How do we use Python in script mode?

Python is a high level programming language that helps a user to run a program and integrate systems more efficiently; as it executes a program in comparatively fewer lines of code. In this programming language, a code can be run in two ways−

• Interactive mode, and

• Script mode

In this article, we will learn how to execute a python code in a script mode.

Python in Script Mode

A script mode in Programming languages is nothing but putting all the lines of code in a python program into a file, also known as a script, and using Python to run the file. Python in script mode can be run in various applications containing Python IDE; and also through a Terminal or Command Prompt.

In applications supporting Python, the scripts can be created and executed in the environment itself.

However, to execute a Python code in script mode using command line, one must follow the following command syntax −

C:\users>python filename.py

Here, filename.py is just a placeholder for the file containing the Python lines of code.

Example

Let us see an example to execute a Python code in a file, through the Command Prompt in Windows.

Assume we have a Python code in a file named ‘test.py’ –

#!/usr/bin/python
print ("Hello World")

Make sure your system has python installed in it before executing the following command to execute the ‘test.py’ file −

C:\users>python test.py

The output is displayed as follows −

Hello World
