hi, yes, you have to create a list before all the loops and then append strings to it. ---

``` x = [] a = [] for hurra_count in range(1,4): for hip_count in range(1,3): OUT = "Hip" z = a.append(hip_count) OUT = "Hurra !" y = x.append(hurra_count) OUT = x,a ``` it is pit off,… 😕 ![2020-08-04_12h51_05](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/d/b/db8dc4c910a33cd9d7943c5e11a2cf4f4c4d2e7e.png) ---

How about this? ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/a/a/aa3f809c6bfbb4fd295e35eb87d5db354b4bd666.png) How do you paste code with indents or did you have to do it manually? ---

so it is no need to store the _strings_ in a variable, i can _append_ them direktly! and the doubling of “x” doesn`t matter, because they are in 2 diferent loops? ![2020-08-04_14h38_46](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/f/b/fb928a2e594c1fca1504aa759228b1c52e864f8f.png) ---

I’ve only been learning Python for 2 months… So my understanding is very basic… But x = [] creates a list. I’m appending (adding to the end of the list, which I have called x) on each loop. Hope this helps. 🙂 ---

I explain a little about Python in this presentation: [https://github.com/Amoursol/dynamoPython/wiki/Diving-Deeper:-A-Beginners-look-at-Python-in-Dynamo](https://github.com/Amoursol/dynamoPython/wiki/Diving-Deeper:-A-Beginners-look-at-Python-in-Dynamo) 🙂 It should be useful conceptually! Also, have a look at [https://github.com/Amoursol/dynamoPython](https://github.com/Amoursol/dynamoPython) which is a repository of 60+ Dynamo Python graphs (You can copy paste into nodes) from the community. And then check out [https://dynamopythonprimer.gitbook.io/dynamo-python-primer/](https://dynamopythonprimer.gitbook.io/dynamo-python-primer/), an awesome resource by @oliver.green! ---

Ooooo… I didn’t know about dynamo python primer!! Thankyou 🙂 ---

You are most welcome @Alien! It’s a community creation by Oliver and `super` awesome 🙂 ---
