Series.iloc

danfo.Series.iloc()
Parameters
Type
Description
Default
rows
Array or String slice
Array, string slice, index of row positions boolean mask to filter by.
​
Examples
.iloc() is primarily integer position based (from 0 to length-1 of the axis).
Allowed inputs are:
An integer, e.g. 5.
A list or array of integers, e.g. [4, 3, 0].
A boolean mask. E.g [ true, false, false ]
A string slice object with ints, e.g. "1:7"
Note: only **** the start label is included, and the end label is ignored.
.iloc will raiseIndexError if a requested indexer is out-of-bounds.
Indexing specific rows by index
Node
Browser
const dfd = require("danfojs-node")
​
let s = new dfd.Series([12, 34, 2.2, 2, 30, 30, 2.1, 7])
s.iloc([0,5]).print()
​
Output
╔═══╤════╗
║ 0 │ 12 ║
╟───┼────╢
║ 5 │ 30 ║
╚═══╧════╝
Index by a slice of row
The iloc function also accepts string slices of the form [start: end], e.g "[0: 5]". This will return all values from index positions 0 to 4.

​
Output
╔═══╤═════╗
║ 0 │ 12  ║

║ 3 │ 2   ║

║ 4 │ 30  ║
╚═══╧═════╝
By specifying a start index in a slice, all values after that index are returned.
