Python program to find the Decreasing point in a List

When it is required to find the decreasing point in a list, a simple iteration and the ‘break’ statement are used.

Example

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)

Output

The list is : [21, 62, 53, 94, 55, 66, 18, 1, 0] The result is : 1

Explanation

• 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.
