Web20 jun. 2024 · Our target element is in the second row of the selected two-dimensional array. The row index is 1. We can select the row with this code: x[1][1]. Finally, the column index is 2 because from the picture above it shows that it is the third element. Combining: x[1][1][2] #output: 22. Return the first rows of the last two two-dimensional array WebIn the first example we looped over the entire DataFrame. iterrows () returns a Series for each row, so it iterates over a DataFrame as a pair of an index and the interested columns as Series. This makes it faster than the …
