Python: Sort each sublist of strings in a given list of lists using lambda

Python Lambda: Exercise-27 with Solution

Write a Python program to sort each sublist of strings in a given list of lists using lambda.

Sample Solution:

Python Code :

# Define a function 'sort_sublists' that takes a list of lists 'input_list' as input
def sort_sublists(input_list):
    # Use list comprehension to create a new list 'result'
    # Sort each sublist in 'input_list' based on the first element of each sublist
    # The sorted() function is used with a lambda function as the sorting key
    result = [sorted(x, key=lambda x: x[0]) for x in input_list]
    
    # Return the sorted list of lists
    return result

# Create a list of lists named 'color1'
color1 = [["green", "orange"], ["black", "white"], ["white", "black", "orange"]]

# Print the original list 'color1'
print("\nOriginal list:")
print(color1)

# Sort each sublist of 'color1' using the 'sort_sublists' function and print the result
print("\nAfter sorting each sublist of the said list of lists:")
print(sort_sublists(color1))

Sample Output:

Original list:
[['green', 'orange'], ['black', 'white'], ['white', 'black', 'orange']]

After sorting each sublist of the said list of lists:
[['green', 'orange'], ['black', 'white'], ['black', 'orange', 'white']]
