How can a list of integers be obtained from a list of arrays that contain objects?

edit

It depends on what type of objects the arrays contain and what integers are desired.

If the arrays contain integers themselves, then the list of arrays can be flattened to a single list using a nested loop or using the itertools library's chain method. Then, the integers can be extracted using list comprehension or a for loop that checks for the type of each element and appends the integer values.

If the arrays contain objects that have an integer attribute or method, such as a class with a "value" attribute, then the list of integers can be obtained by accessing that attribute or method in a nested loop or using list comprehension.

If the desired integers are not readily available in the objects within the arrays, then some manipulation or conversion of the objects may be necessary to generate the integers.
