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]

Python: Tips of the Day

Combines two lists into a dictionary, where the elements of the first one serve as the keys and the elements of the second one serve as the values. The values of the first list need to be unique and hashable:

Example:

def tips_to_dictionary(keys, values):
  return {key:value for key, value in zip(keys, values)}
print(tips_to_dictionary(['x', 'y'], [5, 10]))

Output:

{'x': 5, 'y': 10}
