What is Python good for?

Any time you want to work with data, from scraping, data analysis, visualization, machine learning or AI, Python will be your best friend. There are a number of important libraries for each one of these tasks, and they are great libraries, highly used in research and production environments.

Why is Python slow?

As we know, Python is an interpreted language, while C is a compiled language. Interpreted code is always slower than direct machine code because it takes a lot more instructions in order to implement an interpreted instruction than to implement an actual machine instruction.

What was C written in?

C is a “compiled” language – and the compiler could be written in any language at all. Most C compilers are written in C – but I’d bet a good few have a bunch of C++ code in them too.
