The output shows that all trailing whitespace characters have been removed: hello world Here’s an example of a string with the mixed trailing whitespace sequence '\n\n\n \t \n ': my_string = 'hello world\n\n\n \t \n ' You can then assign this new string to your original variable. It automatically creates a new string without trailing whitespaces. To remove all trailing whitespaces, not only newline characters '\n', you can use the str.rstrip() method without any argument. Problem: Remove all trailing whitespaces from a string-newline '\n', tabular characters '\t', and empty spaces ' '.

The following video gives a short intro to the string.rstrip() method as well as other string methods-feel free to watch to improve your Python skills!īut what if you don’t want to remove only a single trailing newline character '\n' but multiple ones (e.g., '\n\n\n')? Here’s the output-first the original string with the trailing newline (highlighted in the code) and second the new one without it: hello world This is a simple example where we print the string with and without trailing whitespace characters: my_string = 'hello world\n' If you pass a string character argument str.strip(char), it removes the trailing character passed as an argument. The str.strip() method trims whitespaces on the right and returns a new string.
You can solve this problem by using the right-strip method str.rstrip() as you’ve already seen at the beginning of this article. Problem: Remove a single newline character '\n' from the string. Let’s have a look at the alternatives in more detail next! Method 1: Remove Single Trailing Newline Character From String with rstrip() If you want to remove all trailing whitespaces, use the str.rstrip() method without an argument like so: > my_string = 'hello world\n \n\n \t \n\n\n' This actually removes all trailing newline characters: > my_string = 'hello world\n\n\n\n\n\n' Here’s an example: > my_string = 'hello world\n' If you need the string stored in the original variable, simply assign the result to the original variable. Given a string s, create a new one without trailing newline character by calling s.rstrip('\n'). Use str.rstrip() to remove a trailing newline.
