython2 I get the KeyboardInterrupt message.

However, once I plot anything using matplotlib (specifically matplotlib.pyplot) Ctrl+C will exit the interactive python session, as opposed to exiting the running script in the interactive python session (if there is one).

A primitive example.

import numpy as n
import matplotlib.pyplot as m
x = n.linspace(0,4*n.pi,500)
y = x**2*n.sin(x)

m.plot(x,y)
m.show()

Preferrable behavior would be for Ctrl+C to always only interrupt a running script (if any is running), instead of the interactive python session itself.

    What does "ran any script from ipython2" mean? – user2864740 Aug 11 '14 at 10:22
  • @user2864740 I attempted to edit for clarity. Essentially I meant that phrase as "executing any script I have written (using 'run script.py') from inside an interactive python session". – Abstracted Aug 11 '14 at 10:35

  • If people are still researching this problem (like me) then the links in the comments above suggest the following answer : `m.show(0)` or `m.show(block=Flase)` – champost Aug 31 '16 at 00:55

I did have the same problem for a long time. Try to run ipython with qt:

ipython --matplotlib=qt
