we can create new list that contains two tuples so in the preceding examplewe have our tuple of and our tuple of then we make list of those two tuples and we get back this structurewhere we have square brackets indicating list that contains two tuples indicated by parenthesesand one thing that tuples are commonly used for when we're doing data science or any sort of managing or processing of data really is to use it to assign variables to input data as it' read in want to walk you through little bit on what' going on in the following examplebhfjodpnf tqmju qsjou bhf qsjou jodpnf the output to the above code is as followslet' say we have line of input data coming in and it' comma-separated value filewhich contains agessay comma-delimited by an incomesay for that agejust to make something up what can do is as each line comes ini can call the tqmju function on it to actually separate that into pair of values that are delimited by commasand take that resulting tuple that comes out of split and assign it to two variables-bhf and jodpnfall at once by defining tuple of ageincome and saying that want to set that equal to the tuple that comes out of the tqmju function so this is basically common shorthand you'll see for assigning multiple fields to multiple variables at once if run thatyou can see that the bhf variable actually ends up assigned to and jodpnf to because of that little trick there you do need to be careful when you're doing this sort of thingbecause if you don' have the expected number of fields or the expected number of elements in the resulting tupleyou will get an exception if you try to assign more stuff or less stuff than you expect to see here
