LIS4369 (Python) Q1

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

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

You bought 0 widget(s) today.

Consider the following code: num_widgets = 0 while True: choice = input("Would you like to buy a widget? (y/n): ") if choice.lower() == "y": num_widgets += 1 else: break print("You bought", num_widgets , "widget(s).") If the user enters "Y" at the prompt, what does the program print to the console?

The product is 6

For the following code, what will the result be if the user enters 4 at the prompt? product = 1 end_value = int(input("Enter a number: ")) for i in range(1, end_value): product = product * i i += 1 print("The product is ", product)

The product is 24

For the following code, what will the result be if the user enters 4 at the prompt? product = 1 end_value = int(input("Enter a number: ")) for i in range(1, end_value+1): product = product * i i += 1 print("The product is ", product)

1, 3, 6, 10,

For the following code, what will the result be if the user enters 5 at the prompt? sum = 0 end_value = int(input("Enter a number: ")) for i in range(1, end_value): sum = sum + i print(sum, end=", ")

check_num <= 0 or check_num > 1000

Given the following code, select the compound condition that makes sure that the input is an integer greater than 0 and less than 1,000. my_num = input("Enter a number between 1 and 999:") check_num = int(my_num) while _________________________: my_num = input("Try again. The number must be between 1 and 999") check_num = int(my_num)

6

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

5

How many times will "Hi there!" be displayed after the following code executes? num = 2 while num < 12: print("Hi, there!") num += 2

a pass statement

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

before the loop is executed

In a while loop, the Boolean expression is tested

the coding of control structures

Pseudocode can be used to plan

10Peaches, 1peach, Peach, peach

Python will sort the strings that follow in this sequence: Peach peach 1peach 10Peaches

higher precedence than the or operator, but lower precedence than the not operator

The and operator has

multitasking

UNIX and Linux are ____ systems, which allow one user to execute more than one program at a time

multiuser

UNIX/Linux are ____ systems, which let many people simultaneously access and share the resources of a server computer.

Define widget count variable Begin infinite loop Get user input IF user buys widget add 1 to widget count ELSE end loop Display results

num_widgets = 0 while True: choice = input("Would you like to buy a widget? (y/n): ") if choice.lower() == "y": num_widgets += 1 else: break print("You bought", num_widgets , "widget(s).") Which of the following could be a pseudocode plan for the program?
