syntactic sugar Unravelling `not` in Python For this next blog post in my series of Python's syntactic sugar, I'm tackling what would seem to be a very simple bit of syntax, but which actually requires diving into multiple layers to fully implement: not. On the surface, the definition of not
syntactic sugar Unravelling `is` and `is not` As part of this blog series on Python's syntactic sugar, I said in the post on unary arithmetic operators that it might be the most boring post in this series. I think I was wrong. 😄 The operators is and is not are very short.
syntactic sugar Unravelling rich comparison operators For the next part of my blog series on pulling apart Python's syntactic sugar, I'm going to be tackling rich comparison operators: ==, !=, >, <, >=, <=. For this post I am going to be picking apart the example of a > b. Looking at
