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

Find current directory and file's directory:

To get the full path to the directory a Python file is contained in, write this in that file:

import os 
dir_path = os.path.dirname(os.path.realpath(__file__))

(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)

To get the current working directory use

import os
cwd = os.getcwd()

Documentation references for the modules, constants and functions used above:

  • The os and os.path modules.
  • The __file__ constant
  • os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")
  • os.path.dirname(path) (returns "the directory name of pathname path")
  • os.getcwd() (returns "a string representing the current working directory")
  • os.chdir(path) ("change the current working directory to path")
