data structures let' move on to data structures if you need to pause and let things sink in little bitor you want to play around with these little bit morefeel free to do so the best way to learn this stuff is to dive in and actually experimentso definitely encourage doing thatand that' why ' giving you working ipython/jupyter notebooksso you can actually go inmess with the codedo different stuff with it for examplehere we have distribution around but let' make it around jnqpsuovnqzbtoq oqsboepnopsnbm qsjou heyall my numbers changedthey're closer to nowhow about thatalrightlet' talk about data structures little bit here as we saw in our first exampleyou can have listand the syntax looks like this experimenting with lists qsjou mfo you can saycall list yfor exampleand assign it to the numbers through and these square brackets indicate that we are using python listand those are immutable objects that can actually add things to and rearrange as much as want to there' built-in function for determining the length of the list called mfoand if type in mfo that will give me back the number because there are numbers in my list just to make sureand again to drive home the point that this is actually running real code herelet' add another number in theresuch as if you run thisyou'll get because now there are numbers in that listy qsjou mfo
