You need to dedent the return statement so that it falls outside the loop: def addNumbers(num) sum=0 for i in range(0,num+1) sum=sum+i return sum

Dec 8, 2013 · Do not call your variable sum; that's the name of a built-in function. (And you might want to type help(sum) at the interpreter console, because it may help you here.) How about this: total += i. totaltotal += total. print total, totaltotal. Alternatively, you can make a list of the totals and store them to operate on separately: total += i.

Apr 9, 2024 · Use a for loop to iterate over a sequence of numbers. Reassign the variable to its value plus the current number. total += num. print(total) # 👉️ 20. We used a for loop to sum the numbers in a list. The first step is to declare a new variable and initialize it to 0.

In this article, we will explore how to write a Python program to calculate the sum of n numbers using a for loop. This program is a fundamental exercise that showcases the use of loops in Python and helps us understand the iterative nature of programming.

Dec 6, 2024 · Another method to add values is by using extend () method. This method is used to add multiple values at once to a list. The += operator allows us to add items from one list to another. This can be useful when you want to add multiple values. We can also use a while loop to add values to a list.

May 30, 2024 · The most obvious way to add numbers stored in a list is to use a for-loop. The following code fragment visits each list element in order and totals the sum of its elements. For example, look at the logic of the code below. # Add the current sale to the running total. total_sales += sale.

Apr 7, 2019 · My homework assignment is to calculate the sum of a series of numbers inputted by the user using a 'For Loop', but I can't seem to successfully add the input numbers.

Summing numbers in a loop is a fundamental programming task. This guide explores various techniques for calculating sums using both for and while loops in Python, covering different scenarios like summing items from a list, numbers in a …

Dec 22, 2021 · Here’s an example of how you can calculate the sum of the first n numbers using a for loop in Python: # Input the value of n n = int(input("Enter a positive integer: ")) # Initialize …

In this article, we explored various methods of adding up numbers in Python using loops. We covered adding numbers using for loops, while loops, while True loops, and user input.
