Problem 4 print("Problem 4") Create a function named problem4. Create an empty set of the names of your friends. Ask the user how many friends they would like to add to the set. Using a loop, ask the user for the friend to add. Using a loop, print the elements of the set. ... F +

Topics: User-defined functions, list, string, docstringProblem Statement: This program finds the unique letters from a given string and printsthe unique letters and their count. For example: word ‘LITTLE’ has ‘L’, ‘I’, ‘T’, ‘E’ are theunique letters.Lab Scenario:The program repeats until hits ‘n’. The program takes a user input of a string. The programfinds the unique letters in the string, add them in a list and displays the list and their count.Consider the following important points:1) You need to design a user-defined function named count_unique_letters whichtakes user word as parameter and returns the list of unique letters calledunique_letters in the given word.a. Hint: Iterate over each letter in user word, check if the letter is in the list, if notadd it to the list, otherwise continue to the next letter. A ‘in’ keyword can helpto determine if a character in the unique_letters list.b. You need to write a simple docstring for this function.2) Your program must have a main()…

TODO Create the function add func to complete the following TODO (). Create the add func() function, which accepts two arguments. The function should use the + operator to add the two arguments and then return the result. For instance, 3 should be returned if the arguments' input values are 1 and 2. Likewise, "good day" should be returned if the input arguments are "good" and "day."   # TODO 6.1 print(f"add_func output for 1 + 2: {add_func(1, 2)}") print(f"add_func output for good + day: {add_func('good',' day')}") todo_check([ (add_func(1,2) == 3,'add_func() did not return 3 when using input values 1 and 2.'), (add_func('good',' day') == "good day",'add_func() did not return "good day" when using input values "good" and " day"') ])

program5_1.py Part 1Write a program that displays a table of ten distance equivalents in miles and kilometers. See Example output. You must generate the table by running a function inside a loop in main. Generate a random integer from 10 to 60, inclusive, in each loop cycle. Use this latter value as the miles argument to the function. Repeat: The function prints the table.  Print  the miles in a column 5 characters wide with 2 decimals and the kilometers in a column 13 characters wide with 5 decimals. Use the column formatting concepts at the end of Chapter 2, not tabs or other methods not in this course. Please include your psudocode to explain your code.  Example output MILES   KILOMETERS 52.00     83.68568 11.00     17.70274 40.00     64.37360 21.00     33.79614 14.00     22.53076 23.00     37.01482 48.00     77.24832 22.00     35.40548 15.00     24.14010 16.00     25.74944 program5_2.py Part 2Write another program that generates another table with the same columns and decimals…

Create a string variable containing your full name (with spaces) 2) print the string as shown below 3) Create a blank 5x10 character array 4) Create a function printArray() that will print every row and column of the array 5) Create a function getNextCharacter() that gets passed the name string and returns the next non-blank character. If you have reached the end of the string then continue at the beginning. You may need to use a global variable 6) Create a function fillArray() that will fill the 2 dimensional array with the letters of your name skipping blanks. Use the above getNextCharacter() function to fill the array with only the characters in your last name. 7) Print the entire array. 8) Request a row number to print and use a sentinal loop to make sure the row number is valid. If not then request a row number again 9) Create a function printIter() that prints only the passed row using iteration 10) Create a function printRecur() that prints only the passed row using recursion…

Add a function to get the CPI values from the user and validate that they are greater than 0. 1. Declare and implement a void function called getCPIValues that takes two float reference parameters for the old_cpi and new_cpi. 2. Move the code that reads in the old_cpi and new_cpi into this function. 3. Add a do-while loop that validates the input, making sure that the old_cpi and new_cpi are valid values. + if there is an input error, print "Error: CPI values must be greater than 0." and try to get data again. 4. Replace the code that was moved with a call to this new function. - Add an array to accumulate the computed inflation rates 1. Declare a constant called MAX_RATES and set it to 20. 2. Declare an array of double values having size MAX_RATES that will be used to accumulate the computed inflation rates. 3. Add code to main that inserts the computed inflation rate into the next position in the array. 4. Be careful to make sure the program does not overflow the array. - Add a…

Complete the following Code

*Part A and B important. The functions are just examples.   A. Write a function called getDimension() that asks the user inputs for the dimensions that consists of twovalues: row and column, then return it to the mainline (also known as global scope) of the program. Therange of the dimensions that the user can input is from 4 to 10 for both rows and columns Please referto the gameplay sample. B. Next, use a 2-dimensional list to represent the game board, where each cell can be either empty(represented by a space " "), a token belonging to human (represented by "X"), or a token belonging tocomputer (represented by "O") as shown in Table 1. Write a function called printBoard(board) thattakes a 2-dimensional list representing the game board and prints it to the console   functions: 1) dropToken (board, col, token): takes a 2-dimensional list representing the game board, acolumn number, and a token (either "X" or "O") and returns the row number of the placed token.This function places the…

Please complete the exercise as instructed and do not use global variables. Please follow the guidelines of what the solution cannot use provided in the second picture. Thank you!

Create a function using a "while" loop. The function asks the user to input a number between 10 and 20. If the number is not within the specified limits, the user must change his/her input until he/she enters the correct value.
