Hello everyone, am back to discuss about a new python program. Here we learn how to sum all the elements in a list quite easily. We use a predefined function called sum()
and apply it to the list, the functions returns the sum of all the elements in a list.
Task :
To find the sum of all the elements in a list.
Approach :
- Read input number asking for length of the list using
input()
orraw_input()
. - Initialise an empty list
lst = []
. - Read each number using a
for loop
. - In the for loop append each number to the list.
- Now we use predefined function
sum()
to find the sum of all the elements in a list. - Print the result.
Program :
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))
