Certainly! If you're working in an environment where python refers to an older version like Python 2.x, and you want it to point to python3 instead, you can create an alias or change the symbolic link to achieve this. Here's a step-by-step tutorial for Linux-based systems:
Firstly, confirm the versions of Python installed on your system. Open a terminal and type:
This will display the versions currently assigned to python and python3.
An alias is a way to create shortcuts or alternate names for commands. Open your terminal and enter:
This will temporarily set python to point to python3 for your current terminal session. However, this change won't persist after you close the terminal.
To make this change permanent, you can add the alias command to your shell configuration file (e.g., .bashrc, .bash_profile, .zshrc, etc.):
Replace .bashrc with your respective shell configuration file if you're using a different shell.
Alternatively, you can update the symbolic link itself. Find the location of python and python3:
Then, you can remove the current python link and create a symbolic link to python3:
This method directly modifies the link, but exercise caution when using sudo to avoid unintended system changes.
Finally, to ensure that python now points to python3, execute:
This command should display the version of Python 3.x, indicating that python now refers to python3.
Changing the default python version might affect system applications that rely on Python 2.x. Always be cautious, and consider using a virtual environment or explicitly specifying the Python version for specific projects.
Remember, altering system configurations may require administrative privileges (sudo), so proceed with caution and verify commands before executing them.
This tutorial guides you through making python point to python3 on Linux-based systems, ensuring a smoother transition between Python versions.
