# Python program to print all odd numbers in a range

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

Given starting and endpoints, write a Python program to print all odd numbers in that given range.

Example:

```Input: start = 4, end = 15
Output: 5, 7, 9, 11, 13, 15

Input: start = 3, end = 11
Output: 3, 5, 7, 9, 11```

Example #1: Print all odd numbers from the given list using for loop

1. Define the start and end limit of the range.
2. Iterate from start till the range in the list using for loop and
3. check if num % 2 != 0.
4. If the condition satisfies, then only print the number.

## Python3

 `# Python program to print odd Numbers in given range` `start, end ``=` `4``, ``19` `# iterating each number in list``for` `num ``in` `range``(start, end ``+` `1``):``    ` `    ``# checking condition``    ``if` `num ``%` `2` `!``=` `0``:``        ``print``(num, end ``=` `" "``)`

Output

`5 7 9 11 13 15 17 19 `

Time Complexity: O(N)
Auxiliary Space: O(1), As constant extra space is used.

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)`

Output:

```Enter the start of range: 3
Enter the end of range: 7
3
5
7```

Time Complexity: O(N)
Auxiliary Space: O(1), As constant extra space is used.

Example #3: Taking range limit from user input or with static inputs to reduce code execution time and to increase code performance.

## Python3

 `# Uncomment the below two lines for taking the User Inputs``#start = int(input("Enter the start of range: "))``#end = int(input("Enter the end of range: "))` `# Range declaration``start ``=` `5``end ``=` `20` `if` `start ``%` `2` `!``=` `0``:` `    ``for` `num ``in` `range``(start, end ``+` `1``, ``2``):``        ``print``(num, end``=``" "``)``else``:` `    ``for` `num ``in` `range``(start``+``1``, end ``+` `1``, ``2``):``        ``print``(num, end``=``" "``)`

Output

`5 7 9 11 13 15 17 19 `

Time Complexity: O(N), Here N is the difference of the end and start.
Auxiliary Space: O(1), As constant extra space is used.

Example #4: 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: "``))` `#create a list that contains only Even numbers in given range``even_list ``=` `range``(start, end ``+` `1``)[start``%``2``::``2``]` `for` `num ``in` `even_list:``    ``print``(num, end ``=` `" "``)`

```Enter the start of range: 3
Enter the end of range: 11
3 5 7 9 11 ```

Time Complexity: O(n)
Auxiliary Space: O(n), As constant extra space is used.

## Python3

 `# Python code To print all odd numbers``# in a given range using the lambda function``a``=``3``;b``=``11``li``=``[]``for` `i ``in` `range``(a,b``+``1``):``    ``li.append(i)``# printing odd numbers using the lambda function``odd_num ``=` `list``(``filter``(``lambda` `x: (x``%``2``!``=``0``),li)) ``print``(odd_num)`

Output

`[3, 5, 7, 9, 11]`

Time Complexity: O(n)
Auxiliary Space: O(1), As constant extra space is used.

## Python3

 `def` `odd(num1,num2):``    ``if` `num1>num2:``        ``return``    ``if` `num1&``1``:``      ``print``(num1,end``=``" "``)``      ``return` `odd(num1``+``2``,num2)``    ``else``:``      ``return` `odd(num1``+``1``,num2)``num1``=``5``;num2``=``15``odd(num1,num2)`

Output

`5 7 9 11 13 15 `

Time Complexity: O(n)
Auxiliary Space: O(1), As the function is tail recursive, no stack space is used.

## Python3

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

Output

`5 7 9 11 13 15`
