** Parameters :**

** array: ** [array_like] Input array. ** repetitions: ** No. of repetitions of arr along each axis.

** Return: **

An array with repetitions of array - arr as per d, number of times we want to repeat arr

** Code 1: **

` # Python program illustrating ` ` # numpy.tile () ` ` import ` ` numpy as geek ` ` # Working on 1D ` ` arr ` ` = ` ` geek.arange (` ` 5 ` `) ` ` print ` ` (` ` "arr:" ` `, arr) ` ` repetitions ` ` = ` ` 2 ` ` print ` ` (` ` "Repeating arr 2 times:" ` `, geek.tile (arr , repetitions)) ` ` repetitions ` ` = ` ` 3 ` ` print ` ` (` `" Repeating arr 3 times: "` `, geek.tile (arr, repetitions)) ` ` # [0 1 2 ..., 2 3 4] means [0 1 2 3 4 0 1 2 3 4 0 1 2 3 4] ` ` # since this was long output, so it uses [...] ` |

** Output: **

arr: [0 1 2 3 4] Repeating arr 2 times: [0 1 2 3 4 0 1 2 3 4] Repeating arr 3 times: [0 1 2 ..., 2 3 4]

Code 2:

` # Python program illustrating ` ` # numpy .tile () ` ` import ` ` numpy as geek ` ` arr ` ` = ` ` geek.arange (` ` 3 ` `) ` ` print ` ` (` `" arr: "` `, arr) ` ` ` ` a ` ` = ` ` 2 ` ` b ` ` = ` ` 2 ` ` repetitio ns ` ` = ` ` (a, b) ` ` print ` ` (` ` "Repeating arr:" ` `, geek.tile (arr, repetitions)) ` ` print ` ` (` ` "arr Shape: "` `, geek.tile (arr, repetitions) .shape) ` ` ` ` a ` ` = ` ` 3 ` ` b ` ` = ` ` 2 ` ` repetitions ` ` = ` ` (a, b) ` ` print ` ` (` ` "Repeating arr:" ` `, geek.tile (arr, repetitions)) ` ` print ` ` (` ` "arr Shape:" ` `, geek.tile (arr, repetitions) .shape) ` ` a ` ` = ` ` 2 ` ` b ` ` = ` ` 3 ` ` repetitions ` ` = ` ` (a, b) ` ` print ` ` (` ` "Repeating arr:" ` `, geek.tile (arr, repetitions)) ` ` print ` ` (` ` "arr Shape:" ` `, geek.tile (arr , repetitions) .shape) ` |

** Output: **

arr: [0 1 2] Repeating arr: [[0 1 2 0 1 2] [0 1 2 0 1 2]] arr Shape: (2, 6) Repeating ar r: [[0 1 2 0 1 2] [0 1 2 0 1 2] [0 1 2 0 1 2]] arr Shape: (3, 6) Repeating arr: [[0 1 2 ..., 0 1 2] [0 1 2 ..., 0 1 2]] arr Shape: (2, 9)

** Code 3: (repetitions == arr.ndim) == 0 **

` # Python program illustrating ` ` # numpy.tile () ` ` import ` ` numpy as geek ` ` arr ` ` = ` ` geek.arange (` ` 4 ` `). reshape (` ` 2 ` `, ` ` 2 ` ` ) ` ` print ` ` (` ` "arr:" ` , arr) ` a ` ` = ` ` 2 ` ` b ` ` = ` ` 1 ` ` repetitions ` ` = ` ` (a, b) ` ` print ` ` (` ` "Repeating arr:" ` `, geek.tile (arr, repetitions)) ` ` print ` ` (` ` "arr Shape:" ` `, geek.tile (arr, repetitions) .shape) ` ` a ` ` = ` ` 3 ` ` b ` ` = ` ` 2 ` ` re petitions ` ` = ` ` (a, b) ` ` print ` ` (` ` "Repeating arr:" ` `, geek.tile (arr, repetitions)) ` ` print ` ` (` ` "arr Shape: "` `, geek.tile (arr, repetitions) .shape) ` ` ` ` a ` ` = ` ` 2 ` ` b ` ` = ` ` 3 ` ` repetitions ` ` = ` ` (a, b) ` ` print ` ` (` ` "Repeating arr:" ` `, geek.tile (arr, repetitions)) ` ` print ` < code class = "plain"> ( ` "arr Shape:" ` `, geek.tile (arr, repetitions) .shape) ` |

** Output: **
