Learn To Create Python3 Aliases in Windows and Ubuntu/Linux

An alias serves as a personalized shorthand or nickname for a more extended command or sequence of commands, enabling users to streamline repetitive tasks. In this guide, I will walk you through the setup of Python3 aliases on both Windows and Ubuntu/Linux systems.

Creating a Python3 Alias in Windows

On Windows, you can establish an alias by crafting a batch file to function as the alias. Follow these steps:

1. Open Notepad on your system by pressing ‘Win + R’ to launch the run dialog, typing "Notepad," and hitting Enter.

2. In Notepad, enter the following batch commands:

   @echo off
   python %*

   The '@echo off' line disables command echoing to the console, enhancing script cleanliness, while 'python %*' calls the python3 executable with any additional arguments passed to the batch file.

3. Save the file with a .bat extension, for example, python.bat.

4. Test the alias by navigating to the directory containing the Python script in the command prompt and executing 'python hello.py' (replace 'hello.py' with your script).

Creating a Python3 Alias in Ubuntu/Linux

You can format the bashrc to add an alias for python3 which will enable you call it using python.

Simple Alias Creation Using Nano:

1. Open the shell configuration file (e.g., '~/.bashrc' for Bash) in a text editor:

   nano ~/.bashrc

2. Add the following line at the end of the file:

   alias python=python3

3. Save (ctrl+o, enter) and exit (ctrl+x) the editor.

4. Reload the shell configuration with:

   source ~/.bashrc

   Now, typing 'python' will reference Python3. Verify with 'python --version'.

Using Vi Editor for Python3 Alias:

1. Open the text editor using Vi:

   vi ~/.bashrc

2. Navigate to the end of the file, press 'i' to enter insert mode, and add:

   alias python=python3

3. Exit insert mode ('Esc'), save and exit with ':wq', and press Enter.

4. Reload the shell configuration:

   source ~/.bashrc

   Now, 'python' denotes Python3.

Summary

Aliases enhance efficiency by providing shorter, memorable names for frequently used commands. This guide demonstrates the creation of a 'python' alias for Python3 on both Ubuntu/Linux and Windows using various methods. The process is more straightforward on Ubuntu/Linux. Consider applying aliases to other commands to further streamline your workflow and boost productivity.
