Python Scripting Interview Questions
Python scripting interview questions typically focus on a candidate's understanding of fundamental Python concepts as well as their ability to write efficient and clean scripts to solve real-world problems. Common topics include data types, control flow, functions, modules, packages, error handling, file handling, and object-oriented programming. Interviewers may also inquire about the candidate's experience with popular Python libraries and frameworks, such as NumPy, Pandas, or Flask. Additionally, candidates may be asked to walk through their thought process when presented with coding challenges or troubleshooting scenarios, demonstrating their problem-solving skills and coding proficiency.

1 - What is Python scripting?
Python scripting involves writing small programs or scripts using the Python programming language to automate tasks, manipulate data, or perform specific actions based on user requirements.
2) What are the advantages of using Python for scripting?
Python is a high level, interpreted language with a simple and readable syntax, making it easy to learn and use for scripting purposes. It has a wide range of libraries and frameworks available, which can be leveraged for various tasks without having to write code from scratch. Python also offers platform independence, portability, and compatibility with different operating systems, making it versatile for scripting on different platforms.
3) How can you execute a Python script?
A Python script can be executed using the command line by typing “python scriptname.py” or by making the script executable and running it directly. In Unix like systems, you can add a shebang line at the beginning of the script (#!/usr/bin/env python) to specify the Python interpreter to be used.
4) How do you pass arguments to a Python script?
You can pass arguments to a Python script by using the sys module's argv attribute, which provides access to command line arguments. Alternatively, you can use the argparse module for more advanced argument parsing, allowing for options, flags, and help messages to be defined and processed easily.
5) What is the purpose of shebang in a Python script?
The shebang line at the beginning of a Python script (#!/usr/bin/env python) specifies the interpreter that should be used to execute the script. It allows the script to be executed directly from the command line, without explicitly invoking the Python interpreter.
6) How can you handle exceptions in Python scripting?
Exceptions in Python scripting can be handled using try except blocks to catch and handle errors gracefully. By wrapping code that may raise exceptions in a try block and specifying the exception type to catch in an except block, you can control the flow of the script and provide error messages or take alternative actions when exceptions occur.
7) How can you interact with files in Python scripting?
Python provides built in functions and modules like open(), read(), write(), and close() for interacting with files in Python scripts. By using these functions along with proper error handling and file manipulation techniques, you can read, write, and manipulate files for various scripting tasks.
8) What are some common use cases for Python scripting?
Python scripting can be used for tasks such as automating repetitive processes, data analysis and manipulation, web scraping, system administration, text processing, and building simple utilities and tools for various applications. Its versatility and ease of use make it a popular choice for scripting across different domains.
In conclusion, Python scripting is a powerful tool that offers a wide range of capabilities for automation and customization. By leveraging its simplicity, extensive libraries, and community support, developers can efficiently script various tasks to improve productivity and streamline workflows.
