If the separator is not found in the string, a list containing only 1 element is returned. We used a whitespace separator in the example, but you use any other separator that suits your use case. Here is an example that splits the user-provided string on each comma.
After splitting the string, we get a list of strings, so we used the

The How do you sum items in a list in Python?Python provides an inbuilt function sum() which sums up the numbers in the list. Syntax: sum(iterable, start) iterable : iterable can be anything list , tuples or dictionaries , but most importantly it should be numbers. start : this start is added to the sum of numbers in the iterable.
How do you find the sum of a list using sum in Python?1) Using sum() Method. Example: sum(list) sum(list, start). Code Example: # Python code to explain working on sum() method # Declare list of numbers numlist = [2,4,2,5,7,9,23,4,5] numsum = sum(numlist) print('Sum of List: ',numsum) # Example with start numsum = sum(numlist, 5) print('Sum of List: ',numsum). How do you print the sum of n numbers in for loop in Python?Algorithm. Read the input (num) from the user.. Initialize a variable sum with zero.. Use a for loop to iterate from 1 to num.. Inside the loop, add the num to the sum.. At the end, print the value of the sum.. What is sum () sum () in Python?The Python sum() function calculates the total of all numerical values in an iterable. sum() works with both integers and floating-point numbers. The sum() function has an optional parameter to add a number to the total.
