How to replicate array to specific length array

I want replicate a small array to specific length array

Example:

var = [22,33,44,55] # ==> len(var) = 4
n = 13

The new array that I want would be:

var_new = [22,33,44,55,22,33,44,55,22,33,44,55,22]

This is my code:

import numpy as np
var = [22,33,44,55]
di = np.arange(13)
var_new = np.empty(13)
var_new[di] = var

I get error message:

DeprecationWarning: assignment will raise an error in the future, most likely because your index result shape does not match the value array shape. You can use arr.flat[index] = values to keep the old behaviour.

But I get my corresponding variable:

var_new
array([ 22.,  33.,  44.,  55.,  22.,  33.,  44.,  55.,  22.,  33.,  44.,
    55.,  22.])

So, how to solve the error? Is there an alternative?
