[Tutor] question about sys.path and importing

[Dick Moores]

This morning I was sternly warned by Wingware support not to leave my 
module of useful functions in Python25\Lib. So I put it in a 
subfolder in site-packages I named "mine". Importing of or from that 
module, mycalc.py goes well, to my surprise, because of

 >>> import sys
 >>> [x for x in sys.path if "site-packages" in x]
['e:\\Python25\\lib\\site-packages', 
'e:\\Python25\\lib\\site-packages\\win32', 
'e:\\Python25\\lib\\site-packages\\win32\\lib', 
'e:\\Python25\\lib\\site-packages\\Pythonwin', 
'e:\\Python25\\lib\\site-packages\\wx-2.6-msw-unicode']
 >>>

in which "mine" isn't included, even though other folders in site-packages are.

Can someone explain this, please?
