roll two fair die in python using int and not a string. here is the code i have and the feedback from my teacher -

from random import randrange  def roll():     return randrange(1,7)  def rolldice(n):     onecount = 0     twocount = 0     threecount = 0     fourcount = 0     fivecount = 0     sixcount = 0     in range (n):         dice = roll()         if dice == 1:             onecount = onecount +1         if dice == 2:             twocount = twocount +1         if dice == 3:             threecount = threecount +1         if dice == 4:             fourcount = fourcount +1         if dice == 5:             fivecount = fivecount +1         if dice == 6:             sixcount = sixcount +1      return (dice, onecount, twocount, threecount, fourcount, fivecount, sixcount)  def rolltwodice():     total = 0     turn in range(2):         total += roll()     return total  def rolltwodicecount(n):     twos = 0     turn in range(n):         if roll() == 2:             twos +=1 

message teacher:

>>> rolldice(6000)     (4, 996, 1022, 976, 991, 1018, 997 

that looks works, once figured out first 1 for.

>>> rolltwodice() 10 >>> rolltwodice() 4 >>> rolltwodice() 6 >>> rolltwodice() 7 >>>  >>> rolltwodice() 8 >>> rolltwodice() 8 >>> rolltwodice() 3 >>> rolltwodice() 8 >>> rolltwodice() 6 >>> rolltwodice() 6 >>> rolltwodice() 8 >>> rolltwodice() 6 >>> rolltwodice() 9 >>> rolltwodice() 6 >>> rolltwodice() 6 >>> rolltwodice() 9 >>> rolltwodice() 7 >>> rolltwodice() 9 >>> rolltwodice() 6 >>> rolltwodice() 5 >>> rolltwodice() 7 

hmm. no 2, 11, or 12. not problem, though.

>>> rolltwodicecount(36000) traceback (most recent call last):   file "<pyshell#28>", line 1, in <module>     rolltwodicecount(36000)   file "c:/users/jneitzke/downloads/alec25.py", line 41, in rolltwodicecount     sevens +=1 unboundlocalerror: local variable 'sevens' referenced before assignment 

okay, drove on cliff.

def rolltwodicecount(n):     twos = 0     turn in range(n):         if roll() == 2:             twos +=1             sevens +=1     print ("in", n, "rolls of 2 dice, there were",twos,"twos and",\            sevens,"sevens") 

yup. no initialization of seven.

it's kind of overkill, can complete profile did rolldice, first one. since have gone direction, that. doesn't scale well, it's okay 2 dice. more, forget it.

the more traditional way using dictionary, word count. scales.

count = {} newvalue = ????? if newvalue in count:   count[newvalue] += 1 else:   count[newvalue] = 1 

you need declare variable sevens before can read it. operator += reads current value of variable on left , appends value finds on right.

def rolltwodicecount(n):     twos = 0     sevens = 0     turn in range(n):         if roll() == 2:             twos +=1             sevens +=1     print ("in", n, "rolls of 2 dice, there were",twos,"twos and",\        sevens,"sevens")
