Your lambda function can take x as input and x (second letter) can be the output.Remember, this is not to actually return second letter as value, it is only the logic for the sorting function. ['Python', 'list', 'exercises', 'practice', 'solution'] Lambda comes from the Lambda Calculus and refers to anonymous functions in programming.

Original list: It's still nice to be able to imply some type hints and definitely offers more options than only being able to comment regarding expected types of variables. Click me to see the sample solution, 37. In Python, we generally use it as an argument to a higher-order function (a function that takes in other functions as arguments).Lambda functions are used along with built-in functions like filter(), map() etc.. Lambda, filter, reduce and map Lambda Operator Some like it, others hate it and many are afraid of the lambda operator. Let’s check out some exercises that will help understand LambdaÂ better.

Lambda expressions - also known as “anonymous functions” - allow you to create and use a function in a single line. That is trivial: we can literally ask Python whether letter in vowels (assuming letter is some variable - but beware that with vowels being a string, this does a substring search; you should convert vowels to a set first).
