So I want to write a program in python that reads each line and
detects which numbers of the second column are the maximum and the

You have an infinite loop. Fortunately your program stops because of the
error. When you encounter end of file, line becomes the empty string and
the split gives you only 1 item instead of 2.
So add
Your regex is not working correctly I guess, I don't even know why you
are using a regex, something like this would work just fine:
import sys
nums = [float(line.split(' -')[1]) for line in open(sys.argv[1])]
print 'min=', min(nums), 'max=', max(nums)
Sorry, that should be line.split() -
