Hello,
I profiled my python program and found that the following function was taking too long to run. Perhaps, I can use a different algorithm and make it run faster. However, I have read that I can also possibly increase the speed by reducing function calls, especially when it gets called repeatedly within a loop. I am a python newbie and would like to learn how to do this and see how much faster it can get. Currently, the function is:
def potentialActualBuyers(setOfPeople,theCar,price):
count=0
for person in setOfPeople:
if person.getUtility(theCar) >= price and person.periodCarPurchased==None:
count += 1
return count
where setOfPeople is a list of person objects. I tried the following:
def potentialActualBuyers(setOfPeople,theCar,price):
count=0
Utility=person.getUtility
for person in setOfPeople:
if Utility(theCar) >= price and person.periodCarPurchased==None:
count += 1
return count
This, however, gives me an error saying local variable 'person' referenced before assignment
Any suggestions, how I can reduce function calls or any other changes that can make the code faster.
Again, I am a python newbie and even though I may possibly be able to use a better algorithm, it is still worthwhile learning the answer to the above question.
Thanks very much.
