Run a python code from terminal with arguments

With what python code can an argument be recognized as a string?program ran

for example:
"root:/user1/Folder1# python -W ignore run1.py Pustaka Sarawak
Govt"
In the above example, file 'run1.py' takes the argument "Pustaka Sarawak" recognizes it as a string and outputs "Govt" after performing a process. What is the code to recognize "Pustaka Sarawak" as a string? In the picture takes the Polis Diraja Malaysia and the output is 'Govt'

You can use sys library to do that.

Here is an example,

add-arg.py

import sys
num1 = sys.argv[1]
num2 = sys.argv[2]
print("The sum is ",int(num1)+int(num2))

terminal

~$ python add-arg.py 1 2
The sum is  3

Now you might see that I have used 

num1 = sys.argv[1]

Instead of

num1 = sys.argv[0]

If you put sys.argv[0] then the program name "add-arg.py' will be the argument which will be assigned to num1.

Here's an example illustrating the output due to sys.argv[0]

commandline-arg.py

import sys
name = sys.argv[0]
age = sys.argv[1]
print('Hi, ',name,' your age is ',age)

Terminal

~$ python commandline-arg.py sharon 22
Hi,  commandline-arg.py  your age is  sharon

Note: The arguments given will be taken as strings

Look into python's sys.argv function.

import sys
x = str(sys.argv[1])
y = str(sys.argv[2])

x will be Pustaka, y will be Sarawak
