- ----- SMALL COMPLETE EXAMPLE CODE FOLLOWS -------------
#!/usr/bin/python
# File: test.py
import os,sys
import pylab as PL
import numpy as N
def main():
fig = PL.figure(1)
x = N.arange(120.0)*2*N.pi/120.0
x = PL.resize(x, (100,120))
y = N.arange(100.0)*2*N.pi/100.0
y = N.resize(y, (120,100))
y = N.transpose(y)
z = N.sin(x) + N.cos(y)
PL.imshow( z , cmap=PL.cm.jet)#, interpolation='nearest')
sys.stderr.write("Begun.")
PL.show()
sys.stderr.write("Done.")
sys.exit(0)
if __name__ == "__main__":
- ---- END OF SAMPLE CODE -------------------
Sample output:
- ------- BEGIN --------------
$ ./test.py
Begun.
- ------- COMMENTS: --------------
The image displays.
I click on the X; the image disappears.
Nothing happens in the terminal output.
In the terminal window I type <ctrl>C.
- ------- BEGIN --------------
^CTraceback (most recent call last):
File "./test.py", line 59, in <module>

The same behavior occurs when run from within an interactive session.
