How can I ensure the security of f-strings in Python 3?

To ensure the security of f-strings in Python 3, avoid including user input directly in the f-string. Instead, use safe formatting methods.

What are some common vulnerabilities associated with f-strings?

Common vulnerabilities include code injection and exposing sensitive data if user input is not properly sanitized.

Can you give me an example of a secure way to use f-strings?

Sure! Instead of directly embedding user input, you can validate and sanitize it first, then use it in the f-string.

What libraries can help with input validation?

Libraries like Cerberus, Pydantic, and Marshmallow are great for input validation in Python.
