# Python program to print all even numbers in a range

• Difficulty Level : Easy
• Last Updated : 27 Jan, 2023

Given starting and end points, write a Python program to print all even numbers in that given range.

Example:

```Input: start = 4, end = 15
Output: 4, 6, 8, 10, 12, 14

Input: start = 8, end = 11
Output: 8, 10```

Example #1: Print all even numbers from given list using for loop Define start and end limit of range. Iterate from start till the range in the list using for loop and check if num % 2 == 0. If the condition satisfies, then only print the number.

## Python3

 `for` `num ``in` `range``(``4``,``15``,``2``):` `  ``#here inside range function first no denotes starting, second denotes end and third denotes the interval` `    ``print``(num)`

Output

```4
6
8
10
12
14```

Example #2: Taking range limit from user input

## Python3

 `# Python program to print Even Numbers in given range`   `start ``=` `int``(``input``(``"Enter the start of range: "``))` `end ``=` `int``(``input``(``"Enter the end of range: "``))`   `# iterating each number in list` `for` `num ``in` `range``(start, end ``+` `1``):`   `    ``# checking condition` `    ``if` `num ``%` `2` `=``=` `0``:` `        ``print``(num, end``=``" "``)`

Output:

```Enter the start of range: 4
Enter the end of range: 10
4 6 8 10 ```

Example#3 Taking range limit user input and uses skip sequence number in range function which generates the all-even number.

## Python3

 `# Python program to print Even Numbers in given range`   `start ``=` `int``(``input``(``"Enter the start of range: "``))` `end ``=` `int``(``input``(``"Enter the end of range: "``))`   `#creating even starting range` `start ``=` `start``+``1` `if` `start&``1` `else` `start` ` `    `#create a list and printing element` `#contains Even numbers in range` `[ ``print``( x ) ``for` `x ``in` `range``(start, end ``+` `1``, ``2``)]`

Output:

```Enter the start of range: 4
Enter the end of range: 10
4 6 8 10 ```

## Python3

 `def` `even(num1,num2):` `    ``if` `num1>num2:` `        ``return` `    ``print``(num1,end``=``" "``)` `    ``return` `even(num1``+``2``,num2)` `num1``=``4``;num2``=``15` `even(num1,num2)`

Output

`4 6 8 10 12 14 `

## Python3

 `# Python code To print all even numbers ` `# in a given range using the lambda function` `a``=``4``;b``=``15` `li``=``[]` `for` `i ``in` `range``(a,b``+``1``):` `    ``li.append(i)` `# printing odd numbers using the lambda function` `even_num ``=` `list``(``filter``(``lambda` `x: (x``%``2``=``=``0``),li))  ` `print``(even_num)`

Output

`[4, 6, 8, 10, 12, 14]`

## Python3

 `x``=``[i ``for` `i ``in` `range``(``4``,``15``+``1``) ``if` `i``%``2``=``=``0``]` `print``(``*``x)`

Output

`4 6 8 10 12 14`

## Python3

 `a``=``4``;b``=``15``;l``=``[]` `for` `i ``in` `range``(a,b``+``1``):` `  ``l.append(i)` `print``([a ``for` `j,a ``in` `enumerate``(l) ``if` `a``%``2``=``=``0``])`

Output

`[4, 6, 8, 10, 12, 14]`

## Python3

 `a``=``4``;b``=``15` `for` `i ``in` `range``(a,b``+``1``):` `  ``if` `i``%``2``!``=``0``:` `    ``pass` `  ``else``:` `    ``print``(i,end``=``" "``)`

Output

`4 6 8 10 12 14 `

## Python3

 `# Python code To print all even numbers` `# in a given range using numpy array` `import` `numpy as np`   `# Declaring Range` `a``=``4``;b``=``15` `li``=` `np.array(``range``(a, b``+``1``))`   `# printing odd numbers using numpy array` `even_num ``=` `li[li``%``2``=``=``0``];` `print``(even_num)`

Output:

`[ 4  6  8 10 12 14]`

## Python3

 `# Python program to print even Numbers in given range` `#using bitwise & operator`     `start, end ``=` `4``, ``19`       `# iterating each number in list`   `for` `num ``in` `range``(start, end ``+` `1``):`   `    `    `    ``# checking condition`   `    ``if` `not` `(num & ``1``):`   `        ``print``(num, end ``=` `" "``)`   `#this code is contributed by vinay pinjala.`

Output

`4 6 8 10 12 14 16 18 `

Time Complexity: O(n)
