Jun 17, 2014 · The central feature of NumPy is the array object class. Arrays are similar to lists in Python, except that every element of an array must be of the same type, typically a numeric type like float or int. Arrays make operations with large amounts of numeric data very fast and are generally much more efficient than lists.

, array of string. However, in Python, there is no native array data structure. So, we use Python lists instead of an array. Note: If you want to create real arrays in Python, you need to use NumPy's array data structure. For mathematical problems, NumPy Array is more efficient.
