When it is required to add the consecutive elements power, an ‘if’ condition and a simple iteration along with the ‘**’ operator are used.
Example
Below is a demonstration of the same
my_list = [21, 21, 23, 23, 45, 45, 45, 56, 56, 67]
print("The list is :")
print(my_list)
my_freq = 1
my_result = 0
for index in range(0, len(my_list) - 1):
if my_list[index] != my_list[index + 1]:
my_result = my_result + my_list[index] ** my_freq
my_freq = 1
else:
my_freq += 1
my_result = my_result + my_list[len(my_list) - 1] ** my_freq
print("The resultant value is :")
print(my_result)Output
The list is : [21, 21, 23, 23, 45, 45, 45, 56, 56, 67] The resultant value is : 95298
Explanation
A list is defined and is displayed on the console.
An integer for frequency and result are defined.
The list is iterated over, and an ‘if’ condition is placed.
It checks to see if consecutive elements are equal or not.
If they are equal, the element is multiplied with its frequency and added to the result variable.
The frequency variable is re-initialized to 1.
Otherwise, the frequency variable is incremented by 1.
This result variable is the output that is displayed on the console.
