Python:

Exercise 1: Prompt for Integer Function

• Create a function called PromptForInteger
• The function should return one value - a valid integer (between 1 and 100) that the user entered
• Inside the function, ask the user to enter an integer between 1 and 100 by displaying:
  • "Please enter an integer (1 to 100): "
  • Use the input() function here and provide the string as its parameter
• Read in the input and store it in a variable
• While the user enters invalid values (less than 1 or greater than 100)
  • Print the error "Your response must be from 1 to 100, try again: "
  • Use the input() function here and provide the error message string as its parameter
• Once the user enters a valid value, return that value
• Call the function in the area for Exercise 1 and print the value it returns

Exercise 2: Custom Range

• Modify your PromptForInteger to have four parameters:
  • a minimum value for the integer
  • a maximum value for the integer
  • a string that represents the initial message printed
  • a string that represents the error message printed if an invalid response is received
• Modify your loop in the function to use the minimum and maximum values
• Modify your prompts in the function to use the parameters
• Modify exercise 1 to use this new version of the function
• Call the function four times in the area for Exercise 2 and print the value it returns. Use the following min and max values and messages:
  • -50, 50, "Please enter an integer (-50 to 50): ", "Your response must be from -50 to 50, try again: "
  • 98, 106, "Please enter your temperature (98 to 106): ", "You must be dead, try again (98 to 106): "
  • -25, -1, "Please enter the deduction from your account (-25 to -1): ", "Your response must be from -25 to -1, try again: "
  • 1, 10, "Please enter a menu selection (1 to 10): ", "You must choose 1 to 10, try again: "

Exercise 3: Modifying the Exercise Loop

• Modify the while loop that loops through the exercises to use your PromptForInteger method
• Use the initial prompt and the appropriate error from the 'else' statement as arguments
• There is no need to modify the Exercise 3 area
• This will change the functionality of this system just a little, but the previous exercises should still work!

Exercise 4: Simple Lists

• Create a list with the words "Wallet", "Phone", and "Keys" in it
• Print the list using a single line of code
• Sort the list using sort
• Print the list again
• Print the first item in the list
• Print everything except the first item in the list (hint: slicing...) as a list
• Print the last item in the list (hint: negative index)
• Print the index of "Keys" (hint: index() function)
• Append "Tablet" to the list
• Print the list
• Insert "Glasses" to the list as the second item in the list
• Print the list
• Remove "Phone" from the list
• Print the list
• Reverse the list
• Print the list

Exercise 5: Display List Elements on Demand and Copying Lists

• Create a list of names: "Stan", "Cartman", "Butters", "Kyle", "Kenny"
• Use enumerate() in a loop to display the index of each name followed by a space, followed by the name, on a line by itself, like so:
  • "# name"
  • replace # with the index and name with the actual name from the list
  • ex:
    • 0 Stan
    • 1 Cartman
    • 2 Butters
• Using PromptForInteger, ask the user for the index of an item in the list (hint: base the maximum on the size of the list. what would be the minimum?)
  • message: "Choose a name from the list by number: "
  • error: "You must choose one of the above numbers, try again: "
• Print the name the user selects
  • "You chose name X" where X is replaced by the name
• Make a copy of the list of names
• Print the copy
• Remove Cartman from the original list
• Print the original list
• Print the copy
• Remove Kenny from the copy
• Print the original list
• Print the copy

Exercise 6: Summation

• Using the PromptForInteger and a loop, ask a user to input 10 ints between 1 and 100, store each in a list
  • "Please enter an integer (1 to 100): "
  • "Your response must be from 1 to 100, try again: "
• print the list of numbers
• print the sum of the numbers (hint: use the sum method)
