`pandas` is the library in Python for data manipulating and processing. This library allows to work with sets of information in a convenient form. This library is a must-have skill for each data analyst.

To start working with library, you must import it. Like `NumPy`, `pandas` also has convention on alias: `pd`: `import pandas as pd`. To make sure you have successfully loaded the library, you may simply print it!

# Importing library
import pandas as pd
print(pd)

As you can see, the library has been loaded successfully.

This course is designed to teach you the very basics of pandas - a must-have  Python library for every data analyst or data scientist (and not only). You will start from defining the basic objects, learn how to read data from files, and how to manipulate and aggregate loaded data.

In the first section of the course you will learn two basic objects provided by pandas - Series and DataFrame. You will learn how to create them and change their indexes or column names.

Often the necessary data are stored in some files. You need to be able to load these data and gain the first insights.

Once you have loaded the data as Series/DataFrame, you need to be able to get certain data based on needs. You will learn how to access rows, columns, and filter observations by conditions.

In the last section of the course, you will get to know how to calculate some aggregate statistics of your data, such as mean, median, sum, product. Also you will learn how to count values and get only unique observations.
