Question 1. Write a function called sum_scores . It should take four arguments, where each argument represents integers corresponding to the team's score for each quarter. It should return the team's total score for that game. (20 Points) Note: Don't overthink this question! In [156]: Opponent Cal 1Q Cal 2Q Cal 3Q Cal 4Q Opp 1Q Opp 2Q Opp 3Q Opp 4Q Nevada 14 0 0 3 0 13 9 0 TCU 6 13 0 13 0 14 7 13 Sacramento State 14 7 14 7 6 0 14 10 Washington 7 3 7 7 7 14 3 7 Washington State 6 0 0 0 14 0 7 0 Oregon 7 0 3 7 3 7 0 14 Colorado 10 13 0 3 0 3 0 0 Oregon State 10 7 14 8 0 10 7 8 Arizona 0 0 3 0 0 0 3 7 Stanford 0 14 13 14 0 3 0 8 UCLA 0 14 0 0 3 14 10 15 USC 3 14 0 7 0 7 0 7 Out[156]: 24 # Just run this cell # Read in the cal_fb csv file games = Table().read_table( "cal_fb.csv" ) games.show() def sum_scores (Q1, Q2, Q3, Q4): '''Returns the total score calculated by adding up the score of each quarter''' return Q1 + Q2 + Q3 + Q4 sum_scores( 14 , 7 , 3 , 0 ) #DO NOT CHANGE THIS LINE 1 2 3 4 1 2 3 4 5

We want to see for a particular game whether or not Cal lost. Write a function called did_cal_lose . It should take one argument: a row object from the final_scores table. It should return either True if Cal's score was less than the Opponent's score, and False otherwise. (20 Points) Note 1 : "Row object" means a row from the table that contains all the data for that specific row. It is not the index of a row. Do not try and call final_scores.row(row) inside of the function. Note 2 : If you're still confused by row objects, try printing out final_scores.row(1) in a new cell to visually see what it looks like! This piece of code is pulling out the row object located at index 1 of the final_scores table and returning it. When you display it in a cell, you'll see that it is not located within a table, but is instead a standalone row object! In [163]: In [164]: Question 4. James wants to see how Cal did against every opponent during the 2021 season. Using the final_scores table: 1. Assign results to an array of True and False values that correspond to whether or not Cal lost. 2. Add the results array to the final_scores table in a column named Results , and assign this to final_scores_with_results . 3. Then, respectively assign the number of wins and losses Cal had to cal_wins and cal_losses . (20 Points) Out[162]: 14 Out[163]: True Out[164]: q1_3 passed! # Just run this cell games.row( 9 ).item( "Cal 4Q" ) def did_cal_lose (row): if row.item( "Cal Score" ) < row.item( "Opponent Score" ): return True else : return False did_cal_lose(final_scores.row( 1 )) #DO NOT CHANGE THIS LINE grader.check( "q1_3" ) 1 2 1 2 3 4 5 6 7 1

In this exercise, you'll practice unrolling a for loop. In the question below, write code that does the same thing as the given code, but with any for loops unrolled. It's a good idea to run both your answer and the original code to verify that they do the same thing. (Of course, if the code does something random, you'll get a different random outcome than the original code!) Optional Question 1. Unroll the code below. In [ ]: In [ ]: Congratulations, you are done with Homework 5! Important submission steps: 1. Run the tests and verify that they all pass. 2. Choose Save Notebook from the File menu, then run the final cell . 3. Click the link to download the zip file. 4. Then submit the zip file to the corresponding assignment according to your instructor's directions. for joke_iteration in np.arange( 3 ): print ( "Knock, knock." ) print ( "Who's there?" ) print ( "Banana." ) print ( "Banana who?" ) print ( "Knock, knock." ) print ( "Who's there?" ) print ( "Orange." ) print ( "Orange who?" ) print ( "Orange you glad I didn't say banana?" ) ... 1 2 3 4 5 6 7 8 9 10 1
