### What is Fibonacci Series?

The Fibonacci series is a sequence of numbers in which each number is the sum of the two preceding ones. It starts with 0 and 1, and from there, each subsequent number is the sum of the two previous ones. So the series goes like this: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, and so on.

Fibonacci numbers are generally used to model natural processes like the growth of plants and animals, as well as in finance to estimate future values based on past performance. As a result, they are a popular topic for study in mathematics and computer science, and thus are often used as an example in programming languages like Python.

Learning how to compute the sum of Fibonacci series using Python is a great way to learn about the language's syntax and functions, as well as its capabilities.

### Requirements before Proceeding with the Code Examples

Before diving into the exciting world of Python programming and computing the sum of Fibonacci series, there are a few requirements that you need to fulfill. Don't worry though, these requirements are simple and easy to fulfill!

Firstly, you need a computer or a laptop with Python installed. Python can be downloaded and installed for free from the official Python website. Choose the latest stable version of Python for your operating system.

Next, it is important to get familiar with Python basics. The official Python tutorial is an excellent place to start. It covers everything from syntax to data structures and functions. Work through the tutorial and practice the examples to gain a good understanding of Python fundamentals.

Another great way to learn Python is by participating in online communities. Join forums, blogs, social media groups, and Reddit threads dedicated to Python programming. This way, you can interact with experienced Python programmers, seek advice, and learn from their experiences.

Lastly, it is important to avoid common mistakes. Don't go for complex integrated development environments (IDEs) before you gain a solid understanding of Python's basic syntax and functionality. Also, don't rely too heavily on books, as they may not be up-to-date with the latest techniques and best practices in Python programming.

By following these simple steps, you will be well on your way to becoming a proficient Python programmer and unleashing the power of Python to easily compute the sum of Fibonacci series using the proven code examples presented here!

### Code Example #1: Recursion Method

Recursion in Python is a method of solving a problem where the function calls itself repeatedly until the base case is reached. In the case of the Fibonacci sequence, the base case is when the sequence reaches 0 or 1.

To compute the sum of the Fibonacci series using recursion, you can use the following code example:

```
def fibonacci(n):
if n <= 1:
return n
else:
return fibonacci(n-1) + fibonacci(n-2)
# Test the function
for i in range(10):
print(fibonacci(i))
```

In the code example above, the function `fibonacci(n)`

takes an integer `n`

as input and returns the sum of the Fibonacci series up to `n`

.

The first `if`

statement checks if `n`

is less than or equal to 1, which means we have reached the base case. If `n`

is 0 or 1, then the function simply returns `n`

.

If `n`

is greater than 1, the function calls itself twice, once with `n-1`

as the input and once with `n-2`

as the input. This is how the Fibonacci sequence is generated recursively.

To test the function, we can use a `for`

loop to iterate through the first 10 numbers in the Fibonacci sequence and print out the sum of each one using the `fibonacci()`

function.

Overall, the recursion method is a popular and effective way to compute the sum of the Fibonacci series in Python. However, it's important to note that recursion can be computationally expensive and may not be the best approach for large values of `n`

. In those cases, you may want to consider using a loop or memoization technique instead.

### Code Example #2: Iterative Method

The iterative method is a popular approach for solving the problem of computing the sum of Fibonacci series using Python. With this method, you can easily calculate the sum of the Fibonacci series by using a loop to iterate through the numbers in the series.

To use this method, you need to create a function that takes an integer n as its argument. This integer specifies the number of terms in the Fibonacci series that you want to compute.

Next, you need to create two variables, a and b, which are initialized to 0 and 1 respectively. These variables are used to keep track of the two previous numbers in the series.

You then need to create a loop that iterates from 0 to n-1, with each iteration adding up the two previous numbers in the series to get the next number. Finally, the function returns the sum of the Fibonacci series.

Here is the code example for the iterative method of computing the sum of Fibonacci series:

```
def iterative_fib_sum(n):
a, b = 0, 1
total = 0
for i in range(n):
a, b = b, a + b
total += a
return total
```

To use this code example, simply call the function with an integer argument specifying the number of terms in the Fibonacci series that you want to compute:

```
>>> iterative_fib_sum(10)
143
```

This code example is easy to understand and implement, making it an excellent choice for beginners who want to learn how to compute the sum of Fibonacci series using Python. So, feel free to experiment with this code example and see what you can come up with!

### Code Example #3: Dynamic Programming Method

The dynamic programming method is another powerful technique that can be used to compute the sum of the Fibonacci series in Python. This method involves breaking down a large problem into smaller subproblems, solving each subproblem once, and then combining the results to obtain the solution to the original problem.

To implement the dynamic programming method in Python, we can create an array to store the intermediate results of the Fibonacci series. We then initialize the first two values of the series (0 and 1) and use a loop to compute the remaining values by summing the previous two values.

Here is an example of how to use the dynamic programming method to compute the sum of the first n terms of the Fibonacci series:

```
def fib_sum(n):
fib_list = [0] * (n + 1)
fib_list[1] = 1
for i in range(2, n + 1):
fib_list[i] = fib_list[i-1] + fib_list[i-2]
return sum(fib_list)
# Example usage
print(fib_sum(5)) # Output: 12 (0 + 1 + 1 + 2 + 3 = 7)
```

In this code, we first create an array `fib_list`

of size `n + 1`

and initialize all its elements to 0. We then set the first element of the array to 1 since the first number in the Fibonacci series is 0 and the second is 1.

Next, we use a loop to calculate the remaining elements of the `fib_list`

array by adding the previous two values. Finally, we use the built-in `sum`

function to compute the sum of all the elements in the `fib_list`

array, which gives us the sum of the first `n`

terms of the Fibonacci series.

Overall, the dynamic programming method is an efficient technique for computing the sum of the Fibonacci series in Python. By breaking down the problem into smaller subproblems and using an array to store intermediate results, we can avoid redundant calculations and greatly improve the speed of our code.
