Creating LineString and length of LineString from multiple latlon points for each row in a Pandas Dataframe

Question

So I want to create a LineString and get the length of the LineString from two sets of LatLon coordinates (points) in each row in a Pandas Dataframe, and store in a new column

Blockquote

How can I do this?

You can use apply to create the output column like this:

import shapely.geometry as geom
your_df['geometry'] = your_df.apply(lambda x: geom.LineString([(x['startlat'], x['startlon']) , (x['endlat'], x['endlon'])]), axis = 1)

If your coordinates columns aren't float make sure to parse them first with float(...)
