When it is required to extract strings which have successive alphabets in alphabetical order, a simple iteration, and the ‘ord’ method for Unicode representation is used.
Below is a demonstration of the same −
my_list = ["python", 'is', 'cool', 'hi', 'Will', 'How'] print("The list is :") print(my_list) my_result =  for element in my_list: for index in range(len(element) - 1): if ord(element[index]) == ord(element[index + 1]) - 1: my_result.append(element) break print("The result is :") print(my_result)
The list is : ['python', 'is', 'cool', 'hi', 'Will', 'How'] The result is : ['hi']
A list of strings is defined and is displayed on the console.
An empty list is defined.
The list is iterated over, and the Unicode character of consecutive elements in the list is compared.
If they are equal, it is appended to the empty list.
The control breaks out of the loop.
This list is displayed as the output on the console.
