30 Must-Know Tools for Python Development

Sponsored Content

Python development involves various stages and equally many tools to manage them:

• For dependencies, tools like pip, Conda, and Poetry help.
• For profiling, psutil and Scalene have been popular. But the newly launched Perforator is providing a much more reliable production-ready continuous profiling app to collect CPU profiles without affecting performance.

We gathered several such popular tools in the following visual:

The objective is to provide a structured overview of the essential tools developers can use across different aspects of Python development.

Let’s explore each category and its top tools in more detail.

1. Dependency & Package Managers

 
Manage Python package installations and dependencies.

• pip – The default package manager for Python, used to install and manage libraries.
• Conda – A package, dependency, and environment manager supporting multiple programming languages.
• Poetry – A dependency management tool that simplifies package management and publishing.

2. Monitoring and Profiling

 
Optimize and analyze performance.

• psutil – Provides system and process utilities for monitoring resource usage.
• Perforator – A cluster-wide continuous profiling tool designed for large data centers.
• Scalene – A high-performance Python profiler for CPU, memory, and GPU usage.

3. Virtual Environments

 
Ensure project isolation and manage dependencies efficiently.

• pyenv – Helps manage multiple Python versions on a system.
• virtualenv – Creates isolated Python environments to manage dependencies efficiently.
• pipenv – Combines pip and virtualenv for better dependency management.

4. Linters & Style Checkers

 
Enforce coding standards and maintain code quality.

• Pylint – Checks for errors and enforces coding standards.
• Ruff – A fast Python linter and formatter.
• Flake8 – Combines various linting tools into a single framework.

5. Type Checkers

 
Ensure type correctness in Python codebases.

• mypy – A static type checker for Python.
• Pyright – A fast type checker developed by Microsoft.
• Typeguard – A runtime type checker for Python.

6. Logging

 
Monitor application behavior and track issues.

• Rich – Provides beautiful console output with formatting, tables, and progress bars.
• Loguru – A modern logging framework for Python.
• tqdm – A simple, fast progress bar for loops.

7. Testing

 
Automate testing for software reliability.

• pytest – A widely used testing framework for Python.
• hypothesis – A property-based testing library.
• Robot Framework – A keyword-driven testing framework.

8. Debugging

 
Identify and fix issues in your code.

• PDB – The built-in Python debugger.
• Icecream – A debugging tool that prints variables and expressions.
• PySnooper – A lightweight debugging utility that logs function execution details.

9. Code Refactoring

 
Improve and restructure code efficiently.

• Jedi – An autocompletion and static analysis library for Python.
• Sourcery – An AI-powered code refactoring tool.
• Vulture – Finds unused code in Python projects.

10. Code Security

 
Detect and mitigate security vulnerabilities.

• Bandit – A security linter for identifying vulnerabilities in Python code.
• Safety – Checks Python dependencies for security vulnerabilities.
• Detect-Secrets – Scans code for hardcoded secrets.

These tools are invaluable for any Python developer, helping with everything from virtual environments and dependency management to debugging, logging, and security.

Incorporating them into your workflow can significantly improve your development experience and code quality.
