Row Objects
Working with the ooodev.utils.data_type.row_obj.RowObj
class.
Comparison
Rules
can be compared to other
RowObj
can be compare to
int
Example
>>> from ooodev.utils.data_type.row_obj import RowObj
>>>
>>> r1 = RowObj.from_int(1)
>>> r2 = RowObj(2)
>>> r2 > r1
True
>>> r1 < r2
True
>>> r2 <= r2
True
>>> r2 >= r2
True
>>> r2 >= 2
True
>>> 2 <= r2
True
>>> r2 == 2
True
>>> 2 == r2
True
>>> r1 > r2
False
Previous and Next
>>> from ooodev.utils.data_type.row_obj import RowObj
>>>
>>> r6 = RowObj(6)
>>> r6
RowObj(value=6)
>>> r5 = r6.prev
>>> r5
RowObj(value=5)
>>> r5.prev
RowObj(value=4)
>>> r2 = r5.prev.prev.prev
>>> r2
RowObj(value=2)
>>> r8 = r6.next.next
>>> r8
RowObj(value=8)
Addition and Subtraction
Rules
can add and subtract to other
RowObj
can add and subtract
int
Attempt to make negative
RowObj
result inIndexError
Example
>>> from ooodev.utils.data_type.row_obj import RowObj
>>>
>>> r2 = RowObj(2)
>>> r5 = r2 + 3
>>> r5
RowObj(value=5)
>>> r3 = r5 - 2
>>> r3
RowObj(value=3)
>>> r8 = r5 + r3
>>> r8
RowObj(value=8)
>>> r6 = sum([r2, r2, r2])
>>> r6
RowObj(value=6)
>>> r2 - r5
IndexError
Multiply and Divide
Rules
can multiply and divide to other RowObj
can multiply and divide int
Attempt to make negative RowObj result in IndexError
Example
>>> from ooodev.utils.data_type.row_obj import RowObj
>>>
>>> r2 = RowObj(2)
>>> r20 = r2 * 10
>>> r20
RowObj(value=20)
>>> r40 = r2 * r20
>>> r40
RowObj(value=40)
>>> r20 = r40 / 2
>>> r20
RowObj(value=20)
>>> r10 = r20 / r2
>>> r10
RowObj(value=10)
>>> r2 / r10
IndexError
