When it is required to sum the consecutive numbers with overlapping elements in lists, a list comprehension, list slicing, concatenation operator and ‘zip’ methods are used.
Example
Below is a demonstration of the same −
my_list = [41, 27, 53, 12, 29, 32, 16]
print("The list is :")
print(my_list)
my_result = [a + b for a, b in zip(my_list, my_list[1:] + [my_list[0]])]
print("The result is :")
print(my_result)Output
The list is : [41, 27, 53, 12, 29, 32, 16] The result is : [68, 80, 65, 41, 61, 48, 57]
Explanation
A list of integers is defined and is displayed on the console.
A list comprehension is used to iterate over the elements.
The ‘zip’ method is used to obtain specific indices of the list and concatenate them using the ‘+’ operator.
This result is converted to a list and is assigned to a variable.
This variable is displayed as output on the console.
