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

for n in range(num):
  numbers = int(input())
  lst.append(numbers)
