now this shouldn' be too hard there are examples in this notebook of doing all that stuffall you have to do is put it together and get it to run sothe point is not to give you something that' hard just want you to actually get some confidence in writing your own python code and actually running it and seeing it operateso please do so definitely encourage you to be interactive here so have at itgood luckand welcome to python so that' your python crash courseobviouslyjust some very basic stuff there as we go through more and more examples throughout the bookit'll make more and more sense since you have more examples to look atbut if you do feel little bit intimidated at this pointmaybe you're little bit too new to programming or scriptingand it might be good idea to go and take python revision before moving forwardbut if you feel pretty good about what you've seen so farlet' move ahead and we'll keep on going running python scripts throughout this bookwe'll be using the ipython/jupyter notebook format (which are jqzoc filesthat we've been looking at so farand it' great format for book like this because it lets me put little blocks of code in there and put little text and things around it explaining what it' doingand you can experiment with things live of courseit' great from that standpointbut in the real worldyou're probably not going to be using ipython/jupyter notebooks to actually run your python scripts in productionso let me just really briefly go through the other ways you can run python codeand other interactive ways of running python code as well so it' pretty flexible system let' take look
