When it is required to extracts elements from a list with digits in increasing order, a simple iteration, a flag value and the ‘str’ method is used.
Below is a demonstration of the same −
my_list = [4578, 7327, 113, 3467, 1858] print("The list is :") print(my_list) my_result =  for element in my_list: my_flag = True for index in range(len(str(element)) - 1): if str(element)[index + 1] <= str(element)[index]: my_flag = False if my_flag: my_result.append(element) print("The result is :") print(my_result)
The list is : [4578, 7327, 113, 3467, 1858] The result is : [4578, 3467]
A list is defined and displayed on the console.
An empty list is defined.
The list is iterated over, and flag is set to Boolean ’True’.
Every element is first converted to list, and compared with its consecutive element.
If second element is less than or equal to first element, the flag value is set to Boolean ‘False’.
If the Boolean flag is ‘True’ in the end, the element is appended to the empty list.
This is the output that is displayed on the console.
