How To Check End Of Line In Python

In this tutorial, you’ll learn how to check the end of a line in a file using Python. This skill can be useful when parsing and extracting information from structured text files and ensuring that the reading process is accurate.

Step 1: Create a Sample Text File

Create a sample text file called example.txt with the following content:

This is line 1.
This is line 2.
This is line 3.
End of file.

Step 2: Open the Text File in Python

Open the example.txt file in Python using the open() function. The syntax of the open() function is:

For this tutorial, you’ll only need the file and mode parameters. Open the file in read mode (mode='r'). Replace file with the path of your file.

Step 3: Read the File Line by Line

Now, you can read the file line by line using a for loop, as shown below:

Step 4: Check the End of Line Character

You can check whether the current line is the last line by checking the EOL character. Here’s how you can do this:

The output of the script should look like this:

Line: This is line 1. does end with the EOL character.
Line: This is line 2. does end with the EOL character.
Line: This is line 3. does end with the EOL character.
End of file.

Conclusion

In this tutorial, you’ve learned how to check the end of a line in a file using Python. This skill can be useful when parsing and extracting information from structured text files and ensuring that the reading process is accurate.

As you work with different text files, you may need to adjust the EOL character according to the operating system you are using.
