Implement the function total_price, which takes in a list of prices of individual products and needs to find the total price. Unfortunately, any product that is priced greater than or equal to $20 has a 50 percent tax, so include that in the final price. Try to do this in one line! Cast your final answer to an integer to avoid floating point precision errors. For example, if x contains your final answer, return int(x)! def total_price(prices): Finds the total price of all products in prices including a 50% tax on products with a price greater than or equal to 20. >>> total_price([5, 20, 30, 7]) 87 |||||| >>> total price ([8, 4, 3]) 15 >>> total_price([10, 100, 4]) 164 |||||| "*** YOUR CODE HERE ***"

Write a function called unroll, which takes in a square array of arrays (i.e. a grid with n rows and n columns). An input could look like this: constsquare=[[1,2,3,4],[5,6,7,8],[9,10,11,12],[13,14,15,16]]; unroll should take in such a square array and return a single array containing the values in the square. You should obtain the values by traversing the square in a spiral: from the top-left corner, move all the way to the right, then all the way down, then all the way to the left, then all the way up, and repeat. For the above example, unroll should return [1, 2, 3, 4, 8, 12, 16, 15, 14, 13, 9, 5, 6, 7, 11, 10].

re Write a program which ends when a user types a user- defined letter. 1. Get an english letter as a sentinal value(a condition of termination). 2. The user will be asked to type an english letter until a user types above sentinel value. Hint: Use char type variables for english letters. e Sample output1: Pick an english letter to terminate: t Type an english letter: y Type an english letter: w Type an english letter: p Type an english letter: h Type an english letter: t Вye. Sample output2: e Pick an english letter to terminate: g Type an english letter: h Type an english letter: g Вye.

Implement a function rollsToRepeat in Python that simulates a dice game in which a pair of dice are rolled repeatedly until some total on the dice occurs the specified number of times. Details: accepts one integer argument, n , the number of repeats required before the game ends rolls a pair of dice repeatedly until some dice total has repeated n times returns the total number of times the pair of dice was rolled For example, using a random seed of 85 , the sequence of rolled pairs will be : (2, 6), (5, 1),(3, 2), (2, 4), (3, 5), (2, 6), (4, 5), (5, 2), (6, 5), (5, 5), ... If you runrollsToRepeat with n=1 , only 1 repeat is required. On the first roll, the total 8=2+6 is repeated once (as wouldany first roll). So the simulation stops and the function returns 1. This always happens whenn=1 . n=2 , some total must repeat twice. This first occurs on the 4throll, when the total of 6occurs for the 2ndtime. n=3 , some total must repeat three times. This first occurs on the 6throll, when…
