Python Math: Find the sum of the specified decimal numbers and display decimal numbers in sorted order

Python Math: Exercise-37 with Solution

Write a Python program to find the sum of the following decimal numbers and display the numbers in sorted order.

Sample Solution :-

Python Code :

from decimal import *
data = list(map(Decimal, '2.45 2.69 2.45 3.45 2.00 0.04 7.25'.split()))
print("Sum: ", sum(data))
print("Sorted order: ", sorted(data))

Sample Output:

Sum:  20.33                                                                                                   
Sorted order:  [Decimal('0.04'), Decimal('2.00'), Decimal('2.45'), Decimal('2.45'), Decimal('2.69'), Decimal('
3.45'), Decimal('7.25')]

Python: Cache results with decorators

There is a great way to cache functions with decorators in Python. Caching will help save time and precious resources when there is an expensive function at hand.

Implementation is easy, just import lru_cache from functools library and decorate your function using @lru_cache.

from functools import lru_cache

@lru_cache(maxsize=None)
def fibo(a):
    if a <= 1:
        return a
    else:
        return fibo(a-1) + fibo(a-2)

for i in range(20):
    print(fibo(i), end="|")

print("\n\n", fibo.cache_info())

Output:

0|1|1|2|3|5|8|13|21|34|55|89|144|233|377|610|987|1597|2584|4181|

 CacheInfo(hits=36, misses=20, maxsize=None, currsize=20)
