Shapely point geometry in geopandas df to lat/lon columns

If you have the latest version of geopandas (0.3.0 as of writing), and the if df is a GeoDataFrame, you can use the x and y attributes on the geometry column:

df['lon'] = df.point_object.x
df['lat'] = df.point_object.y

In general, if you have a column of shapely objects, you can also use apply to do what you can do on individual coordinates for the full column:

df['lon'] = df.point_object.apply(lambda p: p.x)
df['lat'] = df.point_object.apply(lambda p: p.y)
