What is list comprehension explain with example?

List comprehension offers a shorter syntax when you want to create a new list based on the values of an existing list. Example: Based on a list of fruits, you want a new list, containing only the fruits with the letter "a" in the name.

What do u mean by list comprehension?

A list comprehension is a syntactic construct available in some programming languages for creating a list based on existing lists. It follows the form of the mathematical set-builder notation (set comprehension) as distinct from the use of map and filter functions.

Why is it called list comprehension?

In a list or set comprehension, instead of giving the elements of the list or set explicitly, the programmer is describing what they comprehend (in the "include" sense) with an expression. Because it's a very comprehensive way to describe a sequence (a set in math and other languages, and a list/sequence in Python).

What is the list comprehension equivalent for?

List comprehension is an elegant way to define and create lists in Python. These lists have often the qualities of sets, but are not necessarily sets. List comprehension is a complete substitute for the lambda function as well as the functions map(), filter() and reduce().

What is Python comprehension list?

List comprehension in Python is an easy and compact syntax for creating a list from a string or another list. It is a very concise way to create a new list by performing an operation on each item in the existing list. List comprehension is considerably faster than processing a list using the for loop.

Is Python list comprehension faster?

It is widely believed that in Python the usage of list comprehension would always be faster than for-loops. This paper shows that it is faster, but only for simple functions used in loops. If iterations are performed over computationally expensive function, list and for-loop runtime may be almost the same.

What is faster map or list comprehension?

List comprehension is more concise and easier to read as compared to map. List comprehension are used when a list of results is required as map only returns a map object and does not return any list. Map is faster in case of calling an already defined function (as no lambda is required).

Is list comprehension a function?

List comprehension is an elegant way to define and create lists based on existing lists. List comprehension is generally more compact and faster than normal functions and loops for creating list.

What is one component of a list comprehension?

The components of a list comprehension are: Output Expression (Optional) Iterable. Iterator variable which represents the members of the iterable.

What is a list comprehension how is it useful?

Python's list comprehension is an example of the language's support for functional programming concepts. The Python list comprehensions are a very easy way to apply a function or filter to a list of items. List comprehensions can be very useful if used correctly but very unreadable if you're not careful.

What are the major differences of set comprehension vs list comprehension?

A set comprehension is similar to a list comprehension but returns a set instead of a list. The syntax is slightly different in the sense that we use curly brackets instead of square brackets to create a set. The list includes a lot of duplicates, and there are names with only a single letter.

How do you break in list comprehension?

Using break in a list comprehension

1. a one-liner.
2. no other fancy libraries like itertools, "pure python" if possible (read: the solution should not use any import statement or similar)
