title: using CSV module with readline()
body: <p>Yesterday I posted the below link:
  <a href="https://stackoverflow.com/questions/7181977/python-csv-module-read-and-write-simultaneously">Python CSV Module read and write simultaneously</a></p>
  
  <p>Several people suggested that I "If file b is not extremely large I would suggest using readlines() to get a list of all lines and then iterate over the list and change lines as needed."</p>
  
  <p>I want to still be able to use the functionality of the CSV Module but do what they have suggested.  I am new to python and still don't quite undertand how I should do this.</p>
  
  <p>Could someone please provide me with an example of how I should do this.</p>
