Welcome to CF,
@Zoharra!
I'll start by answering your question on Lisp first. As stated by
@OldMan, Lisp is an old language - more specifically, an old
family of languages. Lisp has never been used in a lot of applications and it still continues to not be used a lot: originally, Lisp was used on dedicated
"Lisp machines", which ran Lisp code efficiently; in modern times, it remains mostly as a scripting language in
GNU EMACS, and it was even used in the original version of Reddit(which later went on to be rewritten in
Python).
Lisp isn't just an old language that doesn't get used in a lot of programs nowadays. It remains popular as a language among hobbyists, has several dialects that suit different needs and purposes, has a unique way of being written in(
parentheses galore!), contains many unique and interesting features(of course, these features differ across dialects), and you will also discover that the language has strong ties to AI.
I recommend you read the Wikipedia article for a quick overview on Lisp:
https://en.wikipedia.org/wiki/Lisp_(programming_language)
As for Python, you've picked up a popular language among beginners, so finding resources won't be difficult. Here are some that I recommend you check out:
- Python Crash Course by Eric Matthes - A beginner's book on Python covering all of the things you need to know.
- The official Python wiki and Python docs - You'll find a lot of information here, and even more resources.
Read through these resources carefully and you should be alright. Python is quite easy to pickup and should you have any questions, you can ask them here, on IRC, on a mailing-list, anywhere.
Welcome again!
