Day 22 : Python Program to Print All Integers that are 'not Divisible by Either 2 or 3

 

def print_not_divisible_by_2_or_3(start, end):

    print(f"Integers between {start} and {end} not divisible by 2 or 3:")

    for num in range(start, end + 1):

          if num % 2 != 0 and num % 3 != 0:

            print(num, end=' ')

    print()  

start = int(input("Enter the start of the range: "))

end = int(input("Enter the end of the range: "))

print_not_divisible_by_2_or_3(start, end)

Code Explanation:

1. Function Definition:

def print_not_divisible_by_2_or_3(start, end):

This defines a function named print_not_divisible_by_2_or_3, which takes two arguments:

start: The starting number of the range.

end: The ending number of the range.

2. Print a Header:

print(f"Integers between {start} and {end} not divisible by 2 or 3:")

This line prints a message indicating the range of numbers that will be checked.

3. Loop Through the Range:

for num in range(start, end + 1):

This loop iterates through all integers from start to end (inclusive).

range(start, end + 1) generates the sequence of numbers within this range.

4. Check the Condition:

if num % 2 != 0 and num % 3 != 0:

num % 2 != 0: Checks if the number is not divisible by 2 (i.e., it's odd).

num % 3 != 0: Checks if the number is not divisible by 3.

The condition ensures the number meets both criteria (not divisible by either 2 or 3).

5. Print Numbers Meeting the Condition:

print(num, end=' ')

If the condition is met, the number is printed on the same line.

end=' ' ensures the numbers are printed with a space instead of a newline after each.

6. End of Function:

print()

After the loop completes, this adds a newline to separate the output from subsequent program output.

Main Program:

start = int(input("Enter the start of the range: "))

end = int(input("Enter the end of the range: "))

The user is prompted to input the starting (start) and ending (end) numbers of the range.

int(input(...)) ensures the input is converted from a string to an integer.

Call the Function:

print_not_divisible_by_2_or_3(start, end)

The function is called with start and end as arguments, performing the checks and printing the results.
