python sum() code example

Example 1: python reduce()

from functools import reduce
items = [1,2,3,4,5]
sum_all = reduce(lambda x,y: x + y, items)
 
print (sum_all) #15

Example 2: sum() python

numbers = [2.5, 3, 4, -5]

# start parameter is not provided
numbers_sum = sum(numbers)
print(numbers_sum)
# output = 4.5

# start = 10
numbers_sum = sum(numbers, 10)
print(numbers_sum)
# output = 14.5

Example 3: python sum

numbers = [2.5, 3, 4, -5]

# start parameter is not provided
numbers_sum = sum(numbers)
print(numbers_sum)

# start = 10
numbers_sum = sum(numbers, 10)
print(numbers_sum)

Example 4: python sum

a = 3
b = 5
c = sum (a + b)
print(c)
