Download entire grammar as text.
lambda_form ::= "lambda" [parameter_list]: expression
Lambda forms (lambda expressions) have the same syntactic position as
expressions. They are a shorthand to create anonymous functions; the
expression lambda arguments: expression
yields a function object. The unnamed object behaves like a function
object defined with
def name(arguments):
return expression
See section 7.6 for the syntax of parameter lists. Note that functions created with lambda forms cannot contain statements.
