Algorithms For Dummies

 Getting Started

Sometimes you need to process two lists in parallel. The simplest method of doing 

this is to use the 

zip()

  function.  Here’s  an  example  of  the 

zip()

 function in 

action:

for Value1, Value2 in zip(ListA, ListB):

    print(Value1, '\t', Value2)

This code processes both 

ListA

 and 

ListB

 at the same time. The processing ends 

when the 

for

 loop reaches the shortest of the two lists. In this case, you see the 

following:

Orange  1

Yellow  2

Green   3

Brown   4

This is the tip of the iceberg. You see a host of iterator types used throughout the 

book. The idea is to enable you to list just the items you want, rather than all the 

items in a list or other data structure. Some of the iterators used in upcoming 

chapters are a little more complicated than what you see here, but this is an 

important start.
