     "Sometimes you want to use the same code multiple times, so you could embed this code into a function. However, sometimes the code you want to use is so short that putting it into a function feels a bit over the top. This is where <b>lambda functions</b> are useful. <br><br>Lambda functions are functions that can take any number of arguments but can only have one expression in their function body. To demonstrate, see the code below. Here we have two functions that do exactly the same, but one is a lambda function and the other one is a normal function. "
