the output of the preceding code is as followsnow have function called % pnfuijohefg% pnfuijohand it will take two parametersone that 'll call and the other 'll call yand if happeni can actually pass in function for one of these parameters sothink about that for minute look at this example with bit more sense here% pnfuijoh  will return of yit will basically call the function with as parameterand there' no strong typing in pythonso we have to just kind of make sure that what we are passing in for that first parameter is in fact function for this to work properly for examplewe'll say print % pnfuijohand for the first parameterwe'll pass in rvbsf*uwhich is actually another functionand the number what this should do is to say do something with the rvbsf* function and the parameterand that will return rvbsf* and squared last time checked was and sure enoughthat does in fact work this might be little bit of new concept to youpassing functions around as parametersso if you need to stop for minute therewait and let that sink inplay around with itplease feel free to do so againi encourage you to stop and take this at your own pace lambda functions functional programming one more thing that' kind of python-ish sort of thing to dowhich you might not see in other languages is the concept of lambda functionsand it' kind of called functional programming the idea is that you can include simple function into function this makes the most sense with an example-bncebgvodujpotmfuzpvjomjoftjnqmfgvodujpot qsjou % pnfuijoh mbnceby the output of the above code is as followswe'll print % pnfuijohand remember that our first parameter is functionso instead of passing in named functioni can declare this function inline using the mbnceb keyword lambda basically means that ' defining an unnamed function that just exists for now it' transitoryand it takes parameter in the syntax herembnceb means ' defining an inline function of some sortfollowed by its parameter list it has single parameteryand the colonfollowed by what that function actually does 'll take the parameter and multiply it by itself three times to basically get the cube of parameter
