Re-write this Python code that counts down from 5 to 0 in a more efficient way:

import time
seconds = 5
print("Remaining time: " + str(seconds))
seconds = seconds - 1
time.sleep(1)
print("Remaining time: " + str(seconds))
seconds = seconds - 1
time.sleep(1)
print("Remaining time: " + str(seconds))
seconds = seconds - 1
time.sleep(1)
print("Remaining time: " + str(seconds))
seconds = seconds - 1
time.sleep(1)
print("Remaining time: " + str(seconds))
seconds = seconds - 1
time.sleep(1)
print("Remaining time: " + str(seconds))

Certainly! The code can be made more efficient by using a loop to handle the countdown instead of repeating similar lines of code. Here’s a refactored version:

import time

# Countdown from 5 to 0
for seconds in range(5, -1, -1):
    print("Remaining time: " + str(seconds))
    time.sleep(1)

In this version, we use a for loop that iterates from 5 down to 0. The time.sleep(1) function is called after each print statement, reducing redundancy and making the code cleaner and easier to maintain.
