List comprehensions are for building lists, not consuming them. If you want to do something with every element in a list, other than building a new list with it, you should be using a for loop. > [print (item + "\n") for item in data] > > But, this doesn't work as the inclusion of the print causes an invalid > syntax error. > > Any thoughts? Don't do this. Perhaps you could share a small piece of code that you think is too slow, and ask for advice in speeding it up? If you're not sure which small pieces of code are too slow, you need to profile your application to find out. See the documentation for python's profile module. If you don't have enough code written to profile, then it's probably too early to be doing these optimizations. -- Jerry _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
