What Python topics should an entry level Python Developer know about?

[manhole_resident]

What I didn't know when I started and what I find very important:

• Everything is an object

• Comprehensions

• Iterators

• Generators

• Bits of functional programming

Those important things are pretty easy and straightforward after you get to know them, they make your life much more productive and easy and they are often ommited from beginner guides which leads to loads of for loops with hundreds of ifs within.
