If you are not sure where you installed python, the following command will help you find out. Go ahead and add python’s entire installation directory to the path of every command window.

To achieve this, you have to modify the list of directories (PATH) where windows gets programs before launching them. 'python' is not recognized as an internal or external command, operable program or batch file.ĭouble check if your computer knows where to find the interpreter. If the python command gives you the following error messages instead of launching the interpreter prompt > The thing is, your system only runs one “python” command which stops all windows after ending your interactive session with the interpreter. If your computer has a start menu as Start ‣ Programs ‣ Python 3.3 ‣ Python (command line) which opens up a command prompt > on a new window, it will also disappear after pressing the Ctrl and Z buttons. When it’s time to end your interactive session, press the “control” key, enter “z” and press “Enter” to return to your windows command prompt window. You can try it out by typing a few commands of your choice and see what happens. Most programmers use it as a convenient and highly programmable calculator. This interactive mode is one of Python’s most iconic feature. From now on, you can key in python commands, expressions, and scripts interactively and have them run as you wait. This indicates that you have launched the interpreter in “interactive mode”. Type "help", "copyright", "credits" or "license" for more information. If successfully done, you should get the following result depending on the version of python you are using.

If you already have a command prompt window open, key in the command python and press enter. Well, first and foremost, ensure that your command prompt recognizes the word “python” as a command to launch the interpreter. But how do you navigate the interpreter on the command prompt so that it can process your script? The role of this interpreter is to read the script, compile it into bytecodes, execute the bytecodes and subsequently run the program. However, for python scripts to be executable, they have to be processed by a python interpreter. Once this command prompt window has been launched, you will be on your way to running python scripts. For instance, you might get something like: After successfully launching the command, the following window should appear.ĭepending on where your system files are stored, the letter that appears might be different. Another option is entering 'cmd' in the menu search box. Under most windows versions, the menu selection process is: Start ‣ Programs ‣ Accessories ‣ Command Prompt. Technically, a command line prompt can be effortlessly launched from your computer’s start menu. And though a variety of applications can be used to create and execute python scripts, it is a little-known fact that windows command line can run these same programs regardless of the development method or tool used to create them. Python is one of the simplest and most executable programming languages used by greenhorns as they make baby steps into the world of coding.

Read on! How to run a python script on command line In this post, we are going to iron things out by showing you the difference in these systems and also teach you how to run a python script on Windows, Mac, and UNIX platforms. Confusing? Well, if you are a greenhorn in the game of coding, the whole idea can become confounding. However, the way python scripts are executed on Linux is different from the way they are “Run” on Windows or Mac. Once the interpreter is invoked, it identifies the script, reads it and then interprets it accordingly. These scripts are then saved with a “.py” extension so that the operating system can identify them as python files. Typically, python developers write stand-alone scripts that can only be executed under certain environments. Under which environments can I run a python script?

If you cannot run or execute a python script, there is no point in being a programmer.
