Expy is an easy-yet-powerful experiment framework builder for psychology. It's aimed at setting up an experiment without struggling with the manual production of stimuli, data loading and storing, or the other time-consuming works, by using various module functions.
Expy is designed for psycholinguistic experiments, but it's also suitable for any other experiments.
- Various stimuli modules (not need for preparation of massive stimuli pictures).
- Various procedure-controlling modules (instruction, tip, rest-stage, etc.)
- Convenient for stimuli loading and responses recording.
- Getting participants' response data (from keyboard, mouse, or joystick) by one function.
- Sending triggers easily.
- Easy pause or exit from the program.
- Not good at drawing complex shape (e.g., grating) as stimuli (however, you could draw them as loaded pictures).
- Not good at video playing.

# Installation instructions
Expy has been tested on Python3.5 64bit.
(Current it might be unfit for older versions like Python2.7. But since Python2 will become obsolete in the years to come, why not drop it anyaway and take Python3 instead?)
The simplest way to install Expy is through the Python Package Index (PyPI), which ensures that all required dependencies are established. This can be achieved by executing the following command:
pip install expy
sudo pip install expy
# Simple example (An RSPV demo)
from expy import * # Import the needed functions
start() # Initiate the experiment environment
for w in 'ABCDE12345':
drawText(w) # Draw something on the canvas(not the screen)
show(0.2) # Display current canvas on the screen, and keep for 0.2s
