Python: Find the list with maximum and minimum length using lambda
Python Lambda: Exercise-26 with Solution
Write a Python program to find the list with maximum and minimum length using lambda.
Sample Solution:
Python Code :
def max_length_list(input_list):
max_length = max(len(x) for x in input_list )
max_list = max(input_list, key = lambda i: len(i))
return(max_length, max_list)
def min_length_list(input_list):
min_length = min(len(x) for x in input_list )
min_list = min(input_list, key = lambda i: len(i))
return(min_length, min_list)
list1 = [[0], [1, 3], [5, 7], [9, 11], [13, 15, 17]]
print("Original list:")
print(list1)
print("\nList with maximum length of lists:")
print(max_length_list(list1))
print("\nList with minimum length of lists:")
print(min_length_list(list1))
Sample Output:
Original list: [[0], [1, 3], [5, 7], [9, 11], [13, 15, 17]] List with maximum length of lists: (3, [13, 15, 17]) List with minimum length of lists: (1, [0])

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")
