Various knowledge and considerations to have before installing Python
- Identify Your Purpose: Determine why you need Python. Whether it’s for web development, data analysis, machine learning, automation, or any other purpose, understanding your intended use will help you choose the right Python version and additional tools and libraries.
- Choose the Python version: Decide which version of Python to install. Python 2.x is nearing its end of life, so it’s generally recommended to opt for Python 3.x, the current version that is actively maintained and regularly updated.
- Check Operating System Compatibility: Ensure that the Python version you choose is compatible with your operating system (Windows, macOS, or Linux). Python is cross-platform, but you’ll need to download the appropriate installer for your OS.
- Select Installation Method: Choose how you want to install Python based on your preferences and needs. Options include using the official installer from the Python website, package managers like Homebrew (for macOS and Linux), or distribution-specific package managers for Linux distributions.
- Consider Environment Management: Think about whether you need to set up virtual environments. Virtual environments allow you to create isolated Python environments for different projects, preventing dependency conflicts. Tools like virtualenv or Python 3’s built-in venv module can help manage virtual environments.
- Identify additional tools and libraries: Determine if you’ll need any additional tools or libraries for your Python projects, such as NumPy, Pandas, TensorFlow, Django, or Flask. These can be installed using Python’s package manager, pip, after Python itself is installed.
- Configure Path Settings: During installation, you may have the option to add Python to your system’s PATH environment variable. This enables you to run Python and Python scripts from any directory in the command prompt or terminal, enhancing ease of use.
- Check System Requirements: Make sure your system meets the requirements for the Python version you plan to install, including processor architecture, memory, and disk space. This ensures a hassle-free installation and optimal performance.

System Requirements for Python
System requirements for Python for Windows:
- Operating System Compatibility: Python supports various Windows versions, including Windows 7, 8, 8.1, and 10. Ensure your system runs a compatible Windows version.
- Processor Requirements: Python is lightweight and can run on most modern processors compatible with Windows.
- Memory (RAM): Python’s memory requirements are modest. A system with 2GB of RAM is usually sufficient for basic usage. However, more RAM may be beneficial for tasks involving large datasets or memory-intensive operations.
- Disk Space: The disk space needed for installing Python itself is minimal, typically less than 1GB. However, if you plan to install additional packages using pip, allocate extra disk space accordingly.
- Python Version: Opt for Python 3.x, the recommended version, as Python 2.x has reached its end of life and no longer receives updates.
- Python Installer: Download the official Python installer for Windows from the Python website. Choose the correct installer for your system architecture (32-bit or 64-bit) and Python version.
- Administrator Privileges: Depending on your system settings, administrator privileges may be necessary for Python installation. Ensure you have the required permissions to install software on your system.
System requirements for Python for MacOS:
- Operating System Compatibility: Python is compatible with macOS versions supported by Apple. Ensure your macOS version is among those supported. Typically, Python works well on macOS versions starting with macOS 10.9 (Mavericks) and newer releases.
- Processor Requirements: Python is not demanding on the processor and can run smoothly on most modern CPUs found in Mac computers, including Intel-based and Apple Silicon (M1) processors.
- Memory (RAM): Python’s memory requirements are minimal. For basic usage, a system with 2GB of RAM is sufficient. However, if you plan to work with large datasets or engage in memory-intensive tasks, having more RAM may be advantageous.
- Disk Space: The disk space needed for Python installation itself is small, usually less than 1GB. However, if you intend to install additional packages or libraries using pip, allocate extra disk space accordingly. Reserve at least a few gigabytes of free disk space for Python and its associated libraries.
- Python Version: Opt for Python 3.x, the recommended version for macOS. Python 2.x has reached its end of life and is no longer supported.
- Python Installer: Obtain the official Python installer for macOS from the Python website. Ensure you select the appropriate installer compatible with your macOS version and the desired Python version.
- Administrator Privileges: Depending on your system settings, you may need administrator privileges to install Python on macOS. Verify that you possess the necessary permissions to install software on your Mac.
