The Pandas library is a powerful open-source tool specifically designed for data analysis in Python. It offers high-performance, easy-to-use data structures and data manipulation functions.
Pandas provides a number of useful data structures to perform various operaitons with the data effectively.
a. Series: A one-dimensional array of data
b. DataFrame: A two-dimensional array of data
c. Panel: A three-dimensional array of data
d. TimeSeries: A Series that represents time-ordered data
e. DataReader: Helps to read data from a variety of sources, such as CSV files, databases etc.,
