One important difference between IEnumerable and List (besides one being an interface and the other being a concrete class) is that IEnumerable is read-only and List is not. ... So in your practical example, if you wanted to add the four strings one at a time, you'd need List.

Enumeration is a user defined datatype in C language. It is used to assign names to the integral constants which makes a program easy to read and maintain. The keyword “enum” is used to declare an enumeration. ... The enum keyword is also used to define the variables of enum type.

The Key Difference between a List and a Tuple. The main difference between lists and tuples is the fact that lists are mutable whereas tuples are immutable. ... A mutable data type means that a python object of this type can be modified.

Conclusion. We can conclude that although both lists and tuples are data structures in Python, there are remarkable differences between the two, with the main difference being that lists are mutable while tuples are immutable. A list has a variable size while a tuple has a fixed size.

List is an ordered sequence of elements whereas Set is a distinct list of elements which is unordered. 1) Set does not allow duplicates. List allows duplicate. Based on the implementation of Set, It also maintains the insertion Order .

What is the difference between a list and a string? While both are collections, a list differs from a string because it is mutable and can change without being reassigned. Strings are not mutable. They stay the same unless a variable is reassigned.

The enumerated, or enum, data type in Java is used to describe a specific set of values for a variable. They are static or final and type-safe. They can not change or be modified. Enum types are reference type, meaning they act like a class and can have their own constructors and methods.

Python has a great built-in list type named "list". List literals are written within square brackets [ ]. Lists work similarly to strings -- use the len() function and square brackets [ ] to access data, with the first element at index 0. ... Instead, assignment makes the two variables point to the one list in memory.

Lists are another data structure, similar to NumPy arrays, but unlike NumPy arrays, lists are a part of core Python. Lists have a variety of uses. They are useful, for example, in various bookkeeping tasks that arise in computer programming. Like arrays, they are sometimes used to store data.

Enumeration in C++ Enum is a user defined data type where we specify a set of values for a variable and the variable can only take one out of a small set of possible values. We use enum keyword to define a Enumeration.

Yes, the order of elements in a python list is persistent. In short, yes, the order is preserved. ... A list is a collection of elements that can contain duplicate elements and has a defined order that generally does not change unless explicitly made to do so.

Searching : Checking if an item (number,character,string etc) you want is present in a given list. Sorting: Arranging the items in a list in ascending or descending order. now if we search the above list for the number 6, we find it in the second position.

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.

Difference between List and Set in Java. List is a type of ordered collection that maintains the elements in insertion order while Set is a type of unordered collection so elements are not maintained any order. List allows duplicates while Set doesn't allow duplicate elements .

First() is slightly more efficient because it doesn't bother checking to see if there is a second item. The only difference is that Single() expects there to be only one item in the enumeration to begin with, and will throw an exception if there are more than one. You use .
