Introducing pandas Series, pandas DataFrames, and pandas Indexes

pandas Series, pandas DataFrames, and pandas Indexes are the fundamental pandas data structures.

pandas.Series

The pandas.Series data structure represents a one-dimensional series of homogenous values (integer values, string values, double values, and so on). Series are a type of list and can contain only a single list with an index. A Data Frame, on the other hand, is a collection of one or more series.

Let's create a pandas.Series data structure:

import pandas as pd
ser1 = pd.Series(range(1, 6)); 
ser1

That series contains the index in the first column, and in the second column, the index's corresponding values:

0    1
1    2
2    3
3    4
4    5
dtype: int64

We can specify custom index names by specifying the index parameter:

ser2 = pd.Series(range(1, 6),
