Removing the last n characters of a string in Python

In this tutorial, we are going to learn about how to remove the last n characters of a string in Python.

consider, we have a following string:

str = "How are you"

Now, we want to remove the last 3 characters you from the above string.

Removing the last n characters

We can remove the last n characters of a string by using the slice notation [ ] with :-n as an argument.

-n is the number of characters we need to remove the from the end of a string.

Here is an example, that removes the last 3 characters from the following string.

str = "How are you"

modified = str[:-3]

print(modified)

Output:

"How are"

Alternatively, we can also use the rstrip() method by passing the last n characters as an argument to it.

str = "How are you"

modified = str.rstrip("you")

print(modified) # "How are"

Another example of rstrip() method:

name = "justin"

modified = name.rstrip("stin") # removing last 4 characters

print(modified) # "ju"
