Hi,
In the book Python Essential Reference, Chapter 3, when talking about
extended slicing, it gives an example: a = m[0:10, 3:20]. But I
don't understand how the 'm' was defined. What should it looks like?
m could be an instance of the Krayzee class.
py> class Krayzee(object):
... def __getitem__(self, i):
... try:
... r = ['WTF?' for j in i]
... except:
... r = 'WTF?'
... return r
...
py> m = Krayzee()
py> m[1:2:3, 4:5:6]
['WTF?', 'WTF?']
py> m['your moms']
['WTF?', 'WTF?', 'WTF?', 'WTF?', 'WTF?', 'WTF?', 'WTF?', 'WTF?', 'WTF?']
