[expr for l in f] is a "list comprehension". expr is an _expression_ thatmay involve l.result = [expr for l in f] # is equivalent to:result = []for l in f:result.append(expr)
"list comprehension"

Hi Ben,Yes, that's the point: Python doesn't know when to stop. *grin*
The way we've rewritten the loop:while True:...is an "infinite" loop that doesn't stop unless something in the loop'sbody does something extraordinary, like "breaking" out of the loop.
Python is much dumber than we

This should have worked, but there's one problem. Whenever we're doingsomething like:for line in f:...there can be some interference bet
Being new to programming, I made a text file that contains terms with their definitions that I have come across in my studying. As an exercise, I thought I would make a glossary using a dictionary so I can look up words, add new words, view all entries, etc. I want to enter the words and def

And how do you send an integer to len?

This is an exercise from "How to think like a Computer Scientist."
The following example shows how to use concatenation and a for loop to generate an abecedarian series. "Abecedarian" refers
to a series or list in which the elements appear in alphabetical
order. For example, in Robert McCloskey
