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

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()

Browser

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.

Node

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()

Browser

Output

╔═══╤═════╗
║ 0 │ 12  ║
╟───┼─────╢
║ 1 │ 34  ║
╟───┼─────╢
║ 2 │ 2.2 ║
╟───┼─────╢
║ 3 │ 2   ║
╟───┼─────╢
║ 4 │ 30  ║
╚═══╧═════╝

By specifying a start index in a slice, all values after that index are returned.

Node

const dfd = require("danfojs-node")

let s = new dfd.Series([12, 34, 2.2, 2, 30, 30, 2.1, 7])
s.iloc(["5:"]).print()

Browser

Output

╔═══╤═════╗
║ 5 │ 30  ║
╟───┼─────╢
║ 6 │ 2.1 ║
╟───┼─────╢
║ 7 │ 7   ║
╚═══╧═════╝

Slice Series by boolean condition

Node

const dfd = require("danfojs-node")

let s = new dfd.Series([12, 34, 2.2, 2, 30, 30, 2.1, 7])
s.iloc(s.gt(20)).print()

╔═══╤════╗
║ 1 │ 34 ║
╟───┼────╢
║ 4 │ 30 ║
╟───┼────╢
║ 5 │ 30 ║
