	Is most commonly used when passing a simple function as an argument to another function. The syntax consists of the <code>lambda</code> keyword followed by a list of <code>arguments</code>, a <code>colon</code>, and the <code>expression</code> to evaluate and return.		Is most commonly used when passing a simple function as an argument to another function. The syntax consists of the <code>lambda</code> keyword followed by a list of <code>arguments</code>, a <code>colon</code>, and the <code>expression</code> to evaluate and return. Can only do things that require a single expression (a single line of code).
