To call something in Python you use parens
- eg. to call f you use f()

So the error is talking about whatever has
parens after it. In this case that's len()
And it's saying len is a string.
That means somewhere in your code you have
created a variable called len and assigned
a string to it. You thus hide the built
in function len()

You need to delete the len variable.
