add all elements in list python code example

Example 1: add 1 to all elements in list python

lst = [1,2,3]
list(map(lambda x:x+1, lst))

Example 2: 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 3: python sum of list

>>> list = [1, 2, 3]
>>> sum(list)
6

Example 4: python add all values of another list

a = [1, 2, 3]
b = [4, 5, 6]
a += b
# another way: a.extend(b)

Example 5: python add all elements of a list

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))
