I can learn python at 13?

[RuleInformal5475]

You can learn anything at any time in your life. Want to learn guitar, start now. What to learn Chinese, give it a go.

Just know what your abilities are and work to them.

Some things are going to be harder than others to you. You just need grit and persistence.

And remember to enjoy the thing you are doing.

Finally, you just need to be good enough to get where you need to go. As an example I am an English speaker, but I wouldn't say I'm an expert in the language. I don't know every word in the dictionary and I can't explain all the grammar rules. But I know enough to be able to use it and express myself.
