I'm very new to python and want to create a basic coin flip program that will repeat based on user input. I was able to create the randomized response for the coin flip but when it asks if I want to repeat it it dosn't generate a new randomized response and instead repeats the same response. how do i get it to restart the program if i input "y".

import random
coin = random.randint(0,1)
y = "y"
n = "n"

import sys
def coin_flip():
    if coin == 0:
        print("Heads")
    elif coin == 1:
        print("tails")
    again = input("flip again?('y' or 'n') ")
    if again == y:
        coin_flip()

    else:
        again == n
        print("good bye")
        sys.exit()
coin_flip()

Your program keep giving you the same result because you are randomizing the value coin variable outside the coin_flip() function. Therefore, it is only being randomized once, at the start of the program.

To fix that, simply randomize the coin variable value at the start of coin_flip() function

def coin_flip():
    coin = random.randint(0,1)
    # the rest of the function

Coin flip program that repeats based on "yes" or "no" response, Coin flip program that repeats based on "yes" or "no" response. what is the most flips you expect to see in order to get 10,000 total heads? code.org flipping coins​  Coin Flipper. This form allows you to flip virtual coins. The randomness comes from atmospheric noise, which for many purposes is better than the pseudo-random number algorithms typically used in computer programs.

You should be generating the random value within the coin_flip function. You only create it at the start of your script, so it is only ever created once.

Move the line coin = random.randint(0,1) to the start of the coin_flip function.

If you dig around a bit in the random module you will find some interesting utilities that will make things like this very short and pretty. For example

random.choice(['Heads', 'Tails']

will give you a random heads or tails without all the extra if/elif logic. These kind of things will make your code easier to read, understand and maintain. For example you could do something like:

import random

while (input("flip again?('y' or 'n') ") == 'y'):
    print(random.choice(['Heads', 'Tails']))
print("good bye")

Coin Flipping is basically a interpretation of a chance outcome as the expression of divine. A coin should always have two sides. In this section, we are going to toss a coin programmatically. We have created a program that can toss a coin over and over until it comes up head 10 times. It should also record the number of tails.

For each toss of the coin the program should print Heads or Tails. Let the program toss the coin 100 times, and count the number of times each side of the coin appears. Print the results. The program should call a separate function flip()that takes no arguments and returns 0 for tails and 1 for heads.

Click on Repeat until you have flipped ten coins. currently, I have 2 core variables one that determines the coins flip another determining the coins height. the flip I've set it to oscillate between the maximum height at which the coin can go and the negative of that as to keep the sprite somewhat in ratio. I have also set the rate at which it flips to the maximum height * 0.1 so the coin won

Comments
  • Holy crap! it worked! I had no idea you had to randomize 'coin' twice, thank you all for the help!
  • The idea is to randomize it every time coin_flip is called, since random.randint() only return an integer value. To be more clear about how it works, you can refer to the documentation.
  • Thanks for the help! I'll definitly have to look into the random module further, the elif statements didn't seem like it wasn't very efficient.
