As we know that NumPy, Pandas, Matplotlib, and Seaborn are essential libraries for Data Science and Machine Learning. So, Here is a small Introduction to these Data Libraries.

# 1. NumPy

NumPy stands for Numerical Python. It is a Python Package for mathematical and logical operations on arrays in Python. It is used in most Python Projects Involving managing data sets. It is different from Lists.

• NumPy can contain only one type of data, hence not flexible with data types.
• It is widely used for Arithmetic operations.
• It Cannot be directly Initialize. It can be operated with the NumPy package only.
• In NumPy functions like concatenation, appending, etc, are not trivially possible with arrays.
• Arrays take less memory space.

# 2. Pandas

Pandas is a library in Python for Data Manipulation and analysis. It offers data structures and operations for manipulating tables and time-series data. Pandas is built on top of NumPy and can be integrated with third parties libraries.

Pandas is well suited for many different kinds of data:

• Tabular data such as SQL table or Excel
• Time series data
• Any form of data sets - labeled or unlabelled

The two data structures of Pandas are:

• Series (1-D)
• DataFrame (2-D)

Few use cases of Pandas include:

• Handling of missing data or NaN
• Columns can be inserted and deleted from the data frame
• Slicing, indexing, and subsetting of large data sets
• Managing data sets - joining and pivoting

# 3. Matplotlib

Matplotlib is a visualization library built on NumPy in Python for 2-D plots of arrays. It is useful to visualize and interpret large data sets. Matplotlib comes with a variety of inbuilt plots and offers lots of flexibility.

# 4. Seaborn

Seaborn is a Python data visualization library based on Matplotlib. It provides a high-level interface for drawing attractive and informative statistical graphics.
