2.0

What is the output of the following statement, given that value1 = 2.0 and value2 = 12?print(value1 * value2) a. 24 b. value1 * value2 c. 24.0 d. 2.0 * 12

A Text Editor IDLE

In a print statement, you can set the __________ argument to a space or empty string to stop the output from advancing to a new line. a. stop b. end c. separator d. newLine

End

A local variable can be accessed from anywhere in the program

False

Python allows you to compare strings, but it is not case sensitive

False

Python formats all floating-point numbers to two decimal places when outputting with the print statement

False

The Python language uses a compiler which is a program that both translates and executes the instructions in a high-level language.

False

OneTwoThree

Which type of error prevents the program from running? a. syntax b. human c. grammatical d. logical

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

RAM is a volatile memory used for temporary storage while a program is running.

True

The function header marks the beginning of the function definition.

True

What is the result of the following Boolean expression, given that x = 5, y = 3, and z = 8? x < y or z > x (T/F)

True

What will be displayed after the following code is executed? count = 4 while count < 12: print("counting") count = count + 2

counting counting counting counting

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:

if y >= 10 and 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.

my_function (a = 2, b = 4, c = 6)
