How to create a fix size list in python?

Question

In C++, I can create a array like...

int* a = new int[10];

in python,I just know that I can declare a list,than append some items,or like..

Answer 1

Note also that when you used arrays in C++ you might have had somewhat different needs, which are solved in different ways in Python:

1. You might have needed just a collection of items; Python lists deal with this usecase just perfectly.
2. You might have needed a proper array of homogenous items. Python lists are not a good way to store arrays.

Python solves the need in arrays by NumPy, which, among other neat things, has a way to create an array of known size:

from numpy import *

l = zeros(10)
