What is your preferred method for handling imbalanced datasets in machine learning?

1. Resampling techniques (oversampling/undersampling)
2. Synthetic data generation (SMOTE, ADASYN)
3. Algorithm-specific techniques (class weights, cost-sensitive learning)
4. Ensemble methods (bagging, boosting)
5. Other (share your approach in the comments below!) 👇👇

In today’s world,

it’s crucial to focus on leading technologies like full-stack development or AI/ML.

However, many students are just copying projects instead of learning. To succeed,

it’s important to work on real, hands-on projects and truly understand the concepts.

Has anyone went through interview for data science related roles recently? Feel free to share your experience 😄

Explain the features of Python / Say something about the benefits of using Python?

Python is a MUST for students and working professionals to become a great Software Engineer specially when they are working in Web Development Domain. I will list down some of the key advantages of learning Python:

○ Simple and easy to learn:
* Learning python programming language is easy and fun.
* Compared to other language, like, Java or C++, its syntax is a way lot easier.
* You also don’t have to worry about the missing semicolons (;) in the end!
* It is more expressive means that it is more understandable and readable.
* Python is a great language for the beginner-level programmers.
* It supports the development of a wide range of applications from simple text processing to WWW browsers to games.
* Easy-to-learn − Python has few keywords, simple structure, and a clearly defined syntax. This makes it easy for Beginners to pick up the language quickly.
* Easy-to-read − Python code is more clearly defined and readable. It's almost like plain and simple English.
* Easy-to-maintain − Python's source code is fairly easy-to-maintain.


Features of Python
○ Python is Interpreted −
* Python is processed at runtime by the interpreter.
* You do not need to compile your program before executing it. This is similar to PERL and PHP.

○ Python is Interactive −
* Python has support for an interactive mode which allows interactive testing and debugging of snippets of code.
* You can open the interactive terminal also referred to as Python prompt and interact with the interpreter directly to write your programs.

○ Python is Object-Oriented −
* Python not only supports functional and structured programming methods, but Object Oriented Principles.

○ Scripting Language —
* Python can be used as a scripting language or it can be compliled to byte-code for building large applications.

○ Dynammic language —
* It provides very high-level dynamic data types and supports dynamic type checking.

○ Garbage collection —
* Garbage collection is a process where the objects that are no longer reachable are freed from memory.
* Memory management is very important while writing programs and python supports automatic garbage collection, which is one of the main problems in writing programs using C & C++.

○ Large Open Source Community —
* Python has a large open source community and which is one of its main strength.
* And its libraries, from open source 118 thousand plus and counting.
* If you are stuck with an issue, you don’t have to worry at all because python has a huge community for help. So, if you have any queries, you can directly seek help from millions of python community members.
* A broad standard library − Python's bulk of the library is very portable and cross-platform compatible on UNIX, Windows, and Macintosh.
* Extendable − You can add low-level modules to the Python interpreter. These modules enable programmers to add to or customize their tools to be more efficient.

○ Cross-platform Language —
* Python is a Cross-platform language or Portable language.
* Python can run on a wide variety of hardware platforms and has the same interface on all platforms.
* Python can run on different platforms such as Windows, Linux, Unix and Macintosh etc.
