| 76 | Lambda forms (lambda expressions) have the same syntactic position as | |
| 77 | expressions. They are a shorthand to create anonymous functions; the | |
| 78 | expression <code>lambda <var>arguments</var>: <var>expression</var></code> | |
| 79 | yields a function object. The unnamed object behaves like a function | |
| 80 | object defined with | |

| 88 | <P> | |
| 89 | See section <A href="function.html#function">7.5</A> for the syntax of parameter lists. Note | |
| 90 | that functions created with lambda forms cannot contain statements. | |
