Increasing speed of python code

Question

I have some python code that has many classes. I used cProfile to find that the total time to run the program is 68 seconds. I found that the following function in

Answer 1

Some curious things I noted:

timePd is passed as a parameter but never used

price is an array but you only ever use the last entry - why not pass the value there instead of passing the list?

count is initialized and never used

self.people contains multiple person objects which are then copied to either self.customers or self.noncustomers as well as having their customer flag set. Why not skip the copy operation and, on return, just iterate over the list, looking at the customer flag? This would save the expensive append.

Alternatively, try using psyco which can speed up pure Python, sometimes considerably.
