Invoking in the terminal

You first have to set the environment settings in your device to access the python 3.

To use, make the script executable and run from the shell:

chmod a+x standalone_python.sh

./standalone_python.sh

or, if that doesn't work (and it may not, depending on filesystem) just:

sh /sdcard/standalone_python.sh

The script at time of writing looks like this:

#! /bin/sh



export EXTERNAL_STORAGE=/mnt/storage

PYTHONPATH=/mnt/storage/com.googlecode.pythonforandroid/extras/python

PYTHONPATH=${
PYTHONPATH
}
:/data/data/com.googlecode.pythonforandroid/files/python/lib/python2.6/lib-dynload

export PYTHONPATH

export TEMP=/mnt/storage/com.googlecode.pythonforandroid/extras/python/tmp

export PYTHON_EGG_CACHE=$TEMP

export PYTHONHOME=/data/data/com.googlecode.pythonforandroid/files/python

export LD_LIBRARY_PATH=/data/data/com.googlecode.pythonforandroid/files/python/lib

/data/data/com.googlecode.pythonforandroid/files/python/bin/python "$@"
