# These are lines between buses, where on a map, there is only a
# single line, while the entsoegridkit model contains multiple
# lines. We think they are artifacts from either the vt-geojson logics
# or the gridkit algorithms! They are removed from the model!
# def findall(lid):
#    line = lines.loc[str(lid)]
#    return (lines.bus0 == line.bus0) & (lines.bus1 == line.bus1)
# line_dups = pd.read_csv('line-dups.csv', dtype='str', skiprows=11)['line_id']
# pd.set_option('max_rows', 200)
# pd.concat({x: lines.loc[findall(x)] for x in line_dups}).sort_index(level=0)
# is quite a helpful view for comparing their characteristics.
