Python Find Non Printable Characters

What are Non-Printable Characters?

When working with text data in Python, you may encounter non-printable characters that can cause issues with your code. Non-printable characters are characters that are not visible on the screen, such as tabs, newlines, and carriage returns. These characters can be problematic because they can affect the formatting and interpretation of your data.

In this article, we will explore what non-printable characters are and how to find them in Python. We will also provide examples and code snippets to help you handle these characters effectively.

Finding Non-Printable Characters in Python

What are Non-Printable Characters? Non-printable characters are characters that are not visible on the screen. They include characters such as tabs (\t), newlines (\n), and carriage returns (\r). These characters are used to control the formatting of text data, but they can cause issues if not handled properly. For example, if you are reading a text file that contains non-printable characters, you may need to remove or replace them to ensure that your data is formatted correctly.

Finding Non-Printable Characters in Python To find non-printable characters in Python, you can use the `ord()` function, which returns the Unicode code point for a given character. You can also use regular expressions to search for non-printable characters in a string. For example, you can use the `re` module to search for characters that are not printable using the following code: `import re; non_printable_chars = re.findall(r'[^ -~]', 'your_string_here')`. This code will return a list of non-printable characters found in the string.
