Python: Create Fibonacci series upto n using Lambda

Python Lambda: Exercise-10 with Solution

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

Sample Solution:

Python Code :

from functools import reduce
 
fib_series = lambda n: reduce(lambda x, _: x+[x[-1]+x[-2]],
                                range(n-2), [0, 1])
 
print("Fibonacci series upto 2:")
print(fib_series(2))
print("\nFibonacci series upto 5:")
print(fib_series(5))
print("\nFibonacci series upto 6:")
print(fib_series(6))
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]

Returns all the elements of a list except the last one

Example:

def tips_initial(lst):
  return lst[0:-1]

print(tips_initial([1, 2, 3, 4]))

Output:
