Mapping Names to Sequence Elements in Python Using NAMEDTUPLE Library
The following Python program will map the names to the sequence of the columns and then will sum up the total.
from collections import namedtuple
Fruit = namedtuple('Fruit', ['name', 'pieces', 'price'])
def compute_cost(records):
total = 0.0
for rec in records:
s = Fruit(*rec)
total += s.pieces * s.price
return total
# Some Data
records = [
('MANGO', 10, 45),
('APPLE', 10, 50),
('ORANGE', 20, 35)
]
print(compute_cost(records))
Output:
1650.0
