I'm home for lunch so my email addy is different.
No, it doesn't happen very often, but when I need to reverse something
(usually a list or a string). I can never remember right of the top of
my head how to do so in Python. I always have to Google for an answer or
refer back to old code.
IMO, I should be able to intuitively know how to do this. Python is so
user-friendly most every place else... why can it not be so here?
I wrote this so I'll never have to remember this again:
def invert(invertable_object):
try:
print invertable_object[::-1]
return invertable_object[::-1]
except:
print 'Object not invertable'
return 1
invert([1,2,3,4])
invert('string')
invert({1:2, 3:4})
