Intermediate Python Tutorial #5 - Lambda Functions
Intermediate Python Tutorial #5 - Lambda Functions
Today's Topic: lambda functions, these are known as anonymous functions as you do not have to define them at the beginning of your program. They operate the same as regular functions but only occupy one line and contain a single expression.
In this set of videos I will be explaining more advanced programming concepts and showing you intermediate-advanced tools that you can use in python. A lot of these tools will help you to solve problems/code more efficiently and will save you a ton of time!

Lambda Chops: Recipes for Simpler, More Expressive Code
Ian Robertson, Application Architect, Myriad Genetics, Inc.
Although the new Streams API has been a great showcase for lambda methods, there are many other ways this new language feature can be used to make friendlier APIs and more-expressive code. Lambdas can be used for several tasks that historically required significant boilerplate, type-unsafe constructs, or both. From new ways to express metadata to enforcing proper resource handling, this session takes a look at a myriad of ways, big and small, that you can use lambdas to improve APIs and streamline your code. It also addresses some of the limitations of lambdas and some techniques for overcoming them. Come to get inspired about ways you can use lambdas to write beautiful and effective code.

AWS SQS to Lambda Tutorial in NodeJS | Step by Step
SQS integration with Lambda functions are a new offering from AWS that solve many of the problems of SNS + Lambda. In this video, I show you exactly how to set up a SQS queue and consume events from a Lambda function. I start out by talking about some of the basic concepts of SQS and Lambda integration. From there, I walk you through the AWS console and show you how to create a SQS queue and a Lambda function. Additionally, I show you which permissions you need add to your Lambda IAM role. Finally, I test the setup by manually pushing messages to the Queue and verify they are being processed in the Lambda function.

Illuminating Lambda Expressions in C++
Richard Thomson gives us an insight into lambda expressions in C++ by showing the equivalent manually written function objects. The presentation proceeds from lambda expressions as originally defined in C++11 and then proceeds through enhancements from C++14, C++17 and finally C++20.

Keynote: Writing good programs in functional languages: who, why, how?
by Perdita Stevens
ABSTRACT
Functional programming languages have a reputation for being difficult, and functional programmers have - forgive me - a reputation for being fearsome. Why? Is there any truth in it? And how - if we wish to - could we change these reputations? My research and my teaching are both motivated by the desire to make it easier to develop good software, and my new book, "How to Write Good Programs: a guide for students" (CUP, 2020), with examples in Haskell, Java and Python, approaches the issue pragmatically. I will talk about barriers to success in functional programming, and how they might be torn down or gone round.

SPEAKER - Perdita Stevens
Professor at University of Edinburgh
Perdita Stevens studied mathematics at King's College, Cambridge, and then at the University of Warwick, writing a PhD in algebra under Professor J. A. Green. She then switched to professional software engineering, working for three years at BT's Glasgow Software and Systems Engineering Centre. Here she became interested in modelling of object oriented design, and in the relationship between mathematics and software engineering. She returned to academia in 1994, taking a post as Research Fellow in the Laboratory for Foundations of Computer Science at Edinburgh. Her research interests have spanned model checking, legacy systems reengineering and games for software design; a common thread is that she likes identifying structure in systems and how it changes. From 2000-2006, she held an EPSRC Advanced Research Fellowship on Supporting Software Design.
Currently, she works on mathematical aspects of software modelling and model-driven development, including foundations of bidirectionality and its potential role in democratising decisions about the behaviour of software. She wrote the first textbook on UML, Using UML, which has been translated into seven languages, and her book How to Write Good Programs was published by CUP in 2020. She has sat on over 50 international programme committees and has over 50 publications. She is on the Editorial Boards of journals including Theoretical Computer Science and Software and Systems Modeling, and has chaired conferences including UML (now MODELS), TACAS, FMOODS and FASE, and the Educators' Symposium at MODELS. She has been instrumental in the development of the bidirectional transformations community, helping organise the first Bidirectional Transformations Dagstuhl and cochairing the Bx 2013 workshop at ETAPS; she was the founding chair of the Bx steering committee. Her 2007 paper Bidirectional model transformations in QVT: Semantic issues and open questions was given the 10-year Most Influential Paper Award at MODELS 2017.
In her teaching, she is particularly interested in helping students to be intrinsically motivated life-long learners.
She is married (to Julian Bradfield) with a teenage son and enjoys music, especially singing.

🌟 "Simplify Your Code: Build an Expense Tracker Using Lambda Functions" 🌟
🔍 Dive into the world of functional programming with FreeCodeCamp's project tutorial, where you'll harness the power of Lambda functions to build a sleek and efficient Expense Tracker. Lambda functions, or anonymous functions, offer a concise way to write small functions in your code, making them perfect for tasks that require straightforward operations without the need for naming.
In this tutorial, you will explore how Lambda functions can significantly streamline your programming by reducing the complexity of the syntax while maintaining the functionality. By building an expense tracker, you will apply these functions to perform calculations, filter data, and manage state changes efficiently, all within a clean and user-friendly interface.
📌 Key Learning Objectives:
1. **Understanding Lambda Functions:** Gain a solid understanding of how and when to use Lambda functions to write more concise and readable code.
2. **Application of Lambda in Real-World Tasks:** Learn to use Lambda functions for various operations such as adding expenses, calculating totals, and filtering through records.

🌟 "Simplify Your Code: Build an Expense Tracker Using Lambda Functions" 🌟
🔍 Dive into the world of functional programming with FreeCodeCamp's project tutorial, where you'll harness the power of Lambda functions to build a sleek and efficient Expense Tracker. Lambda functions, or anonymous functions, offer a concise way to write small functions in your code, making them perfect for tasks that require straightforward operations without the need for naming.
In this tutorial, you will explore how Lambda functions can significantly streamline your programming by reducing the complexity of the syntax while maintaining the functionality. By building an expense tracker, you will apply these functions to perform calculations, filter data, and manage state changes efficiently, all within a clean and user-friendly interface.
📌 Key Learning Objectives:
1. **Understanding Lambda Functions:** Gain a solid understanding of how and when to use Lambda functions to write more concise and readable code.
2. **Application of Lambda in Real-World Tasks:** Learn to use Lambda functions for various operations such as adding expenses, calculating totals, and filtering through records.
