Write a Python Program to Print Odd Numbers in a List using For Loop, While Loop, and Functions with a practical example.

## Python Program to Print Odd Numbers in a List using For Loop

In this python program, we are using For Loop to iterate each element in this **list**. Inside the Python for loop, we are using the If statement to check and print odd numbers.

# Python Program to Print Odd Numbers in a List NumList = [] Number = int(input("Please enter the Total Number of List Elements: ")) for i in range(1, Number + 1): value = int(input("Please enter the Value of %d Element : " %i)) NumList.append(value) print("\nOdd Numbers in this List are : ") for j in range(Number): if(NumList[j] % 2 != 0): print(NumList[j], end = ' ')

**OUTPUT**

**ANALYSIS**

User entered elements = [3, 4, 5, 9]

**For Loop – First Iteration: **for 0 in range(0, 4)

The condition is True. So, it enters into the If Statement

if(NumList[0] % 2 != 0) => if(3 % 2 != 0) – Condition is True

This Number printed.

**Second Iteration:** for 1 in range(0, 4) – Condition is True

if(NumList[1] % 2 != 0) => if(4 % 2 != 0) – Condition is False

This Number Skipped.

**Third Iteration:** for 2 in range(0, 4) – Condition is True

if(NumList[2] % 2 != 0) => if(5 % 2 != 0) – Condition is True

This Number printed.

**Fourth Iteration:** for 3 in range(0, 4) – Condition is True

if(9 % 2 != 0) – Condition is True

This Number also printed.

**Fifth Iteration:** for 4 in range(0, 4) – Condition is False

So, it exits from For Loop

## Python Program to Print Odd Numbers in a List using While loop

This Python program for odd numbers in a list is the same as the above. We just replaced the For Loop with While loop.

# Python Program to Print Odd Numbers in a List NumList = [] j = 0 Number = int(input("Please enter the Total Number of List Elements: ")) for i in range(1, Number + 1): value = int(input("Please enter the Value of %d Element : " %i)) NumList.append(value) print("\nOdd Numbers in this List are : ") while(j < Number): if(NumList[j] % 2 != 0): print(NumList[j], end = ' ') j = j + 1

**OUTPUT**

## Python Program for Odd Numbers in a List using Functions

This Python odd numbers in a list program is the same as the first example. However, we separated the logic using Functions

# Python Program to Print Odd Numbers in a List def odd_numbers(NumList): for j in range(Number): if(NumList[j] % 2 != 0): print(NumList[j], end = ' ') NumList = [] Number = int(input("Please enter the Total Number of List Elements: ")) for i in range(1, Number + 1): value = int(input("Please enter the Value of %d Element : " %i)) NumList.append(value) print("\nOdd Numbers in this List are : ") odd_numbers(NumList)

**OUTPUT**
