6. Types of
Libraries used
for Data
Analytics

7. Pandas Matplotlib

8. What are
Virtual
Enviroments.
are self-contained, isolated spaces where
you can install specific versions of software
packages, including dependencies, libraries,
and Python versions.
This isolation helps avoid conflicts between
package versions and ensures that your
projects have the exact libraries and tools
they need.
***we will be using Anaconda.

9. Introduction to
Pandas
What is Pandas?
•Pandas is a Python library for data manipulation and analysis.
•It provides easy-to-use structures like Series (1D) and DataFrame (2D).
•It’s widely used in data science, machine learning, and financial analysis.
Why Pandas?
•Handles large datasets efficiently.
•Provides built-in functions for cleaning and transforming data.
•Works well with other libraries like NumPy and Matplotlib.
The data produced by Pandas is often used as input for plotting functions in Matplotlib, statistical analysis in SciPy, and
machine learning algorithms in Scikit-learn.

11. Introduction to
Matplotlib
“Matplotlib is a comprehensive library for creating static, animated, and interactive
visualizations in Python. Matplotlib makes easy things easy and hard things possible.”
Matplotlib Pyplot
Pyplot is a module within Matplotlib that provides a MATLAB-like interface for making plots.
It simplifies the process of adding plot elements such as lines, images, and text to the axes
of the current figure.
