This guide shows you how to use the Python str.strip() function.

Prerequisites

Before you begin:

  • Deploy a VPS server. For instance, Ubuntu 24.04.
  • Create a non-root sudo user.
  • Install Python.

The str.strip() Function Syntax

The str.strip() function removes leading and trailing whitespace characters from a string. It does not modify the original string but returns a new string with the whitespace removed.

Here's the basic syntax:

Python
string.strip()

Example:

Python
text = "   Hello, World!   "
stripped_text = text.strip()
print(stripped_text)  # Output: "Hello, World!"

In this example, the str.strip() function removes the leading and trailing whitespace characters from the text.

Practical Use Cases

The str.strip() function is often used in scenarios where user input needs to be cleaned or when processing text data from various sources.

Example:

Python
user_input = "   python  "
cleaned_input = user_input.strip()
if cleaned_input == "python":
    print("Valid input.")
else:
    print("Invalid input.")

In this example, the user's input is cleaned by removing any leading or trailing whitespace before validation.
