Yahtzee! Yahtzee is a dice game that uses five die. There are multiple scoring abilities with the highest being a Yahtzee where all five die are the same. You will simulate rolling five die 777 times while looking for a yahtzee. Program Specifications : Create a list that holds the values of your five die. Populate the list with five random numbers between 1 & 6, the values on a die. Create a function to see if all five values in the list are the same and IF they are, print the phrase "You rolled ##### and its a Yahtzee!" (note: ##### will be replaced with the values in the list) Create a loop that completes the process 777 times, simulating you rolling the 5 die 777 times, checking for Yahtzee, and printing the statement above when a Yahtzee is rolled. When you complete the project please upload your .py file to the Project 2 folder by the due date.
From the code supplied by the tutor, modify it so that: 1. Ask what kind of animal it is (for example, carnivore, herbivore, and omnivore) When prompting for the information, it is saved in a list for each of the three animal types (for example, lions in carnivores, bears in omnivores, giraffes in herbivores) and they are saved depending on the number that the user adds in each list. 2. At the end, a list of lists is printed that presents the data of each of the saved animals according to their type.
Perform the following. 1) Conver the infix expression a/b-c+d*e-a*c into postfix expression and trace that postfix expression for given data a=6, b=3, c=1, d=2 , e=4 .2) A student is asked to develop an application as part of mini project which reverses the order of numbers, such that the number that is placed last in the list will be removed first. The list can hold any number of elements. Implement the following menu based C++program for the same.
Write the following function that tests whether the list has four consecutive numbers with the same value: def isConsecutiveFour(values):Write a test program that prompts the user to enter a series of integers and reports whether the series contains four consecutive numbers with the same value.
The ListInterface defines two constructors.

Given: a variable current_members that refers to a list, and a variable member_id that has been assigned a value. Write some code that assigns True to the variable is_a_member if the value assigned to member_id can be found in the current_members list. Otherwise, assign False to is_a_member. In your code, use only the variables current_members, member_id, and is_a_member.
Common Time Zones Function Name: commonTimeZones() Parameters: code1( str ) , code2( str ) Returns: list of common time zones ( list ) Description: You and your friend live in different countries, but you figure there's a chance that both of you might be in the same time zone. Thus, you want to find out the list of possible time zones that you and your friend could both be in. Given two country codes, write a function that returns a list of the time zones the two countries have in common. Be sure not to include any duplicate time zones. If the two country codes do not have any common time zones, return the string 'No Common Time Zones' instead. Note: You can assume that the codes will always be valid. example test cases: >>> commonTimeZones('can', 'usa') ['UTC-08:00', 'UTC-07:00', 'UTC-06:00', 'UTC-05:00', 'UTC-04:00'] >>> commonTimeZones('rus', 'chn') ['UTC+08:00'] For this assignment, use the REST countries API…

1. Write the function below per the docstring. def rollUntil3ConsPrimes (): **'Use the random module to roll a fair dice until there have been 3 consecutive prime numbers rolled. The starting score is 100. The final score is the starting score decreased by 5 for every non prime roll made. Returns the list of dice rolls made and the final score as a tuple. Use a while loop and a list accumulator. Use appropriate helper functions - you MUST use at least one helper function. Hint: in the while loop, ue a counter to count the number of consecutive primes rolled by using a counter that increases its count if a prime is rolled, but if a prime is not rolled the counter is set back to zero. .. print('Q1') print('Sample runs:') for i in range(5): Rolls,Score = rolluntil3ConsPrimes () # note how return is received from # a function that returns a tuple print('Rolls made:', Rolls) print('Ending score is:',Score) print() Q1 Sample runs: Rolls made: [5, 2, 2] Ending score is: 100 Rolls made: [4, 3,…
