Python Programming Assessment for recruitment and development

The Python Online Test evaluates knowledge of programming in Python and commonly used parts of the Python standard library. This test includes solving live coding problems in Python and helps identify developers with the most essential Python skills.

What is a Python Test?

The Python Online Test helps hiring managers evaluate the Python skills of candidates to recruit as Python coders. Python is a general-purpose, high-level, and dynamic programming language. This Python Test enables employers to recognize and hire Python coders by measuring their skills and job readiness.

Benefits of Python Test

Using Python tests in the hiring process benefits recruiters by allowing them to assess candidates' programming skills and knowledge of Python, a widely used language in software development and data analysis. These tests enable recruiters to evaluate candidates' ability to write efficient and clean code, solve problems, and demonstrate a solid understanding of Python concepts.   

By integrating a Python test into the hiring process, recruiters can verify the candidates' proficiency levels and ensure that all shortlisted candidates possess the required skills for the role.

Where in the recruitment process should one use the Python Online Coding Test?

To help evaluate a candidate’s technical skills, the hiring managers can give them a Python Coding Test before reviewing resumés or interviewing candidates. The recruiters can use data to determine the top candidates and select interview applicants by using the Python Online Skills Test at the start of the hiring process.

Sample questions for Python Coding Test

1. What is a negative index in Python?  

Python includes a unique feature called negative indexing in Arrays and Lists. Python starts indexing from the start of a list or array or in a positive integer but reads items from the end of an array or list in a negative index.  

2. What is the Python data type SET, and how to use it?  

"set" is a Python data type, which is a collection. It's been a part of the language since Python 2.4. A set is a collection of specific and immutable items that are not in a particular sequence.  

3. What's the difference between .py and.pyc files?  

The saved Python code is contained in the .py files. The .pyc files are made when the program is integrated from another source into the current program. This file includes the bytecode for the imported Python files. The interpreter reduces processing time if one transforms the source files with the format of .py files to .pyc files.  

4. What is the distinction between a mutable data type and an immutable data type?  

The mutable Python data types, such as List, Dictionary, and Set, can be modified and changed at runtime. The immutable Python data types cannot be altered or modified, and they remain unchanged during runtime, for example, a Numeric, String, and Tuple.  

5.  What are Python namespaces?  

A namespace in Python refers to the name assigned to each object in Python. The objects are variables and functions. As each object is created, its name and space (the address of the outer function in which the object is) are made. The namespaces are maintained in Python, similar to a dictionary where the key is the namespace, and the value is the object's address.  

6. What is PYTHONPATH?  

PYTHONPATH is an environment variable used when a module is imported. Whenever a module is imported, PYTHONPATH is used to check the presence of the imported modules in numerous directories. The interpreter uses it to figure out which module to load.  

7. What are Python modules? Name some built-in modules in Python.  

Python modules refer to files containing Python code. This code can either be classes, functions, or variables. A Python module is a .py file that includes executable code. Some of the built-in modules are:  

•  os  
• data time  
• sys  
• random 
• math  
• JSON 

8. Is an indentation needed in Python?  

Indentation is needed for Python. It implies a block of code. All code within classes, loops, functions, etc, is specified inside an indented block. It is primarily done using four space characters. If the code is not indented necessarily, it will not execute accurately and throw errors.  

9. What is a lambda function?  

The lambda function refers to an anonymous function. This function can include any number of parameters but can have just one statement.  

10. What are the generators in Python?  

Generators are the kind of functions that return an iterable set of items.
