Python Passing-By-Reference vs. Passing-By-Value - Notesformsc
This is known as passing by value (there is another technique, passing by reference, which we shall not explore). It is important to note that the variables r1, r2 and rp are local to the function, that is, they are distinct from another variable that might be named r1 or r2 in another part of your program (or in another function).

Python avoids this problem by insisting that you make all references to class variables explicit. Bound and Unbound Methods As we saw in Chapter 14, functions are objects that can be assigned to a variable, saved in a list item, passed via a function argument, or anything else you can do with a variable.

To create a function, write its definition. The keyword def is used before a function name, followed by parentheses and a colon. Here is the general format of a function definition in Python: def function_name(): statement. statement. etc. Calling a function is done in order to make the module execute. The general format is: function_name()

To make sure you understand how Python returns results (if you have not already done this), define the cube(x) function into the Python shell; then call it with the code below. On paper, trace the values of variables answer and x inside cube(x) and of variables answer, result in the code snippet.

Step 4: Under the documentation for declaring variables, declare your variables and initialize them to 0. The array/list should be declared as follows: pints = [0] * 7. Step 5: Write a function call to the getPints function and pass it pints. The function will return pints, so set it equal to the function call. This should be done as follows:

Step 5: Under your function definition, write a statement that allows the user to enter their name. Inside of the main function, call inputName() and write a print statement that displays the name. Your code might look as follows: #This program uses functions and variables. #the main function. def main(): print 'Welcome to the variable program'

In Python, they are usually referred to as . functions. Functions. A function is a collection of instructions that is given a name. A function should perform a single task, like initializing the variables in a program, or loading the program's content. If you have two distinct tasks to perform, you probably need two separate functions.
