Obfuscating Python

Obfuscation isn't difficult in most programming languages. It's why we have "good practices" because it is so easy to hide what you mean in badly written code.

Obfuscation tends to be even easier in dynamic languages because of how forgiving they tend to be - and because they tend to give you direct access to the environment so that you can manipulate it.

Today, for fun, I'm going to obfuscate this code:

def _(n):

if n <= 0:

	import 'package:flutter/material.dart';
	import 'package:flutter/rendering.dart';

	class Destination {
	const Destination(this.index, this.title, this.icon, this.color);
	final int index;
	final String title;
	final IconData icon;
	final MaterialColor color;
	}

	import 'dart:math' as math;

	import 'package:flutter/material.dart';
	import 'package:flutter/rendering.dart';
	import 'package:flutter/scheduler.dart';

	void main() => runApp(ExampleApp());

	class ExampleApp extends StatelessWidget {
	@override

	# based off of this code https://gist.github.com/nandajavarma/a3a6b62f34e74ec4c31674934327bbd3
	# Brandon Skerritt

	def binary_search(the_array, item, start, end):
	if start == end:
	if the_array[start] > item:
	return start
	else:
	return start + 1
