♦♣♥♠ Challenge 01 - Heads or Tails ♦♣♥♠

Generate the random outcome of flipping a coin using Python. Use the letter 'H' for Heads, and the letter 'T' for Tails.

Your output could look like this:

Or it could look like this:

♦♣♥♠ Challenge 02 - Quit on Tails ♦♣♥♠

Simulate the flipping of the coin until I throw a 'T' (Tails).

Your output could look like this:

It could also look like this:

♦♣♥♠ Challenge 03 - Counting the Flips ♦♣♥♠

Let a user enter an integer that is used to determine the number of coin flips you program will make.

So if the user enters 20, your code will simulate 20 coin flips. At the end of your program, it will display a summary of the frequency of Heads ('H') and Tails ('T') that were flipped.

So when starting your program, you might chose to code it like this:

import random
target_flips = int(input("Enter number of flips: "))
total_flips = 0
#declare any other variables here
    
while total_flips < target_flips:
    #your code here
    total_flips += 1

Your program might look like this when it is run:

Enter number of flips: 11
T

Number of Heads: 6
Number of Tails: 5

♦♣♥♠ Challenge 04 - Five in a Row ♦♣♥♠

Lets see how many flips it takes me to flip 5 Tails ('T') in a row.

When your program runs, it might look like this:

H

♦♣♥♠ Challenge 05 - The Time Game ♦♣♥♠

Add the following functionality to your existing coin flip program:

Ability to target a particular side of the coin ('H' or 'T')
Ability to target the number of flips of the target side in a row, for the program to exit (e.g. 10 'Heads' in a row to exit)
A timer using timeit, to determine how long the program took (see example below)

Here is some source code to help you get started:

import random
import timeit

side_to_target = input("Target Heads or Tails? Enter 'H' or 'T': ")
frequency_to_target = int(input("How many to target in a row: "))

target_reached = False
total_flips = 0
#declare other variables here

#main loop:
timeStarted = timeit.default_timer()
while not(target_reached):
    #...code to process flip
    total_flips += 1

print("Target reached in", total_flips, "flip(s).")
elapsed = timeit.default_timer() - timeStarted
print("Program took " + "{0:.2f}".format(round(elapsed,2)) + " seconds.")
