This repository contains tutorials for writing bad Python code. Among other things, you will learn some useless skills and bad habits:
- writing David Beazley style metaprogramming code that only you can understand
- violating PEP 8 and PEP 20
- start writing classes
- and much more!
Here's an example from the brace tutorial:
# beautiful, idiomatic and overall really pythonic utility
# classes, use these everywhere you can
class MutableString(list):
__str__ = lambda self: ''.join(self)
class Stack(list):
push = list.append
class HandyDandyTokenIteratorThingyThing:
...
if token[0] == tokenize.NAME and token[1] in ( 'if', 'elif', 'else', 'while', 'for', 'with', 'try', 'except', 'finally', 'class', 'def' ):
...
funcname = self.do_token()
import keyword
assert funcname[0]==tokenize.NAME and not( keyword.iskeyword(funcname[1]) ), "'%s' is not a valid function name" %( funcname[ 1] )And here's an example of the metaprogramming, taken from the same tutorial. This file can be imported after importing another file that does the magic. You can also import any other modules from files like this and in general do pretty much everything that you can in normal Python files.
# coding=braces
class Thing {
def __init__(self, target) {
self.target = target;
}
def hello(self) {
print("Hello %s!" % self.target);
}
async def async_hello(self) {
print("Hello %s!" % self.target);
}
}This repository is inspired by the work of other mad scientists :)
