"# Introduction\n",
"This notebook mostly features topics that are (IMO) overlooked.\n",
"* environment; there are a lot of choices for where to develop and where to deploy; I'll try to gather and classify as much viable options as I can.\n",
"* typing; not everyone knows about annotations' existence (let alone that of the module); typing greatly enhances programmer's performance in any PL, and python is not an exception to that.\n",
"* data model; python has a very strict and simple data model behind it; once you understand it, things like \"why this attribute returns a totally different thing\" will be more obvious.\n",
"* working with files; there are approaches beyond `open`+`.write`/`.read`.\n",
"* asyncio; the only correct way to do IO, if you don't wish to waste time and memory.\n",
"* obscure new features; `match`, `Self`, `type | type`, etc.; they are important, but not omnipresent as per their (in-language) novelty.\n",
"* styling;\n",
"\n",
"Most sections will eventually include \"prerequisites\" part (things you need to know before looking into this section); things required are mostly found in the official tutorial."
