The Fibonacci sequence is a series of numbers where each number is the sum of the previous two numbers. So the sequence starts with the numbers 1 and 1, and then each subsequent number is the sum of the previous two.

Below we will see five different ways to generate the Fibonacci series in Python:

Using a loop:

# Function to generate the Fibonacci sequence using a loop
def fibonacci(n):
    # Initialize the sequence with the first two numbers
    sequence = [1, 1]

    # Generate the rest of the sequence
    for i in range(2, n):
        # Add the previous two numbers to get the next number in the sequence
        next_number = sequence[i - 1] + sequence[i - 2]
        sequence.append(next_number)

    return sequence

# Generate the Fibonacci sequence up to the 10th number
print(fibonacci(10))

The function starts by creating a list called “sequence” that contains the first two numbers of the Fibonacci sequence, which are 1 and 1.

Then, the function uses a loop to generate the rest of the sequence. The loop starts at the second number in the sequence (which is the third number overall) and continues until it reaches the…
