Python implementation of stone scissors code sharing

I wrote an article before about JS based rock scissors program, and today I wrote an example based on Python, where the algorithm is a little special but I can't think of a good algorithm rule at the moment.

Code:

# encoding=UTF-8

#  Stone scissors   The program 

#  sasihorfswe 

import random

 

#  Define the stone scissors dictionary 

dict = {1:' scissors ',2:' stone ',3:' cloth '}

 

for row in dict:

    print ' Serial number :',row,' = ',dict[row]

 

print ' What's the matter with you? '

 

loop = True

while loop:

    you = raw_input(' Please enter the number enter : ')

    try:

        you = int(you)

        if you>=1 and you<=3:

            loop = False

        else:

            print ' Please enter the  1-3  Range number '

    except Exception,e:

        print ' Please enter the correct number '

 

dn = random.randint(1,3)

print ' You: ',dict[you]

print ' Computer: ',dict[dn]

print ' Results: ',

 

if dn==you:

    print ' A draw '

elif (you>dn and you-dn==1) or you+2==dn:

    print ' You win '

else:

    print ' The computer games '
