# Python – Extract Strings with Successive Alphabets in Alphabetical Order

PythonServer Side ProgrammingProgramming

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.

## Example

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)

## Output

The list is :
['python', 'is', 'cool', 'hi', 'Will', 'How']
The result is :
['hi']

## Explanation

• 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.
