I have installed my python3 this way:
sudo apt-get install make gcc
wget https://www.python.org/ftp/python/3.4.0/Python-3.4.0.tgz
tar xf Python-3.4.0.tgz -C /usr/local/src/
cd /usr/local/src/Python-3.4.0/
./configure –prefix=/usr/local/python3.4
make
make install
ln -s /usr/local/python3.4/bin/python3.4 /usr/bin/python3

when i upload a python file named down.py into the position:
/usr/local/python3.4/lib/python3.4/down.py

why can’t import the module with command:
import /usr/local/python3.4/lib/python3.4/down.py ?
