Python – Filter Tuples Product greater than K

When it is required to filter tuples product greater than K, a list comprehension is used.

Example

Below is a demonstration of the same −

def tuples_product(index):
   my_result = 1
   for element in index:
      my_result *= element
   return my_result

my_list = [(14, 25, 17), (2, 3, 5), (81, 42, 21), (6, 2, 1)]

print("The list is :")
print(my_list)

K = 15
print("The value of K is :")
print(K)

my_result = [index for index in my_list if tuples_product(index) > K]

print("The result is :")
print(my_result)

Output

The list is :
[(14, 25, 17), (2, 3, 5), (81, 42, 21), (6, 2, 1)]
The value of K is :
15
The result is :
[(14, 25, 17), (2, 3, 5), (81, 42, 21)]

Explanation

• A method named ‘tuples_product’ is defined that takes tuple as a parameter and returns the product of every element in the tuple as output.

• Outside the method, a list is defined and displayed on the console.

• The value for key is defined and is displayed on the console.

• A list comprehension is used to iterate over the list, and for every element, the method is called.

• The method’s result is compared to K.

• If it is greater than K, it is added to a list and is assigned to a variable.

• This is the output that is displayed on the console.
