Python | Pandas Series.nonzero () to get the index of all non-zero values ​​in a series

👻 Check our latest review to choose the best laptop for Machine Learning engineers and Deep learning tasks!

Pandas Series.nonzero() — it is a method with no arguments. As the name suggests, by returning non-zero values ‚Äã‚Äãfrom a series, it returns the index of all non-zero values. The returned series of indexes can be passed to the method iloc () to return all nonzero values ‚Äã‚Äãat those indices.

Exit:

 (array ([0, 2, 3, 5, 6 , 8, 9]),) 0 1 2 12 3 1 5 4 6 22 8 3 9 9 dtype: int64 

As shown in the output, the index position of each nonzero element was returned, and the values ‚Äã‚Äãin this positions were returned by the iloc method.
