Python – Filter rows with Elements as Multiple of K
When it is required to filter rows with elements which are multiples of K, a list comprehension and modulus operator are used.
Example
Below is a demonstration of the same −
my_list = [[15, 10, 25], [14, 28, 23], [120, 55], [55, 30, 203]]
print("The list is :")
print(my_list)
K = 5
print("The value of K is ")
print(K)
my_result = [index for index in my_list if all(element % K == 0 for element in index)]
print("The result is :")
print(my_result)Output
The list is : [[15, 10, 25], [14, 28, 23], [120, 55], [55, 30, 203]] The value of K is 5 The result is : [[15, 10, 25], [120, 55]]
Explanation
A list of list is defined and displayed on the console.
The value for ‘K’ is defined and displayed on the console.
A list comprehension is used to iterate over the list, and modulus of each element with K is compared to 0.
The ‘all’ operator is used to check the output based on all elements.
If the value is ‘True’, this is assigned to a variable.
This is the output that is displayed on the console.
