> Lambdas in Python are awkward

Can you elaborate on that, please?

Considering the examples given by the author, I think they would be a better option.

Not the OP but I think he was referring to the restrictions python puts on lambda expressions:

- they can only contain a single expression

- they cannot contain statements

[Sohcahtoa82]

Python has lambdas that have multiple expressions and statements.

They're called functions.

Python functions aren't anonymous

For precondition checking, shouldn’t that suffice?

Depends on the precondition.
