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.
