$ pip --upgrade geocoder
2. get latitude(緯度) and longitude(經度) from current IP
pi@raspberrypi:~ $ python

>>> import geocoder
>>> g = geocoder.ip('me')
>>> g.latlng
[23.5, 121.0]
>>> exit()
-----------------------------------------------------------------------------------------------
B. Measuring Distance
1. install geopy (for both python2 and python3)
$ sudo pip install geopy
$ sudo pip install python-geoip-python3
2. Measuring Distance (Using great-circle distance)
pi@raspberrypi:~ $ python3

>>> from geopy.distance import great_circle
>>> newport_ri = (41.49008, -71.312796)
>>> cleveland_oh = (41.499498, -81.695391)
>>> print(great_circle(newport_ri, cleveland_oh).meters)
864456.7616296598
>>> exit()
-----------------------------------------------------------------------------------------------
C. Looks up the IP information (test for python2 only)
1. install geoip
$ sudo pip install python-geoip
$ sudo pip install python-geoip-python3
$ sudo pip install python-geoip-geolite2
2. Looks up the IP information (real IP)
