Answer 1

Python is dynamically typed. You do not need (and actually CANNOT) create a list containing only one type:

 arr = list() arr = [] 

If you only need to contain one type, you will have to create your own list by renaming the list methods and __setitem__() yourself.

Answer 2

You can create arrays of only one type using array , but it is not intended to store custom classes.

The python way is to simply create a list of objects:

 a = [myCls() for _ in xrange(10)]

Note:

Be careful with these notations, IT IS NECESSARY WHAT YOU INTEND TO:

 a = [myCls()] * 10 

This will also create a list with a tenfold increase in the myCls object, but it will be ten times larger than one separate object, and not ten independently created objects.
