Just started as in, I'm about an hour into a 4 hour intro video. Seeing two basic ways of manipulating things and don't understand the difference.

If I want to know the length of a string and I just guess at how to do it I would try one of these two things,

  1. Len(string)
  2. string.len()

What is the difference between these types of statements? How do I think about this to know which one I should expect to work?

The first one is the approach of Functional Programming language (e.g. Python ) and the second one is the approach for Object orientated languages (e.g. Java, C#)

Python is not a functional language. It's highly imperative. For example if-else is a statement, not an expression.

An obvious counter-example is Rust which uses .len() and is a quite functional language (much more than Python).

Also object oriented languages aren't the "opposite" of functional languages. Guess what the O stands for in OCaml.

Rust is Object Orientated Language.

Python is a function Orientated Language. ( Python 3 is less but its still has that orientation )
Because python is a scripting language and their Object Orientated Features are not that expanded like a "normal" Object Orientated Language like C# or Java.

  3. Be present for follow up questions. Don't ask for help and run away. Stick around to answer questions and provide more details.

  4. Ask about the problem you're trying to solve. Don't focus too much on debugging your exact solution, as you may be going down the wrong path. Include as much information as you can about what you ultimately are trying to achieve. See more on this here: https://xyproblem.info/
