Repeat the elements in a pandas Series

Overview:

The repeat() method of pandas series returns a new series, with its elements repeating as per the specified frequency.
The repeat frequency can be specified for all the elements or at per element basis.
While a frequency of 0 will result in absence of a series or absence of an element, a frequency of 1 will not repeat the element, a frequency of 2 will repeat the element once, a frequency of 3 will repeat the element twice and so on.

# Example Python program to obtain a pandas Series

# of repeating entries from an existing pandas Series

import pandas as pds

evenNumbers = (2, 4, 6, 8);

series = pds.Series(evenNumbers);

print("Original series:");

print(series);

# Create a new series where each element is repeated twice

newSeries1 = series.repeat(2);

print("New Series1:");

print(newSeries1);

# Create a new series with the repeating frequency for each element

# is specified

newSeries2 = series.repeat((0, 1, 2, 3));

print("New Series2:");

print(newSeries2);

Original series:

0 2

1 4

2 6

3 8

New Series1:

0 2

1 4

2 6

3 8

dtype: int64

New Series2:

1 4

2 6
