Pandas

Data structures refer to specia­lized way of storing data so as to apply a specific type of functi­onality on them.

Pandas has three data struct­ures.
1. Series
2. DataFrame
3. Panel

What are series?

Series is an important data structure of pandas.

1. A series is an one dimens­ional array containing a sequence of values of any data type (int, float, list, string etc.)
2. The data label associated with a particular value is called its index.
3. Default index always starts from zero, we can also assign our own user defined indexes which can be of any data type.

Creation of series

1.
import pandas as pd
s1=pd.Series([56,72,93,95])
print (s1)

OUTPUT
0           56
1           72 
2           93
3           95

2.
import pandas as pd
s1=pd.Series([56,72,93,95]), index=['a','b','c','d']
print(s1)
• always put "­import pandas as pd" before every command.
• when no index is specified, default index is applied.
• The "­S" in Series has to always be in capital
