10. Fibonacci Series Lambda

Write a Python program to create Fibonacci series up to n using Lambda.

Sample Solution:

Python Code:

# Import the 'reduce' function from the 'functools' module
from functools import reduce

# Define a lambda function 'fib_series' that generates a Fibonacci series up to 'n' elements
# It uses the 'reduce()' function along with a lambda function and an initial list [0, 1] to generate the Fibonacci series
fib_series = lambda n: reduce(lambda x, _: x + [x[-1] + x[-2]], range(n - 2), [0, 1])

# Print the Fibonacci series up to 2 elements
print("Fibonacci series upto 2:")
print(fib_series(2))

# Print the Fibonacci series up to 5 elements
print("\nFibonacci series upto 5:")
print(fib_series(5))

# Print the Fibonacci series up to 6 elements
print("\nFibonacci series upto 6:")
print(fib_series(6))

# Print the Fibonacci series up to 9 elements
print("\nFibonacci series upto 9:")
print(fib_series(9))

Sample Output:

Fibonacci series upto 2:
[0, 1]

Fibonacci series upto 5:
[0, 1, 1, 2, 3]

Fibonacci series upto 6:
[0, 1, 1, 2, 3, 5]

Fibonacci series upto 9:
[0, 1, 1, 2, 3, 5, 8, 13, 21]
