Hi all
In my program I have a for-loop like this -
>>> for item in x[:-y]:
... [do stuff]
'y' may or may not be 0. If it is 0 I want to process the entire list
'x', but of course -0 equals 0, so it returns an empty list.
In theory I can say
>>> for item in x[:-y] if y else x:
... [do stuff]
But in my actual program, both x and y are fairly long expressions, so
the result is pretty ugly.
Are there any other techniques anyone can suggest, or is the only
alternative to use if...then...else to cater for y = 0?
Thanks for all the replies. A selection of neat ideas for me to choose from.
Much appreciated.
Frank
