Now, I'll be walking through some examples to demonstrate how len can be used. First, let's say that I have a variable named list F, containing a list of some floating point numbers. To find the length of this list, I can call the function len and pass in list F, it would look like this. I'll go ahead and run this cell, as you can see, I got five as the length. Next, let's say that I have a variable named nums containing a tuple of some integers, to find the length of this tuple I can call the function len and pass in nums. It would look like this, as you can see, I got six as the length, then let's say that I have a variable…
