(3 pts) Write the value of each expression on the corresponding line. Make sure to write the correct number type. Assume the following lines of code with the variable declarations have just been executed. (4 pts) i=10j=5k=4 a) i+jk b) i//k c) i/k d) ij Full Name 10. Write the output that will be displayed or the word "error" for the given code and user input. Assume that this is one continuous program. (2 pts) a) num =f float(input("Enter a score: ")) Enter a score: 2.1 print(num*2) b) result =int( num )+ num print(result) 11. Write the output that will be displayed or the word "error" for the given code. ( 3 pts) message = "Lamb Karahi" print( message[ 3:6]) print(message[8:]) i=message.find("a") print(message[:i]) 12. Write the answer to each question or the requested code on the corresponding line. Assume the following lines of code with the variable declarations have just been executed. ( 8 pts) cetaceans = ["blue whale", "dolphin"] marsupials = ["koala", "wombat", "kangaroo"] mammals = marsupials + cetaceans numspecies =[8,20] length = len (mammals) bigone = cetaceans [] critters = mammals [2:3] a) What type of variable is marsupials? b) What type of variable is bigone? c) What type of variable is critters? d) What is the value of length? e) What is the value of bigone? f) Write the code to create a new empty list called primates. g) Write the code to store the number 334 in the second item of numspecies. h) Write the code to remove "dolphin" from cetaceans. 13. What is the sequence generated by the following code? (2 pts) a) range( 3 ) b) range (5,6) 14. What is the output (or error) of the following code? (2 pts) word = "naan" for num in range(1en(word), 1,1 ): print(num, end="^^") 15. The following is a complete program. The program will not run because of syntax errors (over 5 ). Identify 5 errors and how to correct them. Circle your corrections and write on the lines the code you type to fix each one. You will earn 1 point for each error that you correctly identify and 1 point for each correction of the error. (10 pts) print("Multiplication Table" (n) num = input("Please enter a whole number") symbol = " x " for index = range(13): product = index " num msg =" " if index =" " msg = msg + index output(msg, symbol, num, "=", product) print(Math is funl) Corrections 6. Write a program that creates four variables: section, time, prof, and days. Get the values for prof and days from the user by asking for the last name of the professor and the days of the week (MW or TH). Your program should then use branching to set the values of section and time according to the following table. After branching, then print all the information bout the class (see sample run below) using the four variables. No error checking needed. (10 pts) Sample run 17. Write a program that asks the user for words until the user enters a blank line, which is a return with no input (i.e., the empty string). Then the program should print out the longest and the shortest words entered. Use the appropriate loop. Create any variables that you need. No error checking is required (for the user putting two or more words on a line or other weirdness). (10 pts)
