If you're strictly defining the function yourself and it's a relatively short definition, a solution without dependencies would be to define the function in a string and assign the eval() of the expression to your function.

E.g.

funcstring = 'lambda x: x> 5'
func = eval(funcstring)

then optionally to attach the original code to the function:

func.source = funcstring
