A CSV file may need a second copy in another directory while the original stays available. Python’s shutil module provides file-copy functions, and shutil.copy() writes the file at the destination while leaving the source in place. I’ll show you how…
Random colors are a small exercise with a surprisingly wide footprint. They show up in test fixtures, data visualization placeholders, avatar generators, and the first 20 minutes of any Python graphics tutorial. Below are five ways to generate a random…
I recently vibe coded an entire web app just by using vibe coding, and it is going pretty well. In just a month, we were able to get 1k new users, no ads, nothing. Another recent example of vibe coding…
With the help of AI tools, it has become easier than ever to build projects, even without understanding the fundamentals of the language. This is where problems start. In interviews and exams, practical skills alone are not enough. What really…
Testing is not optional if you want to build reliable and bug-free software. It makes sure everything works as expected. In Python, PyTest is the most popular framework for this task because it is easy to use, plus supports scalable…
OOPs (Object-Oriented Programming) means writing code using objects and classes. There are four pillars of OOP: inheritance (reusing properties of a parent class), polymorphism (one interface, multiple behaviours), encapsulation (hiding data inside classes), and abstraction (showing only essential details). Python…
Python database programming isn’t just about writing queries, it’s also about understanding the right tools. From sqlite3 to MySQL and PostgreSQL (via mysql-connector-python and psycopg2), and even NoSQL with pymongo, each plays an important role. You also need a basic…
To prepare for Python Data Structures, you need a strong knowledge of core built-in types like Lists, Tuples, Sets, and Dictionaries. It is also essential to understand standard library modules such as collections and copy, along with concepts like time…
Python has become the top choice for Machine Learning because it combines simplicity with immense power. Machine Learning involves training algorithms to find patterns in data and make predictions, and Python makes this process smooth. It has specialised libraries like…
NumPy is one of the most important Python libraries for numerical computing and data analysis. It is widely used in data science, machine learning, and backend development to handle arrays, matrices, and mathematical operations efficiently. These 100 Python NumPy MCQs…
