how to sum integers in a list python code example

Example 1: how to calculate the sum of a list in python

# Python code to demonstrate the working of  
# sum() 
numbers = [1,2,3,4,5,1,4,5] 
  
# start parameter is not provided 
Sum = sum(numbers) 
print(Sum) # result is 25  
# start = 10 
Sum = sum(numbers, 10) 
print(Sum) # result is 10 +25 = 35

Example 2: Sum items in a list with ints and strings in python

def sum_mix(arr):
    sumIntStr = sum(map(int, arr))
    return sumIntStr
sum_mix(['5', '0', 9, 3, 2, 1, '9', 6, 7])
