Posting Etiquette
-
Ask the main part of your question in the title. This should be concise but informative.
-
Provide everything up front. Don't make people fish for more details in the comments. Provide background information and examples.
-
Be present for follow up questions. Don't ask for help and run away. Stick around to answer questions and provide more details.
-
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/

len(string) passes the object 'string' to a function 'len' that returns its length.
sting.len() (edit: hypothetically if it existed) calls the method 'len' which is an inherent part of any object of string type.
In practice the result is the same, but the latter is the more object-oriented approach.
Thanks this is helpful.
Function - probably has some limitations depending on what it is meant to do but generally I send a thing, it does it's function to that thing, and returns the result (or error).
Method - part of the thing itself. Would have to be defined for that 'object' and if it isn't then it probably doesn't make sense to ask for that info.
Probably have a ways to go to understand objects and why I would choose one VS the other.
