Adding values with reduce() function from the list of tuples
#1
Hi,
I've been trying to use reduce() function to add values in the list of tuples. I'm only interested to add and display the numbers, but I don't know how to access and operate only on the second column(numbers)

I've tried to do it using regular function and then the reduce()

What am I doing wrong?

import functools

list = [("Rachel",19),
           ("Monica",18),
           ("Phoebe",17),
           ("Joey",16),
           ("Ross",20),
           ("Chandler",21)]

def func(self):
    x = list[0][1]
    y = list[1][1]
    return x+y

func_x = func(self="")
print(func_x)

ages_added = functools.reduce(lambda x,y:x[1][1]+y[1][1],list)
print(ages_added)
