Summation of tuples in list in Python
When it is required to sum the elements present in a list of tuple, the 'map' method and the 'sum' method can be used.
A list can be used to store heterogeneous values (i.e data of any data type like integer, floating point, strings, and so on).
A list of tuple basically contains tuples enclosed in a list.
The map function applies a given function/operation to every item in an iterable (such as list, tuple). It returns a list as the result.
The 'sum' method can be used to add the elements in an iterable.
Below is a demonstration of the same −
Example
my_list = [(11, 14), (54, 56), (98, 0), (13, 76)]
print("The list is : ")
print(my_list)
my_result = sum(map(sum, my_list))
print("The summation of tuples in a list is: ")
print(my_result)Output
The list is : [(11, 14), (54, 56), (98, 0), (13, 76)] The summation of tuples in a list is: 322
Explanation
- A list of tuple is defined, and is displayed on the console
- The iterable is mapped to the 'sum' and all the elements are summed.
- This would again be used as parameter to 'sum' method, which gives the final result.
- This is assigned to a value.
- It is displayed on the console.
