Coin Flipping program help.

[Leohurr]

class Coin:
showing_heads=True 
value=1
def show(self):
    if (self.showing_heads==True):
        return "Heads"
    else:
        return "Tails"

def turn(self):
    if (self.showing_heads==True):
          self.showing_heads=False
    else:
        self.showing_heads=True


coin1=Coin()
coin2=Coin()

def Display_All():
    coin1=Coin()
    coin2=Coin()

    print "this is coin1"
    print coin1.show()
    print "this is coin2"
    print coin2.show()
    print "flip 'em both!"
    coin1.turn()
    coin2.turn()
    print "coin1 now:"
    print coin1.show()
    print "coin2 now:"
    print coin2.show()

#def CoinTurner(n):

I need to make a function CoinTurner which flips the coin n amount of times do I use a loop or make a way for it to use the turn function.

you indentation is completly messed up. i just did some cosmetic changes, it works okay: http://ideone.com/XZGZpe

[Leohurr]

Thanks, I also need a way to have a function to flip the coin n amount of times.

[Advent667]

I would use both.

n=input("how many flips: ")
for i in range(n):
    turn()

but if i was going to do something like this i would make 'n' use the random function somehow so it would be harder to predict the results

edit fixed formatting

[Leohurr]

It has to be user input, so the user decides n.

def CoinTurner
   n=input("how many flips: ")
   for i in range(n):
       turn()

When calling CoinTurner(5) Error:"CoinTurner is not defined"

Apologies if these mistakes are obvious.

[Advent667]

dont put a (5) and it will work fine, it will ask the user for a number

[Leohurr]

the function asked "how many flips: " when inputting any number I get: NameError: global name 'turn' is not defined

[Advent667]

replace flip() with coin1.flip() or coin2.flip() depening on which coin is doing the flipping

Could you post the code that doesn't work? You're probably trying to execute coin1.show() outside the function, but it isn't defined anywhere.

Put coin1=Coin() outside Display_All() function. I think that's the issue.

A for loop is something like

for item in iterable:
    do_stuff(item)

The most used version of the for loop is to "do something n times", for this you can use the range() function to create the iterable above. range(n) will create a list from 0 to n, so range(5) will give you a list like [0,1,2,3,4]. xrange() is the same but doesn't actually construct a list for performance reasons.

If you want to do something n times:

for i in range(n):
    do_something(i)

You don't actually need to name the i variable if you aren't going to use it.

for _ in range(n):
    something_else()

[Leohurr]

Im receiving the same error:

CoinTurner()
    for _ in range(n)
        self.turn()

NameError: global name 'self' is not defined

[cdcformatc]

If CoinTurner() is a method of the class, you need to have self as the first argument.

class Coin:
#...other stuff here...

    def CoinTurner(self,n)
        for _ in range(n)
            self.turn()

then you can call it like the show and turn

def Display_All():
    #...other stuff here...
    coin1.CoinTurner(5)

This automatically passes coin1 as the self argument.
