Python: Sort a given mixed list of integers and strings using lambda

Last update on December 21 2024 07:31:31 (UTC/GMT +8 hours)

Write a Python program to sort a given mixed list of integers and strings using lambda. Numbers must be sorted before strings.

Sample Solution:

Python Code :

# Define a function 'sort_mixed_list' that sorts a mixed list of integers and strings
def sort_mixed_list(mixed_list):
    # Sort the 'mixed_list' using the 'sort' method with a key function
    # The key function first checks if an element is a string (True for string, False for integer) and then sorts accordingly
    mixed_list.sort(key=lambda e: (isinstance(e, str), e))
    
    # Return the sorted mixed list
    return mixed_list

# Create a mixed list containing integers and strings
mixed_list = [19, 'red', 12, 'green', 'blue', 10, 'white', 'green', 1]

# Print the original mixed list
print("Original list:")
print(mixed_list)

# Sort the mixed list using the 'sort_mixed_list' function and print the sorted result
print("\nSort the said mixed list of integers and strings:")
print(sort_mixed_list(mixed_list)) 

Sample Output:

Original list:
[19, 'red', 12, 'green', 'blue', 10, 'white', 'green', 1]

Sort the said  mixed list of integers and strings:
[1, 10, 12, 19, 'blue', 'green', 'green', 'red', 'white']
