With that line, the computer knows that it should run the contents of the file as Python code using the Python interpreter. If you executed the file test.py without that line, it would look for special instruction bytes and be confused when all it finds is a text file.

This special shebang line tells the computer how to interpret the contents of the file. However, there’s a better way of doing this.įirst, we’re going to modify the script so it has an additional line at the top starting with ‘#!’ and known as a shebang (shebangs, shebangs…). To run our script, you can use the Python interpreter command and point it to the script. $ ls -1 $(which python)* | egrep ‘python($|)’ | egrep -v config One way to view the different python commands available to you is using the following command: Typically, python is a symlink to the command python2, python2 is a symlink to a command like python2.7, and python3 is a symlink to a command like python3.5.

Similar to the Windows py command, you can print out the version using the -V option.įor Linux/Mac, specifying the version of Python is a bit more complicated than Windows because the python commands are typically a bunch of symbolic links (symlinks) or shortcuts to other commands. Linux/Mac references the Python interpreter using the command python. Now, if you want to run your Python program test.py, all you have to do is run this batch file.Īw yeah! How to Run a Python Script on Linux/Mac If you find the echo helpful, just remove that line. It includes an optional line off” that prevents the py command from being echoed to the screen when it’s run.

This file simply runs your py command with the desired options. For instance, create a batch file called test.bat with the off If you don’t want to have to remember which version to use every time you run your Python program, you can also create a batch file to specify the command. For example, to run our script test.py, run the following command: X:\General Assembly\test.py), make sure your Command Prompt is in the same directory as your Python script file.
Update coderunner python full#
To avoid using the full file path to your script (i.e. To run a script, use the py command to specify the Python interpreter followed by the name of the script you want to run with the interpreter. However, the version of the default Python interpreter isn’t always consistent, so it’s best to always run your scripts as explicitly as possible. py extension is registered to run a script file with that extension using the Python interpreter. For Windows, you can just provide an option like -2.7 to run version 2.7. You can also specify the version of Python you’d like to run. Using the Command Prompt, you can use the -V option to print out the version. The default Python interpreter is referenced on Windows using the command py. Print(“Aw yeah!”)' How to Run a Python Script on Windows Our Test Scriptįor our examples, we’re going to start by using this simple script called test.py. For these examples, we’re assuming that both Python 2.7 and Python 3.5 are installed. To run a script, we have to point the Python interpreter at our Python code…but how do we do that? There are a few different ways, and there are some differences between how Windows and Linux/Mac operating systems do things. Run a script using the Python interpreter It’s important to always know which Python version is compatible with your Python code. Sometimes they’re dramatically different. The major Python version you’ll likely see is Python 2 or Python 3, but there are sub-versions (i.e. It’s critical to point out that there are different versions of the Python interpreter. Different Versions of the Python Interpreter So to run Python code, all you have to do is point the interpreter at your code. Since it’s an interpreted programming language, each line of human-readable code is passed to an interpreter that converts it to machine code at run time.

Update coderunner python series#
Traditional programming languages like C/C++ are compiled, meaning that before it can be run, the human-readable code is passed into a compiler (special program) to generate machine code – a series of bytes providing specific instructions to specific types of processors. Python is an interpreted programming language, meaning Python code must be run using the Python interpreter. As a blooming Python developer who has just written some Python code, you’re immediately faced with the important question, “how do I run it?” Before answering that question, let’s back up a little to cover one of the fundamental elements of Python.
