Hi,
I want to repeatedly search a list to test whether that list contains a given

Of course, I can use membership testing using "in" (list._contains__).
But how is this method implemented? It seems to just walk through the whole

beginning to end (see timeit code below). Is

shelve uses a database (e.g. gdbm) based on hashing. It's an unordered
mapping. Unlike a dict, the keys must be strings.

Oscar,
Thanks for that. I feel a bit silly. I forgot about the % which was
hanging me up. I am trying to be a better coder. More work ahead for me!

I forgot the obligatory warning about class variables. The subclass
gets a shallow copy of the parent class namespace. The in-place

Hi,
I am trying to understand the output of cProfile when run against my python
code. The code is:
from math import floor,sqrt
count = int(floor(sqrt(10)))
max_check = range(2,count+1)
original_list = range(2,11)
for j in max_check:
temp_list=[]
for i in original_list:

Python is not Java. In Python, classes are first-class objects (no pun
intended) and can be assigned to variables the same

Thanks for the input everyone.
@Dave, I basically implemented the sieve of eratosthenes to fiind the
number of prime numbers in a given range. So, yes I am looking for
suggestions to speed it up.
