Abbreviations in Python code

When you need to code fast, efforts to type “transaction” look somewhat funny. Why don’t just use abbreviations that will save you from a lot of typing? However, they need to be consistent, so some system of abbreviations is necessary. Such system may look like this:

kw

kwargs

inst

instance

txn

transaction

ctx

context

pth (sometimes is useful)

path

cls

class

fmt

format

mw

middleware

th

thread

dfd

deferred

cb

callback

tmpl

template

fn

filename

dir

directory

ext

extension

app

application

pr

processor (thing that is called middleware in Django)

fs

formset

cmd

command
