in python, how to escape “{” in formatted string like f”{something}”

In Python, you can escape the opening curly brace ‘{‘ in a formatted string by using double curly braces ‘{{‘ to represent a single curly brace. Here’s an example:

something = "Hello"
formatted_string = f"{{{{ {something} }}}}"
print(formatted_string)

Output:

{{ Hello }}

In the above example, {{ represents the escaped opening curly brace, {something} is the placeholder for the variable, and }} represents the closing curly brace.

By doubling the curly braces, Python will interpret it as a literal curly brace and not as a placeholder.
