and then you can use str.replace to remove the newlines:

3 You can read from a file in one line:
Please note that this does not close the file explicitly. CPython will close the file when it exits as part of the garbage collection. But other python implementations won't. To write portable code, it is better to use

join() will join a list of strings, and rstrip() with no arguments will trim whitespace, including newlines, from the end of strings.

1 You can also strip each line and concatenate into a final string.
This would also work out just fine.

This is a one line, copy-pasteable solution that also closes the file object:

List is faster than generator but heavier on memory. Generators are slower than lists and is lighter for memory like iterating over lines. In case of "".join(), I think both should work well. .join() function should be removed to get list or generator respectively.

Sma MaSma Ma 2,8651 gold badge28 silver badges37 bronze badges I don't feel that anyone addressed the [ ] part of your question. When you read each line into your variable, because there were multiple lines before you replaced the \n with '' you ended up creating a list. If you have a variable of x and print it out just by x or print(x) or str(x) You will see the entire list with the brackets. If you call each element of the (array of sorts) x[0] then it omits the brackets. If you use the str() function you will see just the data and not the '' either. str(x[0]) answered Mar 6, 2015 at 20:16
Maybe you could try this? I use this in my programs.

This code will help you to read the first line and then using the list and split option you can convert the first line word separated by space to be stored in a list. Than you can easily access any word, or even store it in a string. You can also do the same thing with using a for loop. answered Jan 23, 2016 at 10:26

Is the best way to get all the lines of a file, the '\n' are already stripped by the But if nonetheless you want to strip each lines:
