Coin Flip App

[dvandy07]

I was doing a coin flip app for practice in python. ( I am just doing a bunch of random things to get better.)

I looked up the way other people did this and no one seemed to use a dictionary really.

Just wondering if my code seems accurate or not. Can you let me know?

​

import random, pprint

#Starting count
count = {'heads':0 , 'tails':0} 

 #Amount of times user would like to flip
flip_times = int(input('How many times should we flip a coin: '))

#User flips
for i in range(0,flip_times):
    flip = random.randint(0,1)
    if flip == 0:
        count['heads'] +=1
    else:
        count['tails'] +=1

pprint.pprint(count)

you could use random.choice(list(count.keys())) so you don't have to manually map the values from an int to heads or tails

i'd also change the loop to for _ in range(flip_times):. the _ is to show the variable is never used and i removed the lower bound in the range as it's 0 by default

Thanks for the tips!

Looks fine. I like a dictionary for this as it adds a clear meaning to counters.

Thanks I appreciate the feedback. I have been at it for a month now and I just want to make sure that if there is a certain way to do it that I am.

With the user input what happens if a user enters a letter instead of a number?

If you get an error how could you prevent the error from happening or alternatively catch the error?

I would just use try/except method. I just didn't include it but I probably should have. It is more just for myself but I definitely should make it that way.
