When it is required to find the decreasing point in a list, a simple iteration and the ‘break’ statement are used.
Below is a demonstration of the same −
my_list = [21, 62, 53, 94, 55, 66, 18, 1, 0] print("The list is :") print(my_list) my_result = -1 for index in range(0, len(my_list) - 1): if my_list[index + 1] < my_list[index]: my_result = index break print("The result is :") print(my_result)
The list is : [21, 62, 53, 94, 55, 66, 18, 1, 0] The result is : 1
A list of integers is defined and is displayed on the console.
An integer variable is assigned a value.
The list is iterated over, and the elements in consecutive indices are checked.
If the second index is less than first, the index is assigned to the integer variable.
The control breaks out of the loop.
This is the output that is displayed on the console.
