What are Libraries in Python?

Libraries in Python are collections of pre-written code that you can use to perform common tasks without writing code from scratch.

Popular Python Libraries

1. NumPy

Used for numerical operations.

Example:

import numpy as np arr = np.array([1,2,3])

2. Pandas

Used for data analysis.

Example:

import pandas as pd data = pd.DataFrame()

3. Matplotlib

Used for data visualization.

Example:

import matplotlib.pyplot as plt

Installing Libraries

You can install libraries using pip.

Example:

pip install numpy
