IDLE's editor

To create a Python program, you use:

break statement

To jump to the end of the current loop, you can use the

the F5 key

To run a Python program from IDLE, you use:

IDLE's interactive shell

To test a Python statement, you use:

"My student ID is " + str(123456)

What is the argument of the print() function in the following Python statement? print("My student ID is " + str(123456))

nothing will display

What will be displayed after the following code executes? guess = 19 if guess < 19: print("Too low") elif guess > 19: print("Too high")

the program crashes and an error message is displayed

When an exception occurs while a program is running,

sort sequence

When two strings are compared, they are evaluated based on the ___________________ of the characters in the string.

import the module

Before you can use a standard module like the random module, you need to

via a command prompt

A console application runs

module

A file that contains reusable code is called a

once for each integer in the collection returned by the range() function

A for loop that uses a range() function is executed

is defined outside of all functions

A global variable

inside a function

A local variable is defined

can be used to return a local variable to the calling function

A return statement

an exception

A runtime error is also known as:

a browser

A web application runs through

main()

Consider the following code: def get_username(first, last): s = first + "." + last return s.lower() def main(): first_name = input("Enter your first name: ") last_name = input("Enter your last name: ") username = get_username(first_name, last_name) print("Your username is: " + username) if __name__ == "__main__": main()

How many times will "Hi again!" be displayed after the following code executes? for i in range(0, 12, 2): print("Hi, again!")

change line 4 to: print("The discount on this item is $", round(discount, 2))

Given the following code and its output: discount_rate = .1 item = 89.95 discount = item * discount_rate print("The discount on this item is $", discount)) Output: The discount on this item is $ 8.995000000000001

my_name = "Donny", names = ["Lizzy", "Mike", "Joel", "Anne"]

Given the following code, what is the value of my_name and what does the list consist of after the second statement is executed? names = ["Lizzy", "Mike", "Joel", "Anne", "Donny"] my_name = name.pop()

ages = [22, 35, 24, 4, 17, 28]

Given the following code, what would the list consist of after the second statement? ages = [22, 35, 24, 17, 28] ages.insert(3, 4)

None: Index error

Given the following list, what is the value of ages[5]? ages = [22, 35, 24, 17, 28]

a pass statement

If you want to code an if clause, but you don't want to perform any action, you can code
