Python : Writing and Running Simple Scripts
Python allows you to run your instructions from a saved file. A file containing Python instructions is called a module. A script is a module that can be run.
By convention, Python scripts should have the file extension .py. The filename should be a valid filename, as defined by your operating system.
Creating a Script
Step 1 : Open your text editor.
Step 2 : Create a file called test1.py and insert the following code
print("---------------------------------")
print("Hello " * 5)
print("---------------------------------")
Step 3 : Save it to your working directory.
Step 4 : Open your terminal, change into the directory where the file is saved, and run the following command: python test1.py
python test1.py
Passing User Arguments to Scripts
To make a script more dynamic, you can have the user provide arguments to it when calling it
Step 1 : Create a new file called test2.py. Then, add the following code
import sys
print("This argument was passed to the script:", sys.argv[1])
Step 2 : Save and run the script as usual, passing it an argument, as illustrated here
python test2.py foobar
