Is there a way to code:
def fn():
return None
as a lambda, in Python?

A lambda function is a small anonymous function. A lambda function can take any number of arguments, but can only have one expression.
The whole lambda function lambda x : x * x is assigned to a variable square in order to call it like a named function. The variable name becomes the function name so that We can call it as a regular function, as shown below. The expression does not need to always return a value.
In Python, an anonymous function is a function that is defined without a name. While normal functions are defined using the def keyword in Python, anonymous functions are defined using the lambda keyword. Hence, anonymous functions are also called lambda functions.
Yes, the argument list can be omitted:
fn = lambda: None
The production from 5.12. Lambdas is:
lambda_form ::= "lambda" [parameter_list]: expression
The square brackets around parameter_list indicate an optional element.

You have to do this:
fn = lambda: None
