I just looked up array and arrayList
and found out that an array is fixed length and can't be changed while an arraylist can be changed and is variable in length
my question is:
is array == tuple in python?
and is arraylist == list in python?
and if they aren't what are array and arraylist's python equivalent?

Lists and arrays are two of the most widely used data structures in Python. A list in Python is simply a collection of objects. These objects can be integers, floating point numbers, strings, boolean values or even other data structures like dictionaries.
Although people compare Python lists to arrays in Java, actually lists are more like ArrayLists in Java (Or Vectors in C++). Lists in Python store pointers to objects rather than objects themselves, which is why they can store heterogenous types ([1,2,3,'x',"hello"]).
To convert ArrayList to array in Java, we can use the toArray(T[] a) method of the ArrayList class. It will return an array containing all of the elements in this list in the proper order (from first to last element.)
ArrayList in java and list in python are both dynamic arrays. They both have O(1) average indexing time and O(1) average adding an element to the end time.
Array in java is not tuple in python. While it is true that you cannot add elements to both data structures. Python tuple does not support assignment, that is you cannot reassign individual elements in a tuple, while you can in java Array.
