When it is required to remove characters, which are greater than ‘K’, a simple iteration is used along with the ‘ord’ (Unicode representation) method.
Below is a demonstration of the same −
my_list = ["python", "is", "easy", "to", "learn"] print("The list is :") print(my_list) K = 9 print("The value of K is ") print(K) my_result =  for element in my_list: result_string = '' for sub in element: if (ord(sub) - 97 <= K): result_string += sub my_result.append(result_string) print("The resultant list is :") print(my_result)
The list is : ['python', 'is', 'easy', 'to', 'learn'] The value of K is 9 The resultant list is : ['h', 'i', 'ea', '', 'ea']
A list with strings is defined and is displayed on the console.
The value for K is defined and is displayed on the console.
An empty list is defined.
The list is iterated over, and an empty string is created.
The elements are checked to see if difference between Unicode representation of the element and 97 is less than K.
If yes, the element is appended to empty string.
Otherwise, this string is appended to the empty list.
This is displayed as output on the console.
