4. Run the Python installer Windows Installer
1. Choose custom installation
The Windows operating system allows the creation of multiple user accounts, each with its own permissions. Install Now defaults to installing for the current account, with default installation path and content.
Image 4-1 Default Python Installation
Use admin privileges when installing py.exe
In the Windows system, the Administrator account has the highest access rights and can access other accounts, while personal accounts do not have access rights to each other.
This option is checked to install the Python executable with administrator privileges.Installing Python with administrator privileges allows other Windows
accounts (User) to log into the system and use Python.
If this option is not checked, and the current account is a personal account, after installing Python, other non-administrator accounts logging into the Windows system cannot use the Python installed by this account.
Add python.exe to PATH
This option is checked to add Python to the Windows system path, making it easier for the operating system to recognize it automatically.
Image 4-1 Install Now defaults to automatically install IDLE, pip, documentation, Creates shortcuts
and file associations (creates shortcuts in the start menu, creates file associations).The default installation installs relatively basic content, but has the basic Python development functions. If you want to reduce or add functions or specify the installation path, you can choose custom installation.
Usually, we choose custom installation to add more features. The red box in Image 4-2 is for Customize installation,
below we choose custom installation.
Image 4-2 Python Custom Installation
Check Use admin privileges when installing py.exe and Add python.exe to PATH, click
=Customize installation to enter the custom installation, entering the Python optional features settings interface as shown in Image 4-3.
2. Optional Features Settings
Documentation
Install the offline documentation files for Python, which are generally the usage instructions for Python. This option is optional.
pip
Install pip, which can install external libraries for Python in the cmd command window. This option is checked.After installation, you can press win+r to start the run window, input cmd in the cmd command window, and type pip install
tcl/tk and IDLE
Install tkinter and IDLE development environment, whether this option is checked can be determined by demand.The Tkinter module is the interface for Python’s standard Tk GUI toolkit, which can create GUI applications.IDLE is Python’s integrated development and learning environment, full name Integrated Development and Learning Environment, which is a visual shell command line, a simple command running window, and generates an IDLE shortcut in the start menu (bottom left corner of the Windows desktop) after installation.
Python test suite
Install the standard library test suite for Python, which can be used to execute written test cases,
to test whether the classes and methods written meet expectations. Whether this option is checked can be determined by demand.
py launcher The launcher is a Python launcher for Windows that helps us locate and execute different Python versions,this option is checked.
for all users (requires admin privileges)
The launcher is available for all Windows accounts. The above installation settings have checked admin privileges, whether this option is checked can be determined by demand.
All options in Image 4-3 can be checked, click next to enter the advanced options settings interface as shown in Image 4-4.
3. Advanced Options Settings
Install Python 3.11 for all users
This option can be checked according to demand.
Associate files with Python (requires the ‘py’ launcher)
File associations, associate .py files with Python (requires the installation of the Python launcher), this option is checked.
Create shortcuts for installed applications
Create shortcuts for installed applications, the created shortcuts will be displayed in the start menu, this option is checked.
Add Python to environment variables
Add Python to the system’s environment variables, this option is checked.After checking Add python.exe to PATH in the earlier steps,this option is automatically checked.
Environment variables are objects with a specific name in the operating system, containing information used by one or more applications.When the system is asked to run a program without being told the full path of the program, the system will look for the program in the current directory and also in the paths specified in the environment variable path.
System variables in the environment variable are valid for all users, while user variables are valid for the currently logged-in Windows account. When the system variable cannot be found, it will look for the current user variable.Additionally, environment variable names are case-insensitive, for example:PATH and path are the same name.
Precompile standard library
Python program code files (.py) must first be compiled into bytecode and then executed in the virtual machine.
The standard library of Python (standard library) is the built-in library that comes with Python installation (also called built-in library).Precompiling the standard library (Precompile standard library) compiles the .py files of the standard library into .pyc bytecode files during installation, so that it can be run later without recompiling, which will be faster. This option can be checked.
Download debugging symbols
Download debugging symbols, which can help debug programs and record the relationship between variables, functions, and memory locations. Whether this option is checked can be determined by demand.
Download debug binaries (requires VS 2017 or later)
Download debug binaries (requires installation of VS 2017, which is a powerful development tool launched by Microsoft),whether this option is checked can be determined by demand.
Customize install location
Custom installation path, you can specify the path to install Python.
In Image 4-4, you can check according to your needs. Here, check the first five items, specify the installation path, and then click Install to enter the Python installation progress interface as shown in Image 4-5.
Image 4-6 Python Installation Completed
Image 4-6 indicates that Python installation is complete. Click Close, and Python is now installed and ready to use.
5. Python Development Environment Tools
After installing Python, there will be a python.exe file in the installation path directory. This file is the Python interpreter, which converts Python code into bytecode and executes it. If we want to program in Python, we need development tools.
In the …\Lib\idlelib folder under the Python installation path, there is an idle.pyw file, which is the integrated development learning environment for Python programs, also known as the integrated development environment tool that comes with Python, commonly referred to as IDLE (Integrated Development and Learning Environment) tool.In the installation steps above, IDLE was checked, and after installation, an IDLE shortcut is generated in the start menu (bottom left corner of the Windows desktop).
We can use the IDLE tool for Python development, but the IDLE tool is more suitable for running and debugging some simple small programs and is not suitable for project development.
To improve project development and management efficiency, we can use the PyCharm tool for Python language development. PyCharm is a Python IDE (Integrated Development Environment) that comes with a complete set of tools to help us improve Python language development efficiency.
PyCharm provides features such as code editing, debugging, syntax highlighting, Project management, code navigation, smart suggestions, and auto-completion, helping us write Python code (i.e., Python project development) more efficiently.
Therefore, we can install PyCharm for Python development. For a detailed installation tutorial for PyCharm, please refer to the latest detailed tutorial for PyCharm installation and configuration in 2023.
Additionally, we can also install the VS Code (Visual Studio Code) code editor tool for Python development. For a detailed installation tutorial for VS Code, please refer to the latest detailed tutorial for VS Code installation and configuration in 2023.
Similar development environment tools include Sublime Text, Eclipse + PyDev, etc.
In addition, the relationship between programming languages and their development environments can refer to more detailed discussions: Compilers and C/C++ Compiler Installation.
6. Application Fields of Python
