What Python libraries have you used in your projects?

In Python projects, I often used the following libraries:

• requests — for working with HTTP requests.
• pandas — for data processing and analysis.
• numpy — for numerical computations and working with arrays.
• flask — for creating web applications.
• sqlalchemy — for working with databases through ORM.
• pytest — for writing and running tests.

For example, pandas makes it easy to read CSV files and process tables:

import pandas as pd

df = pd.read_csv('data.csv')
print(df.head())
