add numbers from 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: python append n numbers to list

# Basic syntax:
your_list.extend([element]*number)
# Where:
#	- element is the element you want to add to your_list
#	- number is the number of times you want it repeated

# Note, .extend modifies your_list in place

# Example usage:
your_list = [1, 2, 3]
your_list.extend([0]*5)
print(your_list)
--> [1, 2, 3, 0, 0, 0, 0, 0]

Example 3: how to add list numbers in python

lst = []
num = int(input('How many numbers: '))
for n in range(num):
    numbers = int(input('Enter number '))
    lst.append(numbers)
print("Sum of elements in given list is :", sum(lst))
