Python is one of the most approachable languages to learn, thanks to its object-oriented-first approach and its minimal ...

Python objects are “reference counted.” This means that whenever an object is assigned a new name (“a = 4” creates an object “4” and the name “a” is a pointer to the object), or ...

Python grants its users many conveniences, and one of the largest is (nearly) hassle-free memory management. You don’t need to manually allocate, track, and dispose of memory for objects and ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I ...

Python’s implementation of object orientation does have a few quirks. For example, if you create a class variable, it can be read from a subclass without specifying scope like you’d expect.

As pure Python code, it’s slow, because Python must convert back and forth between machine-native numerical types and its own internal object types. Now consider the Cython version of the same ...

Understanding classes in Python. Before diving into metaclasses, it’s essential to have a solid grasp of classes in Python. In Python, a class is a blueprint for creating objects.

Generally, when a Python call hands an object out to a C program, it increments the reference count by one. The C code can then do what it likes with the object without worrying that it will be ...

Python is a versatile, powerful language but sometimes it’s not the best choice, especially if you’re doing work in embedded systems with limited memory. Sometimes you can get away with… ...

You can use these quantum objects in regular arithmetic operations, just like any other Python objects. For example, if you have two Pauli operators, sz and sy, you could create a Hamiltonian, like ...
