Sort List of String Numbers Numerically

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

Sample Solution:

Python Code:

# Define a function 'sort_numeric_strings' that sorts a list of numeric strings numerically
def sort_numeric_strings(nums_str):
    # Convert each numeric string to an integer and store the result in 'result'
    result = [int(x) for x in nums_str]
    # Sort the 'result' list in ascending order
    result.sort()
    return result

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

# Print a message indicating the original list
print("Original list:")
# Print the contents of 'nums_str'
print(nums_str)

# Sort the list of numeric strings numerically using the 'sort_numeric_strings' function
print("\nSort the said list of strings (numbers) numerically:")
# Call the 'sort_numeric_strings' function with 'nums_str', then print the result
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]

Flowchart:

Python Code Editor:

Previous: Write a Python program to sort a given mixed list of integers and strings. Numbers must be sorted before strings.
Next: Write a Python program to remove the specific item from a given list of lists.
