True, it will produce a list. If you're worried about efficiency, you could use xrange(N) in Python 2.x. I'm not sure how it's bordering on the incorrect, however. I prefer it to a = range(N) because every element starts out at a sensible "default". I guess it's a matter of opinion. 2011-03-05T21:03:59.693Z+00:00 ... Save this answer. ...

July 18, 2026 - When an object is passed to an if statement, Python checks the truthiness of that object. And when it comes to collections, truthiness checks are non-emptiness checks. What if we checked for an empty list by comparing our list to another empty list:

November 22, 2019 - That means whatever is done behind the scenes has native support in C for determining if the list is empty. If you look into the source code of Python, you’ll find that the comparison is looking at the C object’s size property and returning True if it is greater than 0 or False if it isn’t.

If by "array" you actually mean a Python list, you can use
Use with AIa = [0] * 10
or
Use with AIa = [None] * 10
2 of 10

You can't do exactly what you want in Python (if I read you correctly). You need to put values in for each element of the list (or as you called it, array).
But, try this:
Use with AIa = [0 for x in range(N)] # N = size of list you want
a[i] = 5 # as long as i < N, you're okay
For lists of other types, use something besides 0. None is often a good choice as well.

September 27, 2023 - The proper way to define an empty list is not by using List this way, as List is not a built-in type in Python (it should be list()). Consequently, the right answer is option C: L=list(), as it creates an empty list in Python.
