5. Support for Multiple Programming Paradigms
Python supports various programming paradigms, including procedural, object-oriented, and functional programming. This flexibility allows developers to choose the best approach based on the requirements of the project.
6. Dynamic Typing
In Python, variable types are determined at runtime rather than at compile-time. This dynamic typing allows for more flexibility in code but requires careful testing to avoid type-related errors.
7. Garbage Collection
Python automatically handles memory management through its built-in garbage collector. This means developers don’t have to manually allocate or deallocate memory, which reduces the risk of memory leaks and simplifies the coding process.
