Python: Sort a given list of strings(numbers) numerically using lambda

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

Write a Python program to sort a given list of strings (numbers) numerically using lambda.

Sample Solution:

Python Code :

# Define a function 'sort_numeric_strings' that sorts a list of strings containing numeric values
def sort_numeric_strings(nums_str):
    # Sort the 'nums_str' list using the 'sorted' function with a key function
    # The key function converts each element to an integer using 'int' and sorts them numerically
    result = sorted(nums_str, key=lambda el: int(el))
    
    # Return the sorted list of numeric strings
    return result

# Create a list of strings 'nums_str' containing numerical strings
nums_str = ['4', '12', '45', '7', '0', '100', '200', '-12', '-500']

# Print the original list of strings 'nums_str'
print("Original list:")
print(nums_str)

# Sort the list of strings numerically using the 'sort_numeric_strings' function and print the sorted result
print("\nSort the said list of strings (numbers) numerically:")
print(sort_numeric_strings(nums_str)) 

Sample Output:

Original list:
['4', '12', '45', '7', '0', '100', '200', '-12', '-500']

Sort the said list of strings(numbers) numerically:
['-500', '-12', '0', '4', '7', '12', '45', '100', '200']
