Avoiding Newline Characters with .readlines()
When reading text files with .readlines(), you may encounter an issue where the returned list includes a newline character (n) at the end of each line. This can be problematic when you don't need or want the newline characters.
Problem:
You have a .txt file with values listed one per line, and you want to store these values in a list. However, when you use .readlines() to read the file, the values in the list have trailing newline characters (n).
Solution:
To remove the newline characters, you can use the following approach:
<code class="python">with open(filename) as f: mylist = f.read().splitlines()</code>
This approach involves opening the file, reading its contents into a string using .read(), and then splitting the string into a list of lines using .splitlines(). .splitlines() automatically removes the newline characters from the lines.
By using this method, you can create a list that contains the values from the text file, without any unwanted newline characters.
