They help you gain hands-on experience with real-world applications and generally take 2–6 weeks to complete. Intermediate projects are designed for those with a basic understanding of Python who want to tackle more complex problems. Create an educational AR app that overlays interactive elements on textbooks or flashcards. This project is practical for understanding version control data and using APIs effectively.
A function that takes variable arguments is called a function prototype. This __name__ variable is a special built-in variable that points to the name of the current module. This can be done by defining user-defined main() function and by using the __name__ property of python file. But this doesn’t mean that we cannot simulate the execution of main.
When visualizing data with Matplotlib, you can customize every aspect of the plot, including titles, axes, colors, and annotations. With Pandas, tasks such as merging datasets, handling missing values, and pivoting tables become straightforward. Pandas, a powerful library for data manipulation in Python, offers advanced functionalities for handling complex datasets efficiently.
Essential Interview Questions for Senior Python Developers
- It’s important to set specific goals for your Python interview preparation based on your skill and type of role you’re interviewing for.
- } Python implementations (including CPython) include a read–eval–print loop (REPL); this permits the environment to function as a command line interpreter, with which users enter statements sequentially and receive results immediately.
- Once a tuple is created, its elements cannot be altered, providing a stable and unchanging dataset.”
- In this module, you’ll explore key architectural styles used in distributed systems, including client-server, peer-to-peer, layered, and microservices models.
- Develop the technical foundation to design and implement scalable, interconnected cloud systems.
- These projects typically take 5–8 weeks and provide a strong portfolio to demonstrate advanced Python skills.

I prefer Educative courses because they have a nice mix of text & images. Your method is simple, straight to the point and I can practice with it everywhere, even from my phone, that’s something I have never had in other learning platforms. Learn and practice the Backtracking and Subsets patterns to solve coding interview problems. The ability to efficiently evaluate the tradeoffs between time and space complexity in different solutions The ability to identify the underlying patterns of 2800+ LeetCode style coding questions by assessing the problem statement (and learn the tricks required to solve it)

Basic Python interview questions
The location where we can find a variable and also access it if required is called the scope of a variable. Instead of passing values or references directly, Python passes a reference to the object. Python uses Pass by Object Reference (also called Call by Object Sharing) to pass arguments to functions. These arguments are collected into a dictionary, where the https://uvik.io/ keys are the argument names and the values are the corresponding values. In the example, we defined a lambda function(upper) to convert a string to its upper case using upper().
I use mocking libraries like unittest.mock to isolate dependencies and run tests frequently through CI/CD pipelines to ensure code reliability. In large codebases, I ensure consistent exception structure using base exception classes and apply exception handling close to the source of the error to maintain code readability and traceability. Designing with immutability and leveraging concurrent data structures helps avoid race conditions and data corruption. I create a requirements.txt file that lists all the packages and their versions required by the project, which allows consistent setup across environments. This is especially useful when creating custom iterable objects such as paginated APIs or custom data loaders. Additionally, I use generators, __slots__, and batching techniques to reduce the memory footprint.
