In Python, blocks of code, such as the body of a function or loop, can be indicated using indentation. Although, Indentation in blocks or functions is used to group them and to identify the block of code that is
Conventionally, function dispatching is related to the type of the argument. That is, function dispatching is a mechanism for doing different things, depending on whether you pass in an int or a str or a list or whatever. Python is dynamically typed, so you don't have to specify that a ...
You create a file called setup.py in your package's root directory. The setup.py file includes a lot of metadata information such as author, license, maintainers, and other information regarding the package. This is in addition to the packages item, which uses the find_packages() function ...
We'll conclude by talking about some lower-level issues such as register allocation, activation frames, function calls, linkers, and other matters. It's important to note that a major goal of the course is to build a stronger intuition for how all of the parts of a compiler actually work...

Python Tricks: How to Write “Debuggable” Decorators When you use a decorator, really what you’re doing is replacing one funciton with another. One downside of this process is that it “hides” some of the metadata attached to the original(undecorated) function. ...
The function should return a datetime.date or datetime.datetime object (I'll leave it up to you, but am happy to give some input if needed) Why? This is a fun function to have 😄 How? I can give some implementation guidance if needed. Otherwise, you got this!f...

The basic strategy is to replace interpret(registers, code) with a function compile(code) that returns a pointer to a function whose signature is this: void compiled(registers*). The memory for the function needs to be allocated using mmap so we can set permission for the processor to execut...
