Lambda Functions: Key Characteristics

The characteristics of lambda functions are as follows:

1. Concise: The lambda function is an anonymous function that can be written in one line of code without the need to use the “def” keyword for definition.
2. Brief: lambda functions typically only contain one expression, so the function body is short and does not need to use a return statement to return the result.
3. Inline: Lambda functions are defined within an expression and can be directly used where needed without the need for explicit naming and definition.
4. Simple syntax: lambda functions have a relatively simple syntax, consisting of the keyword lambda, a list of parameters, and directly followed by an expression.
5. Lambda functions can be used in a wide range of scenarios, such as being passed as parameters to higher-order functions, list comprehensions, sorting, and anywhere else a function object is needed.
6. Functional programming: Lambda functions are an important component of functional programming, supporting higher order operations on functions, allowing functions to be passed as parameters, and returning function objects.
7. Simplify code: Lambda functions can streamline code, eliminating the need to define extra functions and reducing complexity and redundancy in the code.
