BUG: DynamicOneDimensionalArray's size is not updated properly

Example of the problem

def test_DynamicOneDimensionalArray3():
    DODA = DynamicOneDimensionalArray
    A = DODA(int, 1)
    A.delete(1)
    print(A._size)
    print(str(A))
    A.append(2)
    print(str(A))
    print(A.size)
    A.append(3)
    print(str(A))
    print(A.size)

Output:

1
[]
['2']
1
['2', '3']
3

The final size should be 2, but it is 3.

What's the output given by len(A)?

[Kishan-Ved]

It is the same as A.size for all the 3 cases in the code above.

[czgdp1807]

Actually size is correct. len(A) should give 2 in the end. Also check the references in the DODA docs.

[yuvraj-rathod-1202]

is this bug or not because when I set len to self._num it give correct len = 2 but when I run tests it was giving error that
"""
if size != len(data):
raise ValueError("Conflict in the size, %s and length of data, %s"
%(size, len(data)))
ValueError: Conflict in the size, 2 and length of data, 3
"""

here in this issue size should be 3 but length should be 2, but i still confuse can you let me know that what should i do
