Minipy

Minipy is a golfing "language" created by Challenger5. It is Python, but with the following statements prepended to every program: import sys as y av = sys.argv if len(av) > 1: v1 = av[1] try: v2 = eval(v1) except SyntaxError: pass import os import re import functools as ft import string as st import copy as cp import random as rd import math as m ri = random.randint rt = lambda seq: seq[ri(0, len(seq)-1)] N = None _i = __import__ _b = __builtins__ _B = dir(_b) ab = abs al = all an = any bn = bin c = chr cx = complex d = dict dr = dir em = enumerate e = eval x = exec b = lambda x: lambda y: eval(x) fm = lambda x,y: map(b(x),y) ff = lambda x,y: filter(b(x),y) fr = ft.reduce fl = float gtat = getattr hsat = hasattr dlat = delattr stat = setattr hx = hex i = input n = lambda *args: eval(input(*args)) sr = "" t = int l = len ls = list ot = oct o = open f = lambda s: o(s).read p = print r = range rp = repr rvr = reversed rnd = round srt = sorted s = str sm = sum v = vars z = zip def rf(s): # regex finder index = s.index("!") regex = re.compile(s[:index]) search = s[index + 1 :] if search[0] == "!": return regex.findall(search[1:]) else: return regex.findall(eval(search)) q = chr(34) k = "\n"

def e(s): raise RuntimeError(s)

This shortens the names of functions, automatically imports modules, and creates some useful functions.

Interpreter
Here is a (minimized) Python interpreter for Minipy. It assumes that the above statements are loaded into the file  stored in the current directory. It executes a file given as a command line argument.

from minipy import*;x(f(v1))

Examples
program:

p("Hello, World!")

Quicksort:

def q(k): if l(k)<2:return k p=rt(k);return q(ff("y>p",k))+q(ff("y<=p",k))

Factorial:

p(m.factorial(v2))
