This exercise comes from
Want to write this “ Word memory system ”, It's because I see someone who wants to use “ network ” Code to ( Click on the blue text to view the code ) Make a... For the child “ Word memory ” Program . Read that code carefully , It doesn't feel like what I want , Decide to give yourself “ Agitate ” One “ real ” Of “ Word memory system ”, At least let the word library be saved in a disk file , Can be considered as barely usable “ System ”.
“ frame ” concept
I'm studying now python class and python My bag 、 Modular import , Just doing this “ Word memory system ” Time refining .
Although the code is a bit ugly , But it passed the debugging after all , To achieve an end .🤪🤪
System directory structure

Menu selection error prompt
1. Input error 
2. Out of range 
To optimize the “ Menu selection ” Error message String printing format ：
1. Code

from mypytools.python_color import color
menu_str = ' Word practice , Word test , Add new words , System documentation '.split(',') # System menu string list .
while True:
