Python program to remove row with custom list element

When it is required to remove row with custom list element, a list comprehension and the ‘any’ operator are used.

Example

Below is a demonstration of the same

my_list = [[14, 3, 11], [66, 27, 8], [31, 12, 21], [11, 16, 26]]

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

check_list = [3, 10, 19, 29, 20, 15]
print("The check list is :")
print(check_list)

my_result = [row for row in my_list if not any(element in row for element in check_list)]

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

Output

The list is :
[[14, 3, 11], [66, 27, 8], [31, 12, 21], [11, 16, 26]]
The check list is :
[3, 10, 19, 29, 20, 15]
The result is :
[[66, 27, 8], [31, 12, 21], [11, 16, 26]]

Explanation

A list of integers is defined and is displayed on the console.
A list of integers is defined as ‘check_list’ and is displayed on the console.
A list comprehension is used to iterate over the elements and the ‘any’ operator is used.
Here, it is checked to see if an element in the row matches with the elements provided in the ‘check_list’
If yes, the row is stored in a list.
This is assigned to a variable.
This is displayed as output on the console.
