How did Python find 5 in a dictionary containing 5.0? Python does this in constant time without having to scan through every item by using hash functions. When Python looks up a key foo in a dict, it first computes hash(foo) (which runs in constant-time). Since in Python it is requir...

AFAIK Python had exceptions under the spotlight from the beginning – although similarly to Perl it had exception strings before it had exception classes. And in fact it does its best to adhere to its "Errors should never pass silently" philosophy, the few deviations coming to mind having to ...
In addition to that, we will use Python to explore different types of data, including numerical data, time-series data, geospatial data, categorical data, and others. Chapter 2, Visual Aids for EDA, will help us gain proficiency with different tools for visualizing the information that we ...
Why reprex? Getting unstuck is hard. Your first step here is usually to create a reprex, or reproducible example. The goal of a reprex is to package your code, and information about your problem so that others can run it…
While some of the examples you see below may not be WTFs in the truest sense, but they'll reveal some of the interesting parts of Python that you might be unaware of. I find it a nice way to learn the internals of a programming language, and I believe that you'll find it ...
(Sum) Given two lattice subgroups for some , , the sum is equal to the lattice subgroup , where is the matrix formed by concatenating the columns of with the columns of . (Direct sum) Given two lattice subgroups , , the direct sum is equal to the lattice subgroup , where is the bl...
Unicode 6.0 has chosen to use the name "BELL" for the character at U+1F514, which is a symbol that looks like a bell, and is used in Japanese cell phones. This conflicts with the long-standing Perl usage of having "BELL" mean the ASCII "BEL" character, U+0007. In Perl 5.14, "...
