29. Heterogeneous Max Finder Lambda

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

Sample Solution:

Python Code :

# Define a function 'max_val' that takes a list 'list_val' as input
def max_val(list_val):
    # Find the maximum value in 'list_val' based on two criteria:
    # 1. First, sort by whether the element is an integer or not (True for integers, False for non-integers)
    # 2. Second, sort lexicographically by the elements themselves
    max_val = max(list_val, key=lambda i: (isinstance(i, int), i))
    
    # Return the maximum value found in the list
    return max_val

# Create a list 'list_val' containing a mix of strings and integers
list_val = ['Python', 3, 2, 4, 5, 'version']

# Print the original list 'list_val'
print("Original list:")
print(list_val)

# Find and print the maximum values in the list using the 'max_val' function and lambda expressions
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
