Python Remove Last Character from String

String manipulation is one of the most commonly used features in python. Different approaches, such as string slicing techniques and indexing, can be used to manipulate a string. We only want to eliminate the last character from a string in rare circumstances.

In Python, the [:-1] slice notation is used to delete the string’s last character. This notation picks up the last character in a list. After that, the syntax returns all the characters except for the last one. This guide will walk you through three examples to help you understand removing the string’s final character through different methods. These example programs will show you how to complete this work in just a few simple steps.

Note: All these illustrations are implemented using Spyder.

The composition for Eliminating the Last Character from String

Here is the composition for erasing the closing character from a string.

# my_str1 = “A new systems”

# print(my_str1[:-1])

Here are some examples of removing the final character from a string using different techniques. We have implemented these examples using the Spyder IDE.

Example 1:

You can delete the final character of the string by accessing its positive index.  We have used a sample string in the following example. We began by calculating the total amount of characters in the string. This is done in order to get to the string’s final character. After that, we have used slicing for the removal of the string’s last character. Finally, we have displayed the output. Hence, you can see that the last character of the string is deleted.

your_string = "corporate organizations"

leng = len(your_string)

delete_last = your_string[:leng-1]

print(delete_last)

Upon execution of the above-cited code, the output will look like this.

Example 2:

You can also delete the string’s last character by accessing its negative index. Refer to the following example.

Here we have used a sample string. You can add any string according to your work dependency. For deleting the last character of the string, indexing begins from -1. We have sliced it from the -1 index to remove the final character. Finally, we have displayed the output. Hence, you can see that the string’s final character is deleted by negative slicing.

your_string = " corporate organizations  "

delete_last = your_string [:-1]

print(delete_last)

Upon execution of the above-cited code, the output will appear like this.

Example 3:

rstrip is a popular string method for deleting characters from the string’s right side. It’s a Python built-in function that returns all of the string’s characters except the last one. As a result, we will use this function to remove the string’s last character. It is a plain and simple method that necessitates one line of code. Here’s an example you can look at to better understand what the method is about and how it works.

In this example, the user will provide input in the form of a string. You can add any string according to your work dependency. After that, we have used the rstrip method to that string for the deletion of the final character. Finally, we have displayed the output. Now you have seen how the final character of the string is removed by the rstrip function. Rstrip is one of the commonly used string functions in python. Write the same code that is displayed underneath, or you can alter it if required.:

your_string = input (" Provide the string: " )

remaining_str = your_string.rstrip(your_string[-1])

print(remaining_str)

The message “Provide the string” is displayed on this screen. The user will next be inquired to enter the information. Once the user has submitted input, the last character of the string will be removed. Upon execution of the above-cited code, the output will appear like this.

Conclusion

This guide has taught us the basic methods to delete the final character from a string. Different methods are explained with proper explanations to help you understand and implement the code easily. Out of all these, positive and negative indexes by slicing are the easiest and commonly used methods. You are free to employ any of these methods mentioned in this guide that you prefer and meet your needs.
