Hello coders, today we are going to solve **Map and Lambda Function HackerRank Solution** in **Python**.

Contents

**Objective**

Let’s learn some new Python concepts! You have to generate a list of the first ** N** fibonacci numbers,

**0**being the first number. Then, apply the

*map*function and a

*lambda*expression to cube each fibonacci number and print the list.

**Concept**

The `map()`

function applies a function to every member of an iterable and returns the result. It takes two parameters: first, the function that is to be applied and secondly, the iterables.

Let’s say you are given a list of names, and you have to print a list that contains the length of each name.

```
>> print (list(map(len, ['Tina', 'Raj', 'Tom'])))
[4, 3, 3]
```

*Lambda* is a single expression anonymous function often used as an inline function. In simple words, it is a function that has only one line in its body. It proves very handy in functional and GUI programming.

```
>> sum = lambda a, b, c: a + b + c
>> sum(1, 2, 3)
6
```

**Note:**

*Lambda* functions cannot use the return statement and can only have a single expression. Unlike *def*, which creates a function and assigns it a name, *lambda* creates a function and returns the function itself. Lambda can be used inside lists and dictionaries.

**Input Format**

One line of input: an integer ** N**.

**Constraints**

**0 <=***N*<= 15

**Output Format**

A list on a single line containing the cubes of the first ** N** fibonacci numbers.

**Sample Input**

`5`

**Sample Output**

`[0, 1, 1, 8, 27]`

**Explanation**

The first **5** fibonacci numbers are **[0, 1, 1, 2, 3]**, and their cubes are **[0, 1, 1, 8, 27]**.

**Solution – Map and Lambda Function in Python **

cube = lambda x: x ** 3 def fibonacci(n): a, b, c = 0, 1, 1 for _ in range(n): yield a a, b = b, a + b if __name__ == '__main__': n = int(input()) print(list(map(cube, fibonacci(n))))
