Code the following write a For loop that iterates through a list of products (any number of products) that are sold in a store and prints them. [examples: fan, fridge, freezer, washer, etc.]. b) copy the code from a) and use the same loop to add more products(any)to the list. You must use list methods to add. c) Copy the code from c), and search for a specific product (any), if the product is found the loop is terminated. Make sure to use else in the for loop. d) Create an empty dictionary, then add 4 entries (the key is a word, the value is word’s frequency in a book). [example: {‘street’: 23}]. e) Create a for loop to access the entries from d) and print the keys and values. f) Copy the code from e) and search for a specific key in the dictionary and prints its value. The program prints a message “ the {key} is not found”, if the key does not exist. ..?
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

#in c++ We need to store information about each student in a class of N students. For example, name, student_no, specialization and GPA. Write a menu-driven program that allows the user to enter queries as many times as he wishes. The menu should offer the following options: 1. Add a new student. 2. Update student information using his/her student_no. 3. Get a list of all students with GPA above an input GPA. 4. List all the information about a student using his/her student_no. 5. Delete a student his/her student_no. 6. Quit

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 Program How can I run a program that functions like this: The user will input a word and every character of the word becomes an element in the list. Then, their corresponding position in the alphabet must be printed out. Example Input a word: EGG Output: ['5' , '7' , '7']
The two-dimensional lists m1 and m2 are strictly identical if their corresponding elements are equal. Write a function that returns True if m1 and m2 are strictly identical, using the following header:def equals(m1, m2):Write a test program that prompts the user to enter two lists of integers and displays whether the two are strictly identical.

***python only*** Write a function votes_by_race() which takes a list of dicts as a parameter and returns a dict. For example, given the following list: votes = [{'for': 'A, 'age': 35, 'race': 'w'}, {'for': 'B', 'age': 40, 'race': 'b'}, {'for': 'B', 'age': 20, 'race': 'b'}, {'for': 'A', 'age': 30, 'race': 'a'}, {'for': 'A', 'age': 41, 'race': 'w'}, ] The call votes_by_race(votes) should return the following dict:{"White": 2, 'Black': 2, 'Asian': 1, "Hispanic': 0}
