tails_same(number_list:list) -> bool This function should return true if the value at the beginning and the end of the list are equal. False otherwise. Example: number_list = [1, 239, 949, 0, 84, 0, 1] output: True number_list = [1, 239, 949, 0, 84, 0, 13] output: False

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.

Python Qu Write a Python program (not a function!) that asks the user for nonnegative integers,one integer per line.When the user is finished entering their integers, they enter a negative integerto tell the program to stop asking them for more integers.Once the input is complete, the program prints "No integers to average"if the user provided no nonnegative integers,and the average of the nonnegative integers otherwise.You must NOT use lists, tuples, or dictionaries in your code.Here is a sample program run where the user enters 4 and then 8 and then -1.The program outputs Average: 6.048-1Average: 6.0Here is another run where the user types -3 to the first prompt.The program outputs No integers to average-3No integers to average
