Python program to print odd numbers in a List
Given a list of numbers, write a Python program to print all odd numbers in given list.
Example:
Input: list1 = [2, 7, 5, 64, 14] Output: [7, 5] Input: list2 = [12, 14, 95, 3, 73] Output: [95, 3, 73]-
Using for loop : Iterate each element in the list using for loop and check if num % 2 != 0. If the condition satisfies, then only print the number.
# Python program to print odd Numbers in a List# list of numberslist1 = [10, 21, 4, 45, 66, 93]# iterating each number in listfor num in list1:# checking conditionif num % 2 != 0:print[num, end = " "]Output:
21 45 93 -
Using while loop :
# Python program to print odd Numbers in a List# list of numberslist1 = [10, 21, 4, 45, 66, 93]i = 0# using while loopwhile[i < len[list1]]:# checking conditionif list1[i] % 2 != 0:print[list1[i], end = " "]# increment ii += 1Output:
21 45 93 -
Using list comprehension :
# Python program to print odd Numbers in a List# list of numberslist1 = [10, 21, 4, 45, 66, 93]only_odd = [num for num in list1 if num % 2 == 1]print[only_odd]Output:
21 45 93 -
Using lambda expressions :
# Python program to print odd numbers in a List# list of numberslist1 = [10, 21, 4, 45, 66, 93, 11]# we can also print odd no's using lambda exp.odd_nos = list[filter[lambda x: [x % 2 != 0], list1]]print["Odd numbers in the list: ", odd_nos]Output:
Odd numbers in the list: [21, 45, 93, 11]

How to check if a list contains only odd numbers in Java
In this shot, we will discuss how to check if a list of integers contains only odd numbers in Java.
If a number is not completely divisible by two, then it is considered an odd number. For such numbers, dividing them by two always leaves a remainder of one.
If the digit of the unit place of any number belongs to 1, 3, 5, 7, or 9 then the number is odd.
Example
11 is an odd number because dividing by two leaves 1 as a remainder. It is not completely divisible by 2. The 1 in the unit place indicates the number as odd.
Solution approach
We are going to create an isListOdd[] function that takes a list of integers as input and returns true if all the elements in the list are odd. Otherwise, it returns false.
How to check if a list of integers contains only odd numbers
For this, you need to traverse through the list once and check whether each integer is completely divided by two or not. We can use a for loop or a for each loop for this. In this way, if it finds a number that is divisible by two in the list, it will simply return false.
Code
To understand this better let’s look at the code snippet.
To run the code, enter the size of the list first, followed by the elements of the list. Put a space between each integer.
Sample input: 4 3 5 7 9
Here the size of the list is four and the elements are 3, 5, 7, and 9.
