Python

Functional programming (FP) is a paradigm that emphasizes immutability, pure functions, and higher-order functions. While Python, Java, and C# are all multi-paradigm languages (supporting both object-oriented and functional programming), they each have different levels of FP support. Here’s a comparison: 1. First-Class Functions All three languages support first-class functions, meaning functions can be assigned to variables, passed as arguments, and returned from other functions. Python: Full support for first-class functions using lambda, map(), filter(), reduce(), and list comprehensions. Java: Added functional support in Java 8 with lambda expressions and the Stream API. C#: Supports functional programming via delegates, lambda expressions, and LINQ (Language Integrated Query). 2. Higher-Order Functions A function is considered higher-order if it takes another function as an argument or returns one. ...

Python isn’t like Java or C# where they have explicit interface keywords. So, how do interfaces work in Python? Traditionally, Python uses a different approach. Instead of explicit interfaces, it relies on duck typing. That means if an object behaves like a duck (has the necessary methods), it’s treated as a duck, regardless of its type. Duck Typing Python relies on duck typing: If an object behaves like a duck (i.e., has the required methods/properties), it is treated as a duck. No formal interface declaration is needed. ...
