9. Fibonacci Series Between 0 and 50

Write a Python program to get the Fibonacci series between 0 and 50.

Note : The Fibonacci Sequence is the series of numbers :
0, 1, 1, 2, 3, 5, 8, 13, 21, ....
Every next number is found by adding up the two numbers before it.

Sample Solution:

Python Code:

# Initialize variables 'x' and 'y' with values 0 and 1, respectively
x, y = 0, 1

# Execute the while loop until the value of 'y' becomes greater than or equal to 50
while y < 50:
    # Print the current value of 'y'
    print(y)
    
    # Update the values of 'x' and 'y' using simultaneous assignment,
    # where 'x' becomes the previous value of 'y' and 'y' becomes the sum of 'x' and the previous value of 'y'
    x, y = y, x + y

Sample Output:

1                                                                                                             
1

8                                                                                                             
13                                                                                                            
21

Previous: Write a Python program that prints all the numbers from 0 to 6 except 3 and 6.
Next: Write a Python program which iterates the integers from 1 to 50. For multiples of three print "Fizz" instead of the number and for the multiples of five print "Buzz". For numbers which are multiples of both three and five print "FizzBuzz".
