In the field of mathematics and computer science, the operation of summing a series of numbers is frequently encountered.

Python, a high-level, interpreted programming language, offers an effective way to compute the summation of a series. This tutorial will guide you through the process of calculating a summation series in Python.

### Step 1: Understand the Concept of Summation

In mathematics, a summation is an operation that adds together the elements of a sequence of numbers.

The result is called the total, sum, or aggregate. This is frequently symbolized using the sigma function. Furthermore, Python has a built-in **sum()** function that allows users to compute summations effortlessly.

### Step 2: Set Up Python

Ensure you have **Python** set up properly on your system. You can visit the official Python website to download and install the latest version.

You may also want to install an Integrated Development Environment (IDE) like PyCharm or Jupyter Notebook for code editing and execution.

### Step 3: Code the Summation Series in Python

Now that you understand the concept of summation and have set up Python on your system, we can now proceed to code the summation series. We will use the **sum()** function in Python.

1 2 3 4 5 6 |
# list of numbers numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] # Using sum() function total = sum(numbers) print('Sum of numbers is:', total) |

### Step 4: Python Code Execution

Upon executing the Python program, it will add all the numbers in the list and return the result.

Sum of numbers is: 55

## Here is the full code:

1 2 3 4 5 6 |
# list of numbers numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] # Using sum() function total = sum(numbers) print('Sum of numbers is:', total) |

## Conclusion

Computing the sum of an arithmetic series is one of the most common tasks you will encounter in computer science and mathematics. It’s fortunate that Python provides a built-in function called **sum()**, which calculates the sum of an iterable series swiftly and efficiently.

Through this tutorial, you have learned how to use the **sum()** function in Python to compute the sum of a number series, and this can be applied to any series of numbers, making it an exceptional resource for solving more complex tasks in Python.
