In their defense, some other languages make the length of a string an attribute/property on a string instance. Python feels like the odd one out here making it a free function you must pass an instance to.

If the tech lead spent a lot of time working with another language that made the length an attribute, I think it would be reasonable for them to need to look it up often.
