Lambda function as a key function to a sort

Key Takeaways

another instance in which you'll see this Lambda function is as the key function for some kind of sort now in this example here you can see that we have a list and we have a few different tles inside of here now we have a number we have a letter we have a string and it's kind of ambiguous which element we actually want to sort by or how we should sort these various elements now we can specify exactly how to sort that by passing a key function now in this case what the key function will do is simply take any one of our objects here and just strip out the element at index one which in this case is going to be the letter this now is the element that python will sort based on and it's a very common use case for using this Lambda function so if I run this code here you can see now that we're going to sort based on the middle element so the letter so we have a b and c and that's how the sort was applied
