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

Could somebody explain to me why the code I used to complete this exercise doesn't work.
And how do you send an integer to len?
Thanks

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

This should have worked, but there's one problem. Whenever we're doingsomething like:for line in f:...there can be some interference bet
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.

[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"
