Hello,

I want to total up a variable that changes every time a function is run.

```
import random
def flip():
h,t = 0,1
cheads, ctails, = 0,0
cflips = random.choice((0,1))
if cflips == 0:
cheads += 1
return 'h'
else:
ctails += 1
return 't'
def repeat(f,n):
for i in range(n):
flip()
results = ""
while not results.endswith("hth"):
results += flip()
else:
flips = len(results)
print "it took" , flips , "to find HTH"
repeat(flip, 10000)
```

It's that flips variable towards the end. Every time the function executes, it changes. I want to run the flip() function 10,000 times and add up the flips variable 10,000 times as well. Usually, the number of flips is somewhere around 8-16, so my total should be somewhere around 80,000-160,000.

Thanks,
