[Tutor] Confusion with $PATH

[David Eric]

Very new to python..getting accustomed to files, directories etc
I installed a few versions of python and ended up with a very long PATH
variable, do i need this or can i change it to something shorter?
Doing an online tutorial one exercise was to move a simple program,
helloworld into the PATH so i could run it just by typing it in terminal
window....i moved it into /Library and says file not found..
any advice?
THe following is what comes up for PATH

/Library/Frameworks/Python.framework/Versions/3.1/bin:/Library/Frameworks/Python.framework/Versions/3.0/bin:/Library/Frameworks/Python.framework/Versions/Current/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin
