- pep look through the original pep style guide at dev/peps/pep- you won' use much of it nowbut it might be interesting to skim through it - code reviewchoose three of the programs you've written in this and modify each one to comply with pep use four spaces for each indentation level set your text editor to insert four spaces every time you press tabif you haven' already done so (see appendix for instructions on how to do thisuse less than characters on each lineand set your editor to show vertical guideline at the th character position don' use blank lines excessively in your program files summary in this you learned how to work efficiently with the elements in list you learned how to work through list using for loophow python uses indentation to structure programand how to avoid some common indentation errors you learned to make simple numerical listsas well as few operations you can perform on numerical lists you learned how to slice list to work with subset of items and how to copy lists properly using slice you also learned about tupleswhich provide degree of protection to set of values that shouldn' changeand how to style your increasingly complex code to make it easy to read in you'll learn to respond appropriately to different conditions by using if statements you'll learn to string together relatively complex sets of conditional tests to respond appropriately to exactly the kind of situation or information you're looking for you'll also learn to use if statements while looping through list to take specific actions with selected elements from list
