如何在 python 列表中的每个 URL 的开头/结尾添加引号？

Question

Simple inquiry here that I can't seem to figure out. I've written a line of code to add commas to the end of a list of several hundred URLs as so:

with open('bdall.txt') as f:
    lines = f.read().splitlines()
    new_line = ', '.join(lines)

But how do I modify this (or write new code) to also put all of the URLs from that text file into quotes so that I can paste them all into a program I am writing?

The output of the above is:

http://www.metrolyrics.com/til-i-fell-in-love-with-you-lyrics-bob-dylan.html,
http://www.metrolyrics.com/i-heard-that-lonesome-whistle-lyrics-bob-dylan.html,
etc.

But I need

"http://www.metrolyrics.com/til-i-fell-in-love-with-you-lyrics-bob-dylan.html", "http://www.metrolyrics.com/i-heard-that-lonesome-whistle-lyrics-bob-dylan.html",
etc.

Answer 1

Instead of directly passing "lines" as parameter for the ".join()" method, you can turn it into a list comprehension where you just need to format each line like this:

with open('bdall.txt') as f:
    lines = f.read().splitlines()
    new_line = ', '.join([f'"{line}"' for line in lines])

With this solution, the possibilities are endless. I hope that was helpful
