How do I get an empty array of any size in python?

Question

I basically want a python equivalent of this in C:

int a[x];

but in python I declare an array like:

a = []

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:

a = [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.
