Syntax

A value-returning function is like a simple function except that when it finishes it returns a value back to the part of the program that called it.

True

Computer programs typically perform three steps: input is received, some process is performed on the input, and output is produced.

True

Expressions that are tested by the if statement are called Boolean expressions.

True

IDLE is an alternative method to using a text editor to write, execute, and test a Python program

True

In Python, print statements written on separate lines do not necessarily output on separate lines.

True

Write an if clause to determine whether x is anything other than 10?

if x != 10:

Write an if-else statement that assigns 0 to the variable y if the variable x is less than 10. Otherwise it should assign 99 to the variable y.

if x <10: y = 0 else: y = 99

Write nested decision structures that perform the following: if x is greater than 10 and y is less than 100, display the greater of x and y.

if x > 10 and y < 100: if x > y: print(x) elif y > x: print (y) else: print( ' both values are the same')

Which of the following is the correct if clause to determine whether y is in the range 10 through 50, inclusive? a. if 10 < y or y > 50: b. if 10 > y and y < 50: c. if y >= 10 and y <= 50: d. if y >= 10 or y <= 50:

Write a statement that generate a random number between 1 through 100 and assign it to a variable named rand

import random rand = random.randint(1, 100)

How many numbers of loop iterations will the following code will execute? x = 99 while x > 0: print (x)

it is an example of Infinite loop. No code is written inside the loop that makes the test condition false.

Look at the following function definition : def class_function(a, b, c) d = (a+c) /b print(d) a) Write a function and use keyword argument to pass 2 into a, 4 into b, 6 into c.
