Important Points to Remember about Pandas Series

NumPy, Pandas and Matplotlib are Python libraries for scientific and analytical use. 

pip install pandas is the command to install Pandas library.

A data structure is a collection of data values and the operations that can be applied to that data. It enables efficient storage, retrieval and  modification to the data. 

Two main data structures in Pandas library are Series and DataFrame. To use these data structures, we first need to import the Pandas library.

A Series is a one-dimensional array containing a sequence of values. Each value has a data label associated with it also called its index. 

The two common ways of accessing the elements of a series are Indexing and Slicing.

There are two types of indexes: positional index and labelled index. Positional index takes an integer value that corresponds to its position in the series starting from 0, whereas labelled index takes any user-defined label as index 

When positional indices are used for slicing, the value at end index position is excluded, i.e., only (end - start) number of data values of the series are extracted. However with labelled indexes the value at the end index label is also included in the output. 

All basic mathematical operations can be performed on Series either by using the operator or by using appropriate methods of the Series object. 

While performing mathematical operations index matching is implemented and if no matching indexes are found during alignment, Pandas returns NaN so that the operation does not fail.

Pandas Series	NumPy Arrays
In series we can define our own labeled index to access elements of an array.	In NumPy Arrays we can not define our own labeled index to access elements of an array
Series require more memory	NumPy occupies lesser memory.
The elements can be indexed in descending order also.	The indexing starts with zero for the first element and the index is fixed
