In Ruby you can read from a file using s = File.read (filename). The shortest and clearest I know in Python is with open (filename) as f: s = f.read () Is there any other way to do it that makes it
How do I read every line of a file in Python and store each line as an element in a list? I want to read the file line by line and append each line to the end of the list.
Do you really want to read the entire text into one string variable? Do you really mean with "strip newlines" to replace them with an empty string? This would mean, that the last word of a line and the first word of the next line are joined and not separated. I don't know your use case, but this seems to be a strange requirement.

Python automatically handles universal newlines, thus .split('\n') will split correctly, independently of the newline convention. It would matter if you read the file in binary mode.In that case splitlines() handles universal newlines while split('\n') doesn't.
I am trying to read the lines of a text file into a list or array in python. I just need to be able to individually access any item in the list or array after it is created. The text file is form...
In Python 3 you are allowed to freely mix next(f) and f.readline(), since next() is actually implemented using readline(), and buffering is moved to a separate class used by all mechanisms of reading from a file. Thanks for pointing this out. I now remember reading about it years ago, but it had slipped my mind when I wrote the previous comment.
The shortest, built-in way to achieve opening, reading, and closing a file in Python is using 2 logical lines whether it's condensed down to 1 line or not. So I don't see this answer to be effectively any different from the 3 original answers.
29 text_file.readlines() returns a list of strings containing the lines in the file. If you want only a string, not a list of the lines, use text_file.read() instead. You also have another problem in your code, you are trying to open unknown.txt, but you should be trying to open 'unknown.txt' (a string with the file name).
