python Command: Tutorial & Examples
Run Python scripts
python command is used to execute Python scripts in a shell. It can
be used to launch a Python interactive console, or to run a Python script from a file. It is a high-level, interpreted,
interactive, and object-oriented programming language.
python Command Works
python command works by calling the Python interpreter to execute a Python script. When you type
by the name of a Python script at the command line, the Python interpreter reads and interprets the script, then
performs the actions defined in the script.
python Command Is Used For
python command is used to run Python scripts, which can range from simple scripts to automate tasks on a server,
to complex applications. Python is often used for web development, data analysis, artificial intelligence, and more.
python command is essential for running applications and services that are written in Python.
python Command Is Important
Python is one of the most popular programming languages because of its simplicity and versatility. The
is the gateway to running Python scripts and applications on a Linux server, making it a vital command for many server
administrators and developers.
How To Use The
To use the
python command, simply type
python at the command line, followed by the name of the Python script you
want to run. For example:
This will run the script
my_script.py with the Python interpreter.
You can also start an interactive Python console by simply typing

And to run a library module as a script, you could run:
python -m http.server
Potential Problems And Pitfalls With The
One potential issue with the
python command is that there are two major versions of Python in use: Python 2 and
Python 3. Some scripts written for Python 2 will not work correctly with Python 3, and vice versa.
Therefore, you might need to specify the version of Python you want to use when running a script. You can do this by
python3 instead of just
python. For example:
Another common problem is getting a
FileNotFoundError when trying to run a script. This usually means that the script
does not exist at the location you specified. Make sure you're in the correct directory and that the script name is
In conclusion, the
python command is a powerful tool for running Python scripts and applications on a Linux server.
With its help, you can automate tasks, run web applications, and much more. Understanding how to use it effectively is
an important skill for any Linux user.
