How to Run a Python Script in Terminal on Mac

Are you looking for ways to run a Python script in Terminal on your Mac? There are several methods you can use, depending on how you've set up your script. In this article, we'll explore two common ways to run a Python script from the command line.

Method 1: Using Python Command

The simplest way to run a Python script is by using the `python` command in Terminal. Simply type `python myscript.py` and press Enter. This method works as long as your Python script doesn't include a 'shebang' (a special line at the top of the file that specifies the interpreter to use). If it does, you can make the script executable by adding the necessary permissions.

Method 2: Making Script Executable

If you want to make your Python script more convenient to run, you can make it executable. To do this, use the `chmod` command followed by the `+x` flag and the name of your script, like this: `chmod +x myscript.py`. Once your script is executable, you can run it directly by typing its name in Terminal.

Running Python Script with Specific Options

Sometimes, you may want to run a Python script with specific options or flags. For example, you might want to specify the output directory or the files to process. In this case, you can use command-line arguments when running your script.

For instance, if you have a Python script that processes files with a specific naming convention (e.g., `XX.nii.gz`), you can use flags like `-s`, `-t`, and `-a` to specify the relevant files and options. Here's an example: `./pythonscript.sh -s XX -t XX.nii.gz -a XX_aparc+ -o output_dir`. This command runs your Python script with the specified options, processing only the files that match the naming convention.

Running a Python script in Terminal on Mac is easy and convenient. Whether you use the `python` command or make your script executable, you can run it quickly and efficiently. By using command-line arguments and flags, you can customize how your script runs and processes specific files. With these tips, you should be able to run your Python scripts with ease.
