How can I execute a Python file that has been compiled into a .pyc format on my Ubuntu system?

I’ve been trying to run a Python file that’s in .pyc format on my Ubuntu system, but I’m kind of stuck. So, here’s the situation: I had this Python script I was working on and I compiled it to a .pyc file for some reason—maybe I thought it would run faster or something? I honestly can’t remember. Anyway, now I’m not exactly sure how to execute this .pyc file.

I know that typically, you’d just run a .py file by using the command `python3 filename.py`, but since this time it’s a .pyc file, I’m not sure if that approach will still work. I was poking around online and saw a few mentions of using the `python` command along with the filename, but I’m concerned I might mess something up or there could be additional steps involved.

Also, do I need to worry about the Python version? Like, if I compiled this .pyc file with Python 3.8, do I need to make sure I’m still using that version to run it? Or can I run it with a more recent version? I’m just trying to avoid any runtime errors that could happen due to version conflicts.

Another thing that’s been bugging me is where this .pyc file is located. If it’s in a subdirectory or something, do I need to navigate to that directory through the terminal first, or can I just point directly to the .pyc file location when I run the command? It’s honestly a bit confusing, and I don’t want to end up in a rabbit hole of issues.

If anyone has a straightforward way to run this .pyc file on Ubuntu without causing too many headaches, I would really appreciate it. I’m ready to get this thing running so I can jump back into the project, but I want to make sure I do it right. Any tips, tricks, or personal experiences you guys can share would be awesome! Thanks in advance!

    1. Running a .pyc file on Ubuntu

      Running a .pyc File on Ubuntu

      So, it sounds like you have a .pyc file and you’re not really sure how to run it. No worries, it’s pretty straightforward! You can actually run a .pyc file using Python just like you would with a .py file, using the command: 

      python filename.pyc

      If you’re using Python 3, you might want to be careful and use python3 instead, like this: 

      python3 filename.pyc

      Now, about the Python version—you should definitely use the same version that your .pyc file was compiled with. So if you compiled it with Python 3.8, you’d want to run it with Python 3.8 too. Running it with a different version could lead to errors, as .pyc files can be version-specific.

      As for the location, you’re right that it can be a bit tricky. If your .pyc file is located in a subdirectory, you’ll have to navigate to that directory first, or you can just specify the full path to the file. For example: 

      python3 /path/to/your/file/filename.pyc

      So, either navigate to the directory using cd /path/to/your/directory or just directly run the command with the full path as shown above.

      Just remember, keep it simple: use the right Python version and point to the right file location. That should help you avoid any issues! Good luck, and I hope you get it running smoothly!


    2. To execute a .pyc file on your Ubuntu system, you can use the `python` command similarly to how you run a .py file. Specifically, you would use a command like `python3 path/to/your_file.pyc`. It’s important to ensure that you have the appropriate Python version installed that matches the version used to compile the .pyc file. If your .pyc file was created using Python 3.8, it’s best to run it with Python 3.8 or a compatible newer version to avoid potential runtime errors. Generally, the Python 3.x versions maintain backward compatibility, but it’s always safer to match versions if you encounter issues.

      Regarding the location of your .pyc file, you can either navigate to the directory containing it using the terminal or directly specify the full path to the .pyc file in your command. For example, if your file is located in a subdirectory called `my_scripts`, you could run it by specifying the full path: `python3 /path/to/my_scripts/your_file.pyc`. This flexibility means you don’t necessarily need to change directories beforehand; just ensure that you provide the correct path to the command. Following these steps should allow you to run your .pyc file without encountering major obstacles.
