Make sure you provide comments including the file name, your name, and the date at the top of the file you submit. Also make sure to include appropriate docstrings for all functions. The names of your functions must exactly match the names given in this assignment. The order of the parameters in your parameter list must exactly match the order given in this assignment. All loops in your functions must be while loops. If you've been reading ahead, you may have discovered lists and conclude that a list may be the key to solving one or more of the problems below. That would be an incorrect
- 2. conclusion; don't use lists in this programming assignment. While we're talking about things you should not use, do not use the Python functions sum, min, or max. Please note that in all problems, the goal is to give you practice using loops, not finding ways to avoid them. Every solution you write for this assignment must make appropriate use of a while loop. For any given problem below, you may want to write additional functions other than those specified for your solution. That's fine with us. One other thing: if you haven't already done so, or even if you have, go to our Course Information page on SmartSite and read the section on Academic Misconduct. Submitting other people's work as your own, including solutions you may find on the Internet, is not permitted and will be referred to Student Judicial Affairs. Problem 1 Create a Python function called sumOfOdds which takes one argument, an integer greater than or equal to 1, and returns the result of adding the odd integers between 1 and the value of the given argument (inclusive). This function does not print. You may assume that the argument is
- 3. valid. Here are some examples of how your function should behave: >>> sumOfOdds(1) 1 >>> sumOfOdds(2) 1 >>> sumOfOdds(3) 4 >>> sumOfOdds(4) 4 >>> sumOfOdds(5) 9 >>> sumOfOdds(100) 2500 >>> sumOfOdds(101) 2601 >>> Problem 2 Create a Python function called productOfPowersOf2 which takes two arguments, both of which are non-negative integers. For purposes of this problem, let's call the first argument exp1 and the second argument exp2. Your function should compute and return (not print) the
- 4. product of all powers of 2 from 2exp1 to 2exp2. Here are some examples of how your function should behave: >>> productOfPowersOf2(0,0) 1 >>> productOfPowersOf2(1,1) 2 >>> productOfPowersOf2(1,2) 8 >>> productOfPowersOf2(1,3) 64 >>> productOfPowersOf2(1,4) 1024 >>> productOfPowersOf2(1,5) 32768 >>> productOfPowersOf2(2,4) 512 >>> productOfPowersOf2(3,12) 37778931862957161709568 >>> Problem 3 Create a Python function called printAsterisks that expects one argument, a nonnegative integer, and prints a row of asterisks, where the number of asterisks is given by
- 5. the value passed as the argument. Control the printing with a while loop, not with a construct that looks like print("*" * n). This function does not return any value. Here are some examples of how your function should behave: >>> printAsterisks(1) * >>> printAsterisks(2) ** >>> printAsterisks(3) *** >>> printAsterisks(4) **** >>> printAsterisks(0) >>> Problem 4 Create a Python function called printTrianglthat expects one argument, a nonnegative integer, and prints a right triangle, where both the height of the triangle and the width of the base of the triangle are given by the value passed as the argument. This function does not return any value. Your function should use your solution to Problem 3 in printing the triangle. Here are some examples of how your function should behave:
- 6. >>> printTriangle(4) * ** *** **** >>> printTriangle(3) * ** *** >>> printTriangle(2) * ** >>> printTriangle(1) * >>> printTriangle(0) >>> Problem 5 Create a function called allButMax that expects no arguments. Instead, this function gets its input from the user at the keyboard. The function asks the user to enter a series of numbers greater than or equal to zero, one at a time. The user types end to indicate that
- 7. there are no more numbers. The function computes the sum of all the values entered except for the maximum value in the series. (Think of this as dropping the highest homework score from a series of homework scores.) The function then both prints the sum and returns the sum. You may assume the user inputs are valid: they will either be a number greater than or equal to zero, or the string end. Here are some examples of how your function should behave: >>> allButMax() Enter next number: 20 Enter next number: 30 Enter next number: 40 Enter next number: end The sum of all values except 50.0 >>> allButMax() Enter next number: 1.55 Enter next number: 90 Enter next number: 8.45 Enter next number: 2 Enter next number: end
- 8. The sum of all values except 12.0 >>> x = allButMax() Enter next number: 3 Enter next number: 2 Enter next number: 1 Enter next number: end The sum of all values except >>> print(x) 3.0 >>> allButMax() Enter next number: end The sum of all values except 0 for the maximum value is: 50.0 for the maximum value is: 12.0 for the maximum value is: 3.0 for the maximum value is: 0 Problem 6 Create a function called avgSumOfSquares that expects no arguments. Instead, this function gets its input from the user at the keyboard. The function asks the user to enter a series of numbers, one at a time. The user types end to indicate that there are no more numbers. The function computes the average of the sum of the squares of all the values
- 9. entered. For example, given the values 6, -3, 4, 2, 11, 1, and -9, the sum of the squares would be (36 + 9 + 16 + 4 + 121 + 1 + 81) = 268. The average of the sum of squares would then be 268/7 = 38.285714285714285.The function then prints the average of the sum of the squares and returns that average. However, if end is entered before any values are entered, the function notifies the user that no numbers were entered and returns None. You may assume the user inputs are valid: they will either be a number or the string end. Here are some examples of how your function should behave: >>> avgSumOfSquares() Enter next number: 6 Enter next number: -3 Enter next number: 4 Enter next number: 2 Enter next number: 11 Enter next number: 1 Enter next number: -9 Enter next number: end The average of the sum of the squares is: 38.285714285714285
- 10. 38.285714285714285 >>> avgSumOfSquares() Enter next number: 3.27 Enter next number: -1.9 Enter next number: 6 Enter next number: -1 Enter next number: end The average of the sum of the squares is: 12.825725 12.825725 >>> avgSumOfSquares() Enter next number: end No numbers were entered. >>> x = avgSumOfSquares() Enter next number: end No numbers were entered. >>> print(x) None >>> x = avgSumOfSquares() Enter next number: -1 Enter next number: 2 Enter next number: -3
- 11. Enter next number: end The average of the sum of the squares is: 4.666666666666667 >>> print(x) 4.666666666666667 Where to do the assignment You can do this assignment on your own computer, or in the labs. In either case, use the IDLE development environment -- that's what we'll use when we grade your program. Put all the functions you created in a file called "prog4.py". Submitting the Assignment We will be using SmartSite to turn in assignments. Go to SmartSite, go to ECS 010, and go to Assignments. Submit the file containing your functions as an attachment. Do NOT cut-and-paste your functions into a text window. Do NOT hand in a screenshot of your functions' output. We want one file from you: "prog4.py". Saving your work If you are working in the lab, you will need to copy your program to your own flash-drive or save the program to your workspace on SmartSite. To save it on flash-drive, plug the flash-drive into the computer (your TAs or the staff in the labs can help you figure out
- 12. how), open the flash-drive, and copy your work to it by moving the folder with your files from the Desktop onto the flash-drive. To copy the file to your SmartSite workspace, go to Workspace, select Resources, and then use the Add button next to "MyWorkspace".
