What is the runtime complexity of python list functions?

Question

I was writing a python function that looked something like this

def foo(some_list):
   for i in range(0, len(some_list)):
       bar(some_list[i], i)
         


        

Answer 1

if you need index and value then use enumerate:

for idx, item in enumerate(range(10, 100, 10)):
    print idx, item
