Python: Find the maximum 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: Tips of the Day

Inverts a dictionary with non-unique hashable values:

Example:

def tips_collect_dictionary(obj):
  inv_obj = {}
  for key, value in obj.items():
    inv_obj.setdefault(value, list()).append(key)
  return inv_obj
ages = {
  "Owen": 25,
  "Jhon": 25,
  "Pepe": 15,
}
print(tips_collect_dictionary(ages))

Output:

{25: ['Owen', 'Jhon'], 15: ['Pepe']}
