4.19 LAB: Golf scores Golf scores record the number of strokes used to get the ball in the hole. The expected number of strokes varies from hole to hole and is called par (possible values: 3, 4, or 5). Each score's name is based on the actual strokes taken compared to par: "Eagle": number of strokes is two less than par "Birdie": number of strokes is one less than par "Par": number of strokes equals par "Bogey": number of strokes is one more than par Given two integers that represent the number of strokes used and par, write a program that prints the appropriate score name. Print "Error" at the end of the output if par or score is not in the expected range. Ex: If the input is: 3 4 the output is: Par 4 in 3 strokes is Birdie

4.23 LAB: Golf scores Golf scores record the number of strokes used to get the ball in the hole. The expected number of strokes varies from hole to hole and is called par (i.e. 3, 4, or 5). Each score's name is based on the actual strokes taken compared to par: • "Eagle": number of strokes is two less than par • "Birdie": number of strokes is one less than par • "Par": number of strokes equals par • "Bogey": number of strokes is one more than par Given two integers that represent par and the number of strokes used, write a program that prints the appropriate score name. Print "Error" if par is not 3, 4, or 5. Ex: If the input is: 4 3 the output is: Birdie
5.7 LAB: Palindrome A palindrome is a word or a phrase that is the same when read both forward and backward Examples are: bob, sees, or never odd or even (ignoring spaces). Write a program whose input is a word or phrase, and that outputs whether the input is a palindrome Ex: If the input is: bob the output is: bob is a palindrome Ex: If the input is: bobby the output is: bobby is not a palindrome Hint: Start by removing spaces. Then check if a string is equivalent to it's reverse. 450052196680037 LAB ACTIVITY 5.7.1: LAB: Palindrome 1 word=input("Enter a word or phrase: ").strip().lower 2 3 without_space= word.replace("","") 4 5 if without_space=without_space[::-1]: print (word, "is a palindrome") print (word, "is not a palindrome") 6 7 8 9 main.py else: I 0/10 Load default template...
12.35 A U-V flip-flop behaves as follows: If UV = 00, the flip-flop does not change state. If UV = 10, the flip-flop is set to Q = 0. If UV 11, the flip-flop changes state. The input combination UV = 01 is not allowed. (a) Give the characteristic (next-state) equation for this flip-flop. (b) Complete the following table, using don't-cares where possible. Q Q+ U V 00 0 1 1 0 1 1 (c) Realize the following next-state equation for Q using a U-V flip-flop: Q+ = A + BQ. Find equations for U and V.

8.27 LAB: Scrabble points Scrabble is a word game in which words are constructed from letter tiles, each letter tile containing a point value. The value of a word is the sum of each tile's points added to any points provided by the word's placement on the game board. Write a program using the given dictionary of letters and point values that takes a word as input and outputs the base total value of the word (before being put onto a board). Ex: If the input is: PYTHON the output is: 14 python tile_dict = { 'A': 1, 'B': 3, 'C': 3, 'D': 2, 'E': 1, 'F': 4, 'G': 2, 'H': 4, 'I': 1, 'J': 8, 'K': 5, 'L': 1, 'M': 3, 'N': 1, 'O': 1, 'P': 3, 'Q': 10, 'R': 1, 'S': 1, 'T': 1, 'U': 1, 'V': 4, 'W': 4, 'X': 8, 'Y': 4, 'Z': 10 }
1.21 LAB: Divide by x Write a program using integers user_num and x as input, and output user_num divided by x three times. Ex: If the input is: 2000 2 Then the output is: 1000 500 250 Note: In Python 3, integer division discards fractions. Ex: 6 // 4 is 1 (the 0.5 is discarded). 413636.2659204x37
