    The document contains a series of questions about Python functions. It begins by asking which Python keyword indicates the start of a function definition ("def"), how to indicate the end of a function block (by de-indenting), and what the raw_input() feature is best described as (a built-in function). It then provides several code examples and asks what they would print out or return. The questions cover function definitions, arguments, returns, and the main benefit of writing your own functions (avoiding writing the same code more than once).

    x = addtwo(2, 7)
    print x
    addtwo

    9
    Traceback

    Answer: 2

    Question 10
    What is the most important benefit of writing your own

    functions?
    To avoid having more than 10 lines of sequential code without
    an indent or de-indent
    Following the rule that whenever a program is more than 10

    lines you must use a function


    Following the rule that no function can have more than 10

    statements in it
    Avoiding writing the same non-trivial code more than once in

    your program

    Answer: Avoiding writing the same non-trivial code more than

    once in your program
