Dec 4, 2013 · sum & len are built-in methods on list s & do exactly as their name says. The str.lower() method converts a string to lower-case completely. How about while num.lower() != 'stop'? That would account for your three plus any other weird case issues. @thumbtackthief I did consider that, but somehow messed it up at the end. Code needs a lot of edit.

Mar 14, 2022 · To sum numbers in python, we can declare a function to add two values, and call the same to add another value to the return value of the function. Below is an example of how we can use the recursion function. theSum = 0 for i in numTotal: theSum = theSum + i. return theSum. print(total([1,3,5,7,9]))

Jan 23, 2025 · One of the most common use cases of the sum function is to add up the elements of a list of numbers. Here's a simple example: In this example, we create a list of numbers and then use the sum function to calculate their sum. The output will be 15, which is the sum of 1 + 2 + 3 + 4 + 5. The sum function works equally well with tuples.
