What is Lambda Function?
An anonymous, single-expression function defined inline using the lambda keyword.
Lambda functions are small anonymous functions defined with the lambda keyword: lambda arguments: expression. They can have any number of arguments but only one expression.
Common uses include sorting keys (sorted(data, key=lambda x: x[1])), filtering (filter(lambda x: x > 0, numbers)), and callback functions. For complex logic, named functions are preferred.
