Python: Sort a list of tuples using Lambda
Python Lambda: Exercise-3 with Solution
Write a Python program to sort a list of tuples using Lambda.
Python Code :
subject_marks = [('English', 88), ('Science', 90), ('Maths', 97), ('Social sciences', 82)] print("Original list of tuples:") print(subject_marks) subject_marks.sort(key = lambda x: x) print("\nSorting the List of Tuples:") print(subject_marks)
Original list of tuples: [('English', 88), ('Science', 90), ('Maths', 97), ('Social sciences', 82)] Sorting the List of Tuples: [('Social sciences', 82), ('English', 88), ('Science', 90), ('Maths', 97)]

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())
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)
