Syntax error Python program for sum of consecutive numbers with overlapping in lists

Python program for sum of consecutive numbers with overlapping in lists

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.
