Loops and Comprehensions

for, while, range, enumerate and zip, then list comprehensions. The accumulator pattern here is the one you will reuse in every later section.

Learning Objectives

• →Accumulate a result across a loop without resetting or returning early
• →Use range to loop a fixed number of times
• →Get the index and the value together with enumerate
• →Walk two parallel lists with zip
• →Write a list comprehension, with and without a filter
• →Write a while loop that is guaranteed to terminate
