Race-condition creating folder in Python

Question

I have a urllib2 caching module, which sporadically crashes because of the following code:

if not os.path.exists(self.cache_location):
    os.mkdir(self.cach         


        

Answer 1

When you have race conditions often EAFP(easier to ask forgiveness than permission) works better that LBYL(look before you leap)
