hidden python library

Python is known for its simplicity and versatility, but its real power comes from the vast ecosystem of libraries that developers can utilize. While some libraries like NumPy, Pandas, and TensorFlow are household names among Python enthusiasts, there are many hidden yet incredibly powerful libraries that can simplify complex tasks and boost productivity.

In this article, we’ll explore five Python libraries that you’ve probably never heard of but should definitely be using for advanced projects.


1. Pydantic

pydantic - hidden python libraries

Pydantic is an underrated Python library that focuses on data validation and settings management using Python type annotations. It provides a way to ensure that the data you are working with is valid and consistent.

  • Why Use It?
    Pydantic allows you to define data schemas with Python’s built-in typing annotations, and it will validate and parse the data at runtime. This is extremely useful in API development, where you often need to validate incoming data before processing it.
  • Key Features:
    • Supports complex data structures
    • Clear error messages for data validation
    • Easy to use with FastAPI for API building

Code Example:

from pydantic import BaseModel

class User(BaseModel):
id: int
name: str
is_active: bool = True

# Validating the input data
user = User(id=1, name='John Doe')
print(user)
  • Use Case: Pydantic is a go-to choice when building APIs or any data-driven applications where data validation is critical.

2. Rich

Rich is a Python library designed to make it easy to print beautiful and highly customizable terminal output. It helps developers add color and style to their command-line applications.

  • Why Use It?
    Rich provides the tools to format Python console output with colors, tables, progress bars, and even markdown.
  • Key Features:
    • Text formatting with styles and colors
    • Support for tables, markdown, and JSON rendering
    • Progress bars for tracking tasks in CLI

Code Example:

from rich import print

print("[bold green]Hello, World![/bold green]")
  • Use Case: Ideal for developers building command-line interfaces (CLI) that require rich visual output.

3. Typer

typer hidden python library

Typer is a library that simplifies the process of creating command-line interfaces. It’s built on top of Python’s Click library but provides even more flexibility by using Python 3.6+ type hints.

  • Why Use It?
    With Typer, you can build CLIs that are intuitive and simple to write. It automatically generates help documentation based on your function signatures.
  • Key Features:
    • Automatically generates CLI help documentation
    • Supports data validation through Pydantic
    • Requires minimal boilerplate code

Code Example:

import typer

def greet(name: str):
typer.echo(f"Hello {name}")

if __name__ == "__main__":
typer.run(greet)
  • Use Case: Typer is perfect for Python developers who frequently work on CLI applications and need a fast and easy way to generate them.

4. Poetry

poety hidden python library

Poetry is a Python dependency management tool that handles the packaging and publishing of Python libraries. It replaces traditional tools like setup.py and requirements.txt, making it easier to manage dependencies, virtual environments, and project configurations.

  • Why Use It?
    Poetry simplifies the entire lifecycle of Python projects by automating the packaging, dependency management, and environment setup.
  • Key Features:
    • Dependency resolution and version management
    • Simple project setup with pyproject.toml
    • Supports publishing packages to PyPI

Code Example:

poetry new my-package
cd my-package
poetry add requests
  • Use Case: Perfect for developers maintaining large Python projects or libraries that need to be published to PyPI.

5. Arrow

arrow hidden python library

Arrow is a library for creating, manipulating, and formatting dates and times in Python. It simplifies working with time zones, converting between different date formats, and handling time arithmetic.

  • Why Use It?
    Arrow provides a simple API for dealing with dates and times, removing much of the complexity found in Python’s built-in datetime module.
  • Key Features:
    • Easy manipulation of dates and times
    • Time zone-aware date and time objects
    • Human-friendly time formatting (e.g., “2 days ago”)

Code Example:

import arrow

# Get current time
now = arrow.now()

# Convert to a different time zone
utc = now.to('UTC')
  • Use Case: Arrow is ideal for applications that require extensive time calculations or need to work across different time zones.

Conclusion

These five Python libraries might not be as popular as Pandas or TensorFlow, but they offer powerful functionalities that can significantly improve your productivity and simplify complex tasks. Whether you’re building APIs, working on command-line interfaces, or managing Python projects, incorporating these libraries into your workflow can be a game-changer.
