Tuple Vs List In Python Difference Between Tuple And Lists Amit Thinks

Python List Vs Tuple Python Simplified What are the differences between lists and tuples, and what are their respective advantages and disadvantages?. Note: this is asking for the reverse of the usual tuple to array conversion. i have to pass an argument to a (wrapped c ) function as a nested tuple. for example, the following works x = myfunc.

List Vs Tuple In Python Allinpython Tuples are compared position by position: the first item of the first tuple is compared to the first item of the second tuple; if they are not equal (i.e. the first is greater or smaller than the second) then that's the result of the comparison, else the second item is considered, then the third and so on. see common sequence operations: sequences of the same type also support comparisons. in. 1 a tuple is useful for storing multiple values as you note a tuple is just like a list that is immutable e.g. once created you cannot add remove swap elements. one benefit of being immutable is that because the tuple is fixed size it allows the run time to perform certain optimizations. Named tuple instances can be referenced using object like variable dereferencing or the standard tuple syntax. they can be used similarly to struct or other common record types, except that they are immutable. they were added in python 2.6 and python 3.0, although there is a recipe for implementation in python 2.4. When multiple values are returned from a function as comma separated, they will be returned as a tuple. so obj here will be a tuple with values (s1, s2, s3, s4).

Just a note: if you need a tuple containing a variable number, you should think whether you should use a list instead. maybe a tuple is still the right choice, but usually a list would be better in this case. Consider the following expressions: new tuple(1,2); tuple.create(1,2); is there any difference between these two methods of tuple creation? from my reading it seems to be more a convenient shorthand than anything like object creation in c (heap vs stack). In normal time this could be dangerous and a specialization would be preferable. but this function is a large function, and only a small if inside change whether tuple type or not. Welcome to functional programming. you're not updating a tuple, you're creating a new tuple from an old tuple. use collections.namedtuple and it will be obvious that your're creating a new type of object from an old type of object.
