in every example in this you've seen good styling habits the only recommendation pep provides for styling conditional tests is to use single space around comparison operatorssuch as ==>=<for exampleif age is better thanif age< such spacing does not affect the way python interprets your codeit just makes your code easier for you and others to read try it yourse lf - styling if statementsreview the programs you wrote in this and make sure you styled your conditional tests appropriately - your ideasat this pointyou're more capable programmer than you were when you started this book now that you have better sense of how real-world situations are modeled in programsyou might be thinking of some problems you could solve with your own programs record any new ideas you have about problems you might want to solve as your programming skills continue to improve consider games you might want to writedata sets you might want to exploreand web applications you' like to create summary in this you learned how to write conditional testswhich always evaluate to true or false you learned to write simple if statementsifelse chainsand ifelifelse chains you began using these structures to identify particular conditions you needed to test and to know when those conditions have been met in your programs you learned to handle certain items in list differently than all other items while continuing to utilize the efficiency of for loop you also revisited python' style recommendations to ensure that your increasingly complex programs are still relatively easy to read and understand in you'll learn about python' dictionaries dictionary is similar to listbut it allows you to connect pieces of information you'll learn to build dictionariesloop through themand use them in combination with lists and if statements learning about dictionaries will enable you to model an even wider variety of real-world situations
