66.1.6. Print each line of a file in reverse order. 00:57
Write a program to print each line of a file in reverse order.
Note: take the input file name from the use
Solution
Here is a simple Python program that reads a file and prints each line in reverse order:
# Open the file
filename = input("Enter the file name: ")
with open(filename, 'r') as file:
# Read the lines into a list
lines = file.readlines()
# Loop through the list in reverse order
for line in reversed(lines):
# Print each line
print(line.strip()[::-1])
Here's how it works:
- The
input()function is used to take the file name from the user. - The
open()function is used to open the file. The 'r' argument means the file is opened for reading. - The
readlines()method is used to read all the lines of the file into a list. - The
reversed()function is used to loop through the list in reverse order. - The
strip()method is used to remove any leading or trailing whitespace from each line. - The
[::-1]slice is used to reverse the order of the characters in each line. - The
print()function is used to print each reversed line.
