Python | Accumulative index summation in tuple list
Sometimes, while working with data, we can have a problem in which we need to find accumulative summation of each index in tuples. This problem can have application in web development and competitive programming domain. Let’s discuss certain way in which this problem can be solved.
Method : Using
accumulate() + sum() + lambda + map() + tuple() + zip()
The combination of above functions can be used to solve this task. In this, we pair the elements using
zip(), the then we perform the sum of them and we extend this to all elements using
map(). The taking forward of sum is done by using accumulate. The binding of all logic is done by lambda function.
The original list : [(3, 4, 5), (4, 5, 7), (1, 4, 10)] Accumulative index summation of tuple list : [(3, 4, 5), (7, 9, 12), (8, 13, 22)]
