Python is a widely-used programming language used in virtually every industry. It’s user friendly, straightforward to learn, and powerful enough to enable developers to craft reliable software for almost any purpose.
Python can be installed on a variety of operating systems, including Windows. In this article, we’ll guide you through installing Python on Windows.
Download
Python is a free and open-source programming language available for Windows PC download from the Python website.
Python offers several methods for downloading its executable installer and web-based installer. The latter significantly reduces the download size, but you must have access to a network connection to use it.
You may install a self-contained zip file containing only the Python runtime and no other dependencies. This option is ideal for experienced users who require an efficient one-off installation without access to a network connection.
Once you’ve downloaded Python, go to the web-based installer and select an install directory. Here, you can decide whether this application should be installed for all users or just you and which features you would like. Finally, click Install to complete the installation.
Installation
Python is a widely-used high-level programming language designed for general-purpose programming. Although not natively supported on Windows, it can easily be installed on most systems.
Installing Python on a Windows system requires downloading an installer from the official Python website and running it. This will install the Python interpreter – which converts your Python scripts into bytecodes and executes them – into your system.
Step 1: Navigate to the Python website and choose which version of Python you need for your computer. Depending on your system specs, you can download either a Windows x86 or 64-bit executable installer.
You can customize the installation of Python on Windows by altering the %PATH% variable, where Python searches for files. You may also disable the path length limit, which prevents Python from using paths longer than 260 characters – this option does not break anything. It helps resolve any potential path-related issues you may encounter while working with Python on your machine.
Compatibility
Python is one of the most widely-used programming languages for web development and software applications. It also has artificial intelligence, machine learning, and data science applications.
Python runs on both 32-bit and 64-bit versions of Windows, but it’s essential to select the right one for your project. For instance, many data analysis tools require 64-bit versions of Python as they can access more significant amounts of memory than their 32-bit equivalents.
However, Windows still uses legacy encodings (the ANSI Code Page) when reading and writing files. Therefore, it’s recommended to use Python UTF-8 Mode instead of the system encoding for text files; this can be enabled via either the -X utf8 command line option or the PYTHONUTF8=1 environment variable.
The Python launcher for Windows can be used to locate and launch different Python versions on Windows. It supports version qualifiers, enabling scripts to specify their preference for a particular version of Python, with which the launcher will then locate and execute that specific code.
Security
When installing Python, it is essential to take some basic security precautions. These measures will prevent malware from invading your system and secure the python environment.
Utilizing an absolute path instead of an implicit one is one of the best methods to prevent dependency confusion and Trojan horse installations from malicious Python packages. Using a fundamental way, you can quickly identify and verify which package contains valid code before installing it on your system.
Another security measure that should be implemented when installing Python is using virtual environments. This will allow different projects to be kept separate and isolated.
It is essential always to sanitize external data upon entry into your application. Doing so can reduce the risk of insecure handling and exploits such as injection, XSS, or DOS attacks.
