Lambad expression

A lambda expression can create a function that can be called, but it returns a function instead of assigning a function to a variable name, so a lambda function is also called an "anonymous function."

The form of a lambda function is:
Lambda arg1, arg2, ... argn:expression using args
That is: Lambda keywords, parameters, colons, expressions

For example:
”’
f = lambda x, y, z:x+y+z
F (2, 3,4)
”’
Two features:
1. A lambda is an expression, not a statement. That is, a lambda expression can appear where a def is syntactically not allowed, such as in the parameters of a list or function call.
2. The lambda body is a single expression, not code fast. That is, the lambda implementation function is simpler and can only be limited logic (if logic is not even implemented in a lambda).
