R function rep() in Python (replicates elements of a list/vector)

Question

The R function rep() replicates each element of a vector:

> rep(c(\"A\",\"B\"), times=2)
[1] \"A\" \"B\" \"A\" \"B\"

This is like the list m

Answer 1

Use numpy arrays and the numpy.repeat function:

import numpy as np

x = np.array(["A", "B"])
print np.repeat(x, [2, 3], axis=0)

['A' 'A' 'B' 'B' 'B']
