</div>List comprehensions are for building lists, not consuming them. If<br>
you want to do something with every element in a list, other than<br>
building a new list with it, you should be using a for loop.<br>

Perhaps you could share a small piece of code that you think is too<br>
slow, and ask for advice in speeding it up? If you're not sure which<br>
small pieces of code are too slow, you need to profile your<br>
application to find out. See the documentation for python's profile<br>
module. If you don't have enough code written to profile, then it's<br>
probably too early to be doing these optimizations.<br>
