matplotlib - How to close a python figure by keyboard input? -

i'm trying write python program displays figure indefinite time , closes after keyboard key pressed.

in fact, python program should same matlab code:

t = 0:0.01:2; s = sin(2 * pi * t);  plot(t,s)  pause close 

in python i'm able plot figure nothing happens after keyboard input.

import numpy np import matplotlib.pyplot plt  t = np.arange(0.0, 2.0, 0.01) s = np.sin(2*np.pi*t)  #plt.ion() fig = plt.figure() plt.plot(t,s) #plt.show() plt.draw()  raw_input("press key continue.") plt.close(fig) 

so far observed plt.close(fig) not in conjunction plt.show(). however, when use plt.draw() instead, plt.close(fig) closing figure. yet, when add raw_input("press key continue.") program, figure not appear @ all.

what doing wrong?

i tried experimenting plt.ion(), without success.

something maybe ?

import numpy np import matplotlib.pyplot plt  t = np.arange(0.0, 2.0, 0.01) s = np.sin(2*np.pi*t)   fig = plt.figure() plt.plot(t,s) #plt.show() plt.draw() plt.pause(1) # <------- raw_input("<hit enter close>") plt.close(fig)
