Python: Multiply each number of given list with a given number using lambda function

Python Lambda: Exercise-21 with Solution

Write a Python program that multiply each number of given list with a given number using lambda function. Print the result.

Sample Solution:

Python Code :

``````nums = [2, 4, 6, 9 , 11]
n = 2
print("Original list: ", nums)
print("Given number: ", n)
filtered_numbers=list(map(lambda number:number*n,nums))
print("Result:")
print(' '.join(map(str,filtered_numbers)))
``````

Sample Output:

```Original list:  [2, 4, 6, 9, 11]
Given number:  2
Result:
4 8 12 18 22
```

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|
