When it is required to multiply adjacent elements, the 'zip' method, the 'tuple' method, and the generator expression can be used.
The zip method takes iterables, aggregates them into a tuple, and returns it as the result.
Generator is a simple way of creating iterators. It automatically implements a class with '__iter__()' and '__next__()' methods and keeps track of the internal states, as well as raises 'StopIteration' exception when no values are present that could be returned.
Below is a demonstration of the same −
Example
my_tuple_1 = (7, 8, 0 ,3, 45, 3, 2, 22)
print ("The tuple is : " )
print(my_tuple_1)
my_result = tuple(i * j for i, j in zip(my_tuple_1, my_tuple_1[1:]))
print("The tuple after multiplication is : ")
print(my_result)Output
The tuple is : (7, 8, 0, 3, 45, 3, 2, 22) The tuple after multiplication is : (56, 0, 0, 135, 135, 6, 44)
Explanation
- A tuple is defined, and is displayed on the console.
- It is zipped, along with the same tuple by leaving out the first element, and is iterated over, and the corresponding elements in the tuple are multipled.
- This result is assigned to a value.
- It is displayed as output on the console.
