equals(other, rtol=None, atol=None, traceback=False)

True if two instances are logically equal, False otherwise.

Parameters :

other :

The object to compare for equality.

atol : float, optional

The absolute tolerance for all numerical comparisons, By default the value returned by the ATOL function is used.

1
>>> s.index(2, start=2)
3
>>> s.index(2, start=2, stop=4)
3
