PyZX is ZX Spectrum emulator.
It is written fully in Python programming language. 
Requirements:
------------------
* Python 3.x (python.org)
* PyGame 1.7+ (pygame.org)
Run:
------------------
python3 spectrum.py
Optionally you can try to use -OO optimization flags:
python3 -OO spectrum.py
Keys:
------------------
Ctrl + Alt => switch into special mode
Alt + AnyKey => symbol shift
Ctrl(being in normal mode) + AnyKey => big/small chars
Ctrl(being in special mode) + AnyKey => symbol shift 2
Thanks to Jasper(http://www.spectrum.lovely.net/) for real great Java emulator of
ZX Spectrum. Big amount of code was just automatically translated from Java into
Python, so we need more optimization/rewriting to reach good speed of emulation.
TODO: 
------------------
* Another, real Python approach for the core (Z80 CPU)
* Threads in parallel (video and maybe keyboard)
* TAP/TZX files reading
