Iteration
from The Computing Zone
Follow this link to hand in your files.
You will need to save each of the tasks in this set in its own file, with a simple naming system:
- 13. Lines cheat should be in a file named
ex13.py,- 14. Cricket over should be in a file named
ex14.pyand so on.
You will be submitting these files to a system which will mark them automatically. Since they’ll be marked by a computer, and computers are terminally stupid, you will need to make sure that your files are labelled correctly, or the computer will assume you haven’t done that particular exercise. You will also need to make sure your output exactly matches the examples, down to capitalisation, spelling, line breaks and spaces.
You need to make sure each of your exercises uses this code layout. Replace the included example (which is exercise 2 from the sequence section) with your code.
def ex(input,print): # your program goes below here # vvvvvvvvvvvvvvvvvvvvvvvvvvvv print("What is your first name?") fname = input("> ") print("What is your surname?") sname = input("> ") print(f"{sname} {fname}") # ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ # your program goes above here if __name__ == "__main__": ex(input,print)
A naughty pupil has been given lines to copy as a punishment from their Computing teacher. The have been asked to type out “I must not behave like muppet in class” 20 times. Write a program that asks a pupil to enter a sentence. The same sentence should then be displayed 20 times.
What sentence would you like copied?
> I must not behave like a muppet in class.
I must not behave like a muppet in class.
I must not behave like a muppet in class.
I must not behave like a muppet in class.

In cricket a bowler bowls 6 balls at a time. This is called an over. Each ball bowled may be hit by the batter who may score some runs. Write a program that allows the runs from an over to be entered (for example: 0, 2, 0, 0, 4, 6). The total scored in that over should then be displayed.
Please enter the runs for each ball:
> 0
> 2
> 0
> 0
> 4
> 6
This over's score was 12.
The naughty pupil forgot to hand their lines in and now has more to do. Adapt program 13 to allow the pupil to select how many lines the program produces.
What sentence would you like copied?
> I must not behave like a muppet in class.
How many times would you like it copied?
> 7
I must not behave like a muppet in class.

The following year the three friends recruit many more charity raisers. Adapt program 11 to repeatedly ask for the next amount of money raised. If the user types a number, that number is added to the total and the program asks again. If the user just presses Enter, with nothing else, the program stops asking and displays the total raised, including the doubled value if appropriate.
Enter the total raised by each person:
> 238
> 624
> 546
> 333
> 651
> 174
>
A total of $2566 was raised.
This will be increased to $4566.
The program should give the user an error message if they enter the wrong password. A message “Entry gained!” should be displayed when the password is entered correctly.
Please enter the password.

> sesame
Entry gained!
You have money to spend on your birthday. Write a program that will ask you what you have to spend, and then to enter the price of each present you want until your total reaches or is over the amount you started with. The program should produce the output shown.
How much money did you get?
> 200
You have $200.
Price of next item:
> 35
You have $165.
Price of next item:
> 100
You have $65.
Price of next item:
> 50
You have $15.
Price of next item:
> 45
You have overspent!
You can't afford the $45 item.
How much money did you get?
> 48
You have $48.
Price of next item:
> 48
You have spent all $48!
A game is created where a user is required to guess an unknown number between 1 and 100 (inclusive). Each time the user guesses the program informs them if their guess is too high, too low or correct. The guessing game only finishes when the user’s guess matches the unknown number.
I'm thinking of a number between 1 and 100.
Which number do you think it is?
45
Your guess is too low. Try again.
86
Your guess is too high. Try again.
67
Your guess is too high. Try again.
50
Your guess is too low. Try again.
54
Your guess is too high. Try again.
52
Correct! I was thinking of 52.
