Is an array a collection in python?

There is no concept of array in Python. Array is a data structure. A collection is a data structure that contains a set of elements.

Summary of data structures in Python:

In Python there are only tuples and lists;

Once a tuple is created, it cannot be changed, for example: aa=tuple(1,2,3);

Tuples cannot append (append) elements or pop (pop) Elements, etc.;

Only the elements in the tuple can be indexed aa[0], and the tuples therein cannot be assigned aa[0]=8;

The advantage of using tuples is that operating on tuples is more efficient and suitable for storing a set of constants;

While many of the above are not possible, it is possible to use a list.

For arrays:

list: array

tuple: read-only array

dict: dictionary

set: Set (can be regarded as a set in a mathematical sense)
