What is a function?
A function is a group of statements that exist within a program for the pur-
pose of performing a specific task.
What is meant by the phrase "divide and conquer"?
A large task is divided into several smaller tasks that are easily performed.
How do functions help you reuse code in a program?
If a specific operation is performed in several places in a program, a function
can be written once to perform that operation and then be executed any time
it is needed
How can functions make the development of multiple programs faster?
Functions can be written for the common tasks that are needed by the different
programs. Those functions can then be incorporated into each program that
needs them.
How can functions make it easier for programs to be developed by teams of
programmers?
When a program is developed as a set of functions in which each performs an
individual task, then different programmers can be
assigned the job of writing
different functions.
A function definition has what two parts?
A function definition has two parts: a header and a block. The header indicates
the starting point of the function, and the block is a list of statements that
belong to the function.
5.7 What does the phrase "calling a function" mean?
To call a function means to execute the function.
5.8 When a function is executing, what happens when the end of the function's block
is reached?
When the end of the function is reached, the computer returns back to the
part of the program that called the function, and the program resumes
execution that point.
5.9 Why must you indent the statements in a block?
Because the Python interpreter uses the indentation to determine where a
block begins and ends
5.10 What is a local variable? How is access to a local variable restricted?
A local variable is a variable that is declared inside a function. It belongs to
the function in which it is declared, and only statements in the same function
can access it.
5.11 What is a variable's scope?
The part of a program in which a variable may be accessed
5.12 Is it permissible for a local variable in one function to have the same name as a
local variable in a different function?
Yes, it is permissible.
What are the pieces of data that are passed into a function called?
Arguments
5.14 What are the variables that receive pieces of data in a function called?
Parameters
5.15 What is a parameter variable's scope?
A parameter variable's scope is the entire function in which the parameter is
declared.
5.16 When a parameter is changed, does this affect the argument that was passed into
the parameter?
No, it does not.
5.17 The following statements call a function named show_data . Which of the
statements passes arguments by position, and which passes keyword arguments?
a. show_data(name="Kathryn", age = 25)
b. show_data('Kathryn', 25)
a.
passes by keyword argument
b. passes by position
5.18 What is the scope of a global variable?
The entire program
5.19 Give one good reason that you should not use global variables in a program.
Here are three:
• Global variables make debugging difficult. Any statement in a program
can change the value of a global
variable. If you find that the wrong value
is being stored in a global variable, you have to track down every statement
that accesses it to determine where the bad value is coming from. In a
program with thousands of lines of code, this can be difficult.
• Functions that use global variables are usually dependent on those variables.
If you want to use such a function in a different program, you will most
likely have to redesign it so it does not rely on the global
variable.
• Global variables make a program hard to understand. A global variable
can be modified by any statement in the program. If you are to understand
any part of the program that uses a global variable, you have to be aware
of all the other parts of the program that access the global variable.
5.20 What is a global constant? Is it permissible to use global constants in a program?
A global
constant is a name that is available to every function in the program.
It is permissible to use global constants. Because their value cannot be
changed during the program's execution, you do not have to worry about
its value being altered.
5.21 How does a value-returning function differ from the void functions?
The difference is that a value returning function returns a value back to the
statement that called it. A simple function does not return a value.
5.22 What is a library function?
A prewritten function that performs some commonly needed task
5.23 Why are library functions like "black boxes"?
The term "black box" is used to describe any mechanism that accepts input,
performs some operation (that
cannot be seen) using the input, and produces
output.
5.24 What does the following statement do?
x = random.randint(1, 100)
It assigns a random integer in the range of 1 through 100 to the variable x .
5.25 What does the following statement do?
print(random.randint(1, 20))
It prints a random integer in the range of 1 through 20.
5.26 What does the following statement do?
print(random.randrange(10, 20))
It prints a random floating-point number in the range of 0.0 up to, but not
including, 1.0.
5.27 What does the following statement do?
print(random.random())
It prints a random floating-point number in the range of 0.0 up to,
but not
including, 1.0.
5.28 What does the following statement do?
print(random.uniform(0.1, 0.5))
It prints a random floating-point number in the range of 0.1 through 0.5.
5.29 When the random module is imported, what does it use as a seed value for random
number generation?
It uses the system time, retrieved from the computer's internal clock.
5.30 What happens if the same seed value is always used for generating random
numbers?
If the same seed value were always used, the random number functions
would always generate the same series of pseudorandom numbers.
5.31 What is the purpose of the return statement in a function?
It returns a value back to the part of the program that called it
5.32 Look the following function definition:
def do_something(number):
return number * 2
a. What is the name of the function?
b. What does the function do?
c. Given the function definition, what will the following statement display?
print(do_something(10))
a) do_something
b) It returns a value that is twice the
argument passed to it.
c) 20
5.33 What is a Boolean function?
A function that returns either True or False
5.34 What import statement do you need to write in a program that uses the math module?
import math
5.35 Write a statement that uses a math module function to get the
square root of 100
and assigns it to a variable.
square_root = math.sqrt(100)
5.36 Write a statement that uses a math module function to convert 45 degrees to
radians and assigns the value to a variable.
angle = math.radians(45)

In mathematics, the notation n! represents the factorial of the nonnegative integer n . The factorial of n is the product of all the nonnegative integers from 1 to n. For example, $$ 7 ! = 1 times 2 times 3 times 4 times 5 times 6 times 7 = 5,040 $$ $and$ $4 ! = 1 times 2 times 3 times 4 = 24$$Write a program that lets the user enter a nonnegative integer and then uses a loop to calculate the factorial of that number. Display the factorial.

What is the return value for a function that has no return statement defined quizlet?
What is the return value for a function that has no return statement defined? The function will return a special value of None.What statement do you have to have in a value returning function?
To return a value from a function, you must include a return statement, followed by the value to be returned, before the function's end statement. If you do not include a return statement or if you do not specify a value after the keyword return, the value returned by the function is unpredictable.How does a value returning function differ from the void function?
Void functions are created and used just like value-returning functions except they do not return a value after the function executes. In lieu of a data type, void functions use the keyword "void." A void function performs a task, and then control returns back to the caller--but, it does not return a value.What is the purpose of an if statement quizlet?
"if" statement is a construct that enables a program to specify alternative paths of execution. one-way if statement executes an action if and only if the condition is true. an if-else statement decides the execution path based on whether the condition is true or false.
