Hi Folks,
I am quite new to python and I don't have a lot of experience with it
yet.
I have two simple questions:
1. Is there a way to limit the number of times a list comprehension will
execute? E.g. I want to read from input only 5 values, so I would like
something like (the values between # # are what I want):
===================================================================================
COUNT = 0
print [ v for v in sys.stdin.readlines() *# *IF COUNT< 5* #* ] ##
Increment
COUNT somewhere
Easiest would be print [ v for v in sys.stdin.readlines()[:5] ] but that
still reads the entire sys.stdin (whatever it may be...)
Use readline() + a counter instead...
print [sys.stdin.readline() for x in xrange(0,5)]
