Question

2. . Write the function below per the docstring. A tuple is simply comma separated data. In the function below, the tuple returned are 2 ints. def Htcounts (flips): "Given a list, flips, of H's and T's, returns a tuple of the number of H's and the number of T's, in that order. Uses 2 sum accumulators, one for number of heads, the other of the number of tails. Traverses the list, flips, with a for loop and uses booleans to count the number of heads and of tails.' print('Sample run:') nh, nT = HTcounts (flips) print('For the sample coin toss of 5 coins already made, ') print('the number of heads is', nh, 'and the number of tails is', nt) Sample run: For the sample coin toss of 5 coins already made, the number of heads is 4 and the number of tails is 1 3.. Write code ,so that for each of 4 trials, a coin is tossed 5 times and which prints out the number of H's ands of T's for each of the 4 trials. Uses the function from Q2. [Note - your result will almost certainly be different from my result. Remember, we are simulating tossing coins.] The output should have the same form as the sample run shown below: Sample run: Trial: 1 Coin Toss Result: ['H', 'H', 'T', 'T', 'T'] The number of heads is 2 and the number of tails is 3

Answer 1

Here is the answer of second question
