part igetting started with python telling the computer what to do pythonlike every other programming language in existencerelies on commands command is simply step in procedure in you saw how "get the bread and butter from the refrigeratoris step in procedure for making toast when working with pythona commandsuch as print()is simply the same thinga step in procedure to tell the computer what to doyou issue one or more commands that python understands python translates these commands into instructions that the computer understandsand then you see the result command such as print(can display the results onscreen so that you get an instant result howeverpython supports all sorts of commandsmany of which don' display any results onscreen but still do something important as the book progressesyou use commands to perform all sorts of tasks each of these tasks will help you accomplish goaljust as the steps in procedure do when it seems as if all the python commands become far too complexsimply remember to look at them as steps in procedure even human procedures become complex at timesbut if you take them one step at timeyou begin to see how they work python commands are the same way don' get overwhelmed by theminsteadlook at them one at time and focus on just that step in your procedure telling the computer you're done at some pointthe procedure you create ends when you make toastthe procedure ends when you finish buttering the toast computer procedures work precisely the same way they have starting and an ending point when typing commandsthe ending point for particular step is the enter key you press enter to tell the computer that you're done typing the command as the book progressesyou find that python provides number of ways to signify that stepgroup of stepsor even an entire application is complete no matter how the task is accomplishedcomputer programs always have distinct starting and stopping point seeing the result you now know that command is step in procedure and that each command has distinct starting and ending point in additiongroups of commands and entire applications also have distinct starting and ending
