In this tutorial, we will look at how to remove the last n characters from a string in Python with the help of some examples.
How to remove the last n characters from a string?
Python strings are immutable which means that they cannot be modified. However, you can create a copy of the string with the last n characters removed and assign it to the original string variable.
To remove the last n characters from a string, slice the string from its start to the index of the nth character from the end. Using negative indexing can be helpful here. The following is the syntax –
# remove last n characters from a string s = s[:-n]
It returns a copy of the original string with the last n characters removed.
Let’s look at some examples -.
Remove the last 2 characters from a string
In this case n = 2, hence we slice the string from its starting index (which is 0) to -2 (which represents the index of the 2nd last character in the string).
# create a string s = "THIS IS SPARTAAA" # remove last 2 characters print(s[:-2])
THIS IS SPARTA
You can see that the resulting string does not have the last two characters from the original string.
Remove the last 3 characters from a string
We can similarly use the above syntax to remove the last three characters from a string.
# create a string s = "THIS IS SPARTAAA" # remove last 3 characters print(s[:-3])
THIS IS SPART
The resulting string has the last three characters removed.
