Here\'s a question-based title that captures the essence of the article: How Do I Remove Newline Characters from a List Created with `readlines()` in Python?

readline() Produces Lists with Newline Characters

When using the readlines() method in Python to read the contents of a text file and store them in a list, it includes the newline character (n) at the end of each line. This can be undesirable in certain situations.

Removing Newline Characters

To eliminate the newline characters from the list, you can take advantage of the splitlines() method. splitlines(), as the name suggests, splits the file contents based on newline and returns a list without the trailing n.

Code to Remove Newline Characters

Here is an updated version of your code that demonstrates the use of splitlines():

<code class="python">with open('filename.txt') as f:
    mylist = f.read().splitlines()</code>

Instead of using readlines(), read() reads the entire file as a string. Subsequently, splitlines() splits this string into a list based on line breaks, stripping the newline characters. This approach provides you with a list where each element represents a line from the text file, without the trailing n.
