Today I was playing around with Python 3.0 to see how many of the libraries can be converted, refactored or removed while utilizing the new features of python. First one that can potentially go is the permutations function since itertools now has one.
So here is my ( brute force ) solution to 43 using the permutations from itertools . Takes around 15 seconds to execute
import time
from itertools import permutations
def checkForProperty(t):
if (int(t[1:4])%2) != 0:
return False
if(int(t[2:5])%3) != 0:
return False
if (int(t[3:6])%5) != 0:
return False
if(int(t[4:7])%7) != 0:
return False
if(int(t[5:8])%11) != 0:
return False
if(int(t[6:9])%13) != 0:
return False
if(int(t[7:10])%17) != 0:
return False
return True
r = time.time()
print (sum([int(''.join(x)) for x in permutations('1234567890') if x[0] != '0' and checkForProperty(''.join(x))]))
print (time.time() - r)
