Answer:
Here is one possible implementation of a program that takes a line of text as input and outputs the line in reverse:
# Get input from the user
line = input("Enter a line of text: ")
# Reverse the line of text using the slicing technique
# with a step of -1 to go through the string backwards
reversedLine = line[::-1]
# Print the reversed line of text
print(reversedLine)
Here is an example of how this program might be used:
Enter a line of text: Hello, world!
