Lambda function in Python is ananonymousor also known asunknownfunction meaning that the function does not have a name. They reduce down the code size and makes it easy for the programmer to do faster software development. The syntax for defining lambda function is, lambdaarguments: expression C...
In Python, a`Callable` is a type hint that indicates an object is "callable," meaning it can be called like a function. This includes functions, methods, classes, and any objects that implement the special `__call__` method. When you see `Callable` in a type hint, it often includes...
Key functions in Python are higher-order functions that take a parameter key as a named argument. key receives a function that can be a lambda. This function directly influences the algorithm driven by the key function itself. Here are some key functions: sort(): list method sorted(), min...
Anonymous: Lambda functions are anonymous, meaning they do not have a name. This makes them ideal for short, one-off tasks. Inline: Lambda functions can be defined inline, meaning they can be defined within the same line of code as the function call. This makes them even more concise and...
A Python lambda function is a small anonymous function, an anonymous meaning function without a name. The Lambda functions are mainly used in combination with the functions filter(), map(), and reduce(). This function can take any number of arguments, but can only have one expression and th...
How do I pass a lambda function as an argument to another function? You can pass a lambda function as an argument to another function in the same way you pass any other function. Lambda functions are first-class citizens in Python, meaning you can treat them like any other object, includi...

AWS Lambda is the leading product when it comes to Serverless computing, or Function as a Service (FaaS). With AWS Lambda, computing infrastructure is entirely managed by AWS, meaning developers can write code and immediately upload and run it in the cloud, without launching EC2 instances or ...
The amount you pay is calculated based on the length of time your Lambda function ran for (rounded up to the nearest millisecond), and the amount of memory you allocated to the function. Keep in mind, it’s the amount of memory allocated, not the amount used during an invocation that ...
We fire one warming request, your own function would call itself and so on. All requests would be synchronous, meaning the first one would only terminate after all others have replied. These would be safer approaches, but also more expensive. For now, we thought it would be enough to just...
