Python For Loop With If Filter

In this article we will show you the solution of python for loop with if filter, it is possible to traverse over a group of elements and only execute code in certain circumstances using the Python for loop with an if filter.

It offers a succinct and effective method for processing data or carrying out repetitive operations.

Every item inside the series, which will be a listing, tuple, or string, is iterated over through the for loop.

The if clear out functions as a conditional announcement that determines for each item whether or not a selected circumstance is proper or false.

If the condition is true, the corresponding block of code in the loop is executed; if no longer, it's skipped.

The use of a for loop along with an if filter provides selective data processing.

You can conduct operations on items that satisfy a requirement while excluding others that don't.

Due to its flexibility, it is especially helpful when working with huge datasets or when intricate data transformations are required. Now move to the concept of python for loop with if filter.

Step By Steps Guide On Python For Loop With If Filter :-

numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
# Print only the even numbers in the list and calculate their squares
even_numbers = []
for num in numbers:
    if num % 2 == 0:
        square = num ** 2
        print(f"The square of {num} is {square}")
# Calculate the sum of the even numbers
sum_of_even_numbers = sum(even_numbers)
print("The sum of the even numbers is:", sum_of_even_numbers)
  1. We begin with a list of named numbers ranging from 1 to 10.
  2. Our objective is to calculate the squares of all the even numbers in this list and print them.
  3. We establish an empty list called even_numbers to contain the even numbers we encounter during the loop in order to accomplish this.
  4. A for loop is used to repeatedly iterate over each num in the numbers list.
  5. We use an if statement to determine whether each integer is even and divisible by two for each number.
  6. We add num to the list of even numbers if the condition is true.
  7. After confirming that num is an even number, we use the exponentiation operator (**) to calculate its square.
  8. The square value is put into the square variable.
  9. We produce a message with f-string formatting that informs the user about the square of the current even number.
  10. For instance, we might print "The square of two is 4" if num is two. For every even number within the list, we continue inside the same manner.
  11. After the loop is completed, the overall of the even numbers inside the even_numbers list is computed.
  12. To calculate the sum of all the elements in the list, we use the sum() feature and pass even_numbers because the input.
  13. Finally, we use another print statement to output our result.
  14. For instance, we would say "The sum of the even numbers is: 30" if the total even number was 30.

Conclusion :-

Thus, we have successfully acquired the knowledge of the for loop with if filter in Python.

We also discovered that combining a for loop with an if filter creates a potent tool for selectively processing data according to predefined criteria.

It enables us to loop through a group of elements and only run code for those that meet the criteria stated in the if statement.

I hope this article on python for loop with if filter helps you and the steps and method mentioned above are easy to follow and implement.
