- printing modelsput the functions for the example print_models py in separate file called printing_functions py write an import statement at the top of print_models pyand modify the file to use the imported functions - importsusing program you wrote that has one function in itstore that function in separate file import the function into your main program fileand call the function using each of these approachesimport module_name from module_name import function_name from module_name import function_name as fn import module_name as mn from module_name import - styling functionschoose any three programs you wrote for this and make sure they follow the styling guidelines described in this section summary in this you learned how to write functions and to pass arguments so that your functions have access to the information they need to do their work you learned how to use positional and keyword argumentsand how to accept an arbitrary number of arguments you saw functions that display output and functions that return values you learned how to use functions with listsdictionariesif statementsand while loops you also saw how to store your functions in separate files called modulesso your program files will be simpler and easier to understand finallyyou learned to style your functions so your programs will continue to be well-structured and as easy as possible for you and others to read one of your goals as programmer should be to write simple code that does what you want it toand functions help you do this they allow you to write blocks of code and leave them alone once you know they work when you know function does its job correctlyyou can trust that it will continue to work and move on to your next coding task functions allow you to write code once and then reuse that code as many times as you want when you need to run the code in functionall you need to do is write one-line call and the function does its job when you need to modify function' behavioryou only have to modify one block of codeand your change takes effect everywhere you've made call to that function using functions makes your programs easier to readand good function names summarize what each part of program does reading series of function calls gives you much quicker sense of what program does than reading long series of code blocks functions
