Posting Etiquette

  1. Ask the main part of your question in the title. This should be concise but informative.

  2. Provide everything up front. Don't make people fish for more details in the comments. Provide background information and examples.

  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/

Just started learning python - question about types of statements. (self.learn_programming)

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?

Clearly you meant:

string = "foobar"
length = 0
_ = [length += 1 for _ in string]
print(length)

Much more readable!

Edit: Damn, doesn't work, was hoping to make something cursed but you can't make an assignment during comprehension. Oh well, maybe Python 3.14!
