![]() ![]() The keyword ' def' introduces a function definition. Return (first + sum(rests)) / (1 + len(rests)) ![]() Let's make a program using a function to make the average of any quantity of numbers. They are the most basic structure of a program, and so Python provides this technique for code re-use. Functions prove to be a useful tool when the operations are coded in it and can be used in a variety of scenarios.įunctions are an alternative method of cutting-and-pasting codes rather than typing redundant copies of the same instruction or operation, which further reduces the future work for programmers. Functions also let programmers compute a result-value and give parameters that serve as function inputs that may change each time the code runs. In simple words, Python functions are techniques used to combine a set of statements within a program. They act like a pack of instructions that is invoked by a name. To group a set of statements, programmers use functions, and they can be run more than once in a program. Using a ' def' statement for defining a function is the corner store of a majority of programs in Python.
