How to append elements to a Pandas series?

In this program, we will append elements to a Pandas series. We will use the append() function for this task. Please note that we can only append a series or list/tuple of series to the existing series.

Algorithm

Step1: Define a Pandas series, s1.
Step 2: Define another series, s2.
Step 3: Append s2 to s1.
Step 4: Print the final appended series.

Example Code

import pandas as pd

s1 = pd.Series([10,20,30,40,50])
s2 = pd.Series([11,22,33,44,55])

print("S1:\n",s1)
print("\nS2:\n",s2)

appended_series = s1.append(s2)
print("\nFinal Series after appending:\n",appended_series)

Output

S1:
0    10
1    20
2    30
3    40
4    50
dtype: int64

S2:
0    11
1    22
2    33
3    44
4    55
dtype: int64

Final Series after appending:
0    10
1    20
2    30
3    40
4    50
0    11
1    22
2    33
3    44
4    55
dtype: int64
