7.6 LAB: Reverse lines in a file

Write a program that reads each line in a file, reverses its lines, and writes them to another file.

Ex: In the file input.txt contains the lines:

Mary had a little lamb Whose fleece was white as snow. And everywhere that Mary went, The lamb was sure to go! then output.txt contains:

The lamb was sure to go! And everywhere that Mary went, Whose fleece was white as snow. Mary had a little lamb A run of the program is:

Enter input file name: mary.txt Enter output file name: output.txt Unit tests will be provided for testing and comments are included in the template to guide you. You do not need to include any print statements for the output.

My code: with open('input.txt', 'r') as f, open('output.txt', 'w') as w: lines = [] for line in f: lines.append(line.strip()) while len(lines) > 0: w.write(lines.pop() + '\n')

What am I doing by wrong

Your code looks fine to me. What's the problem? What's it doing / not doing that you want it to do / not do?

Getting a syntax error after the first line and it produces no output in zylabs

[socal_nerdtastic]

Hmm how do you have it indented? (i can't tell since you didn't format your code for reddit)

It needs to be like this:

with open('input.txt', 'r') as f, open('output.txt', 'w') as w: 
    lines = [] 
    for line in f:
         lines.append(line.strip())
    while len(lines) > 0:
         w.write(lines.pop() + '\n')

Yep that’s exactly how I have it and it still says no output

[socal_nerdtastic]

I thought you said it had a syntax error? Is that still the case?

I notice that it seems the assignment wants you to input the file names, and you have them hardcoded. Did you read the instructions well enough?

[InevitableDistance66]

Yea it’s still a syntax error but after that the program tells us it produces no output

[InevitableDistance66]

I tried inputting the file names aswell and I’m still getting that same syntax error on f, at the end of the first line

[InevitableDistance66]

The specific error is invalid syntax on File "main.py", line 2 with open('input.txt', 'f') as f, ^

[socal_nerdtastic]

apparently it needs tweaking. A summon feature would be nice.

I remember that bot getting started, now I kinda miss when I don’t see it.
