Mastering Python Version Manager: Effortlessly Managing Python Versions
Managing Multiple Python Versions With pyenv
Why Use pyenv
?
pyenv
is a tool for managing multiple Python versions- It allows easy testing of different Python versions for projects or new language features
pyenv
enables the installation of pre-release versions of Python for testing
Why Not Use System Python?
- System Python is the Python version that comes installed with the operating system
- It is not ideal for testing different Python versions or managing project-specific requirements
- System Python is shared among all users and may not be the desired version
