How to get the first or last few rows from a Series in Pandas?

Example of Head():

import pandas as pd

values = ["India", "Canada", "Australia",
          "Japan", "Germany", "France"]

code = ["IND", "CAN", "AUS", "JAP", "GER", "FRA"]

ser1 = pd.Series(values, index=code)

print("-----Head()-----")
print(ser1.head())

print("\n\n-----Head(2)-----")
print(ser1.head(2))

C:\python\pandas examples>python example1e.py
-----Head()-----
IND        India
CAN       Canada
AUS    Australia
JAP        Japan
GER      Germany
dtype: object
 
 
-----Head(2)-----
IND     India
CAN    Canada
dtype: object
 
C:\python\pandas examples>

Example of Tail():

import pandas as pd

values = ["India", "Canada", "Australia",
          "Japan", "Germany", "France"]

code = ["IND", "CAN", "AUS", "JAP", "GER", "FRA"]

ser1 = pd.Series(values, index=code)

print("-----Head()-----")
print(ser1.head())

print("\n\n-----Head(2)-----")
print(ser1.head(2))

C:\python\pandas examples>python example1e.py
-----Tail()-----
CAN       Canada
AUS    Australia
JAP        Japan
GER      Germany
FRA       France
dtype: object
 
 
-----Tail(2)-----
GER    Germany
FRA     France
dtype: object
 
C:\python\pandas examples>

Example of Take():

import pandas as pd

values = ["India", "Canada", "Australia",
          "Japan", "Germany", "France"]

code = ["IND", "CAN", "AUS", "JAP", "GER", "FRA"]

ser1 = pd.Series(values, index=code)

print("-----Take()-----")
print(ser1.take([2, 4, 5]))

C:\python\pandas examples>python example1e.py
-----Take()-----
AUS    Australia
GER      Germany
FRA       France
dtype: object
