# Python: Find the maximum and minimum values in a given heterogeneous list using lambda

## Python Lambda: Exercise-29 with Solution

Write a Python program to find the maximum value in a given heterogeneous list using lambda.

Sample Solution:

Python Code :

``````def max_val(list_val):
max_val = max(list_val, key = lambda i: (isinstance(i, int), i))
return(max_val)

list_val = ['Python', 3, 2, 4, 5, 'version']
print("Original list:")
print(list_val)
print("\nMaximum values in the said list using lambda:")
print(max_val(list_val))
``````

Sample Output:

```Original list:
['Python', 3, 2, 4, 5, 'version']

Maximum values in the said list using lambda:
5
```

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)```
