What is the main difference between list and tuple?
The key difference between the tuples and lists is that while the tuples are immutable objects the lists are mutable. This means that tuples cannot be changed while the lists can be modified. Tuples are more memory efficient than the lists.
What is the difference between list and tuple with example?
Lists are a useful tool for preserving a sequence of data and further iterating over it. Tuple is also a sequence data type that can contain elements of different data types, but these are immutable in nature….Difference Between List and Tuple in Python:
| SR.NO. | LIST | TUPLE |
|---|---|---|
| 1 | Lists are mutable | Tuples are immutable |
What is tuple in Erlang?
A tuple is a compound data type with a fixed number of terms. Each term in the Tuple is called an element. The tuple_size is an inbuilt function defined in Erlang which can be used to determine the size of the Tuple.
What are the differences between arrays lists and tuples?
The list is an ordered collection of data types. The list is mutable….Table of Difference between List, Array, and Tuple :
| List | Array | Tuple |
|---|---|---|
| List is mutable | Array is mutable | Tuple is immutable |
| A list is ordered collection of items | An array is ordered collection of items | A tuple is an ordered collection of items |
What is the difference between dict and list?
List is a collection of index values pairs as that of array in c++. Dictionary is a hashed structure of key and value pairs. The indices of list are integers starting from 0. The keys of dictionary can be of any data type.
What is the difference between tuple and dictionary?
A tuple can contain only the predefined number of values, in dictionary there is no such limitation. A tuple can contain different values with different datatype while a dictionary can contain only one datatype value at a time. Tuples are particularly useful for returning multiple values from a function.
What is the advantage of using tuples over lists?
Advantages of Tuple Tuples are fined size in nature i.e. we can’t add/delete elements to/from a tuple. We can search any element in a tuple. Tuples are faster than lists, because they have a constant set of values. Tuples can be used as dictionary keys, because they contain immutable values like strings, numbers, etc.
Are tuples mutable Erlang?
Both of them are collection of erlang terms, and as they are not mutable as any other erlang variable, the difference is not fixed size or not.
Is Erlang a function?
A function is uniquely defined by the module name, function name, and arity. That is, two functions with the same name and in the same module, but with different arities are two different functions. Body − A clause body consists of a sequence of expressions which are separated by a comma (,).
What is difference between list tuple and dictionary is array in C is same as list in Python?
List and tuple is an ordered collection of items. Dictionary is unordered collection. List and dictionary objects are mutable i.e. it is possible to add new item or delete and item from it. Tuple is an immutable object.
Why use a tuple instead of an array?
Unlike an array, a list can have heterogeneous data. Out of all data structures, a tuple is considered to be the fastest and they consume the least amount of memory. While array and list are mutable which means you can change their data value and modify their structures, a tuple is immutable.
What is difference between list and set?
List and Set interfaces are one of them that are used to group the object. The main difference between List and Set is that Set is unordered and contains different elements, whereas the list is ordered and can contain the same elements in it.
