When it is required to remove rows with numbers, a list comprehension and the ‘not’ and ‘any’ operators are used.
Example
Below is a demonstration of the same −
my_list = [[14, 'Pyt', 'fun'], ['Pyt', 'is', 'best'], [23, 51], ['Pyt', 'fun']]
print("The list is :")
print(my_list)
my_result = [index for index in my_list if not any(isinstance(element, int) for element in index)]
print("The result is :")
print(my_result)Output
The list is : [[14, 'Pyt', 'fun'], ['Pyt', 'is', 'best'], [23, 51], ['Pyt', 'fun']] The result is : [['Pyt', 'is', 'best'], ['Pyt', 'fun']]
Explanation
A list of list is defined and displayed on the console.
A list comprehension is used to iterate over the list, and each element is checked for belonging to integer type.
The element type is checked using ‘isinstance’ method.
If it is an integer, it is removed.
Otherwise, it is stored in a list, and assigned to a variable.
This is the output that is displayed on the console.
