Series Padding

Problem

Right-pad a series with pad_value until it reaches target_length. If the series is already at least that long, return it unchanged.

Return the padded list.

Hint

Padding aligns variable-length series for batched training.

case 1

in: [[1,2,3],5,0]

expected: [1,2,3,0,0]

case 2

in: [[1,2],2,9]

expected: [1,2]

case 3

in: [[1,2],4,-1]

expected: [1,2,-1,-1]

case 4

in: [[],3,0.5]

expected: [0.5,0.5,0.5]
