NameError: name 'select_pour_point' is not defined - python-2.7

Question

I am receiving this error when trying to setup variables for each pour point. It is a
cur_point = select_pour_point(POUR_POINTS, NAME_FIELD, name)
NameError: name 'select_pour_point' is not defined
HELP!
import shedtools as st
# Directories
SCRATCH = "C:\\SCRATCH"
OUT_FOLDER = "C:\\WATERSHEDS"
# inputs
POUR_POINTS = "C:\\Hawaii_DEM\\Hawaii.shp"
FLOW_DIRECTION = "C:\\Hawaii_DEM\\hawaii_flwdir"
STATS_RASTER = "C:\\HawaiiRFGrids_mm\\RF_MM_BI_Ann"
RASTER_NAME = "stats"
NAME_FIELD = "Id"
STATISTICS = "MEAN"
with arcpy.da.SearchCursor(POUR_POINTS, NAME_FIELD) as cursor:
for point in cursor:
name = str(point[0])
print "Working on pour point %s" % (name)
cur_point = select_pour_point(POUR_POINTS, NAME_FIELD, name)
shed_raster = make_watershed_raster(FLOW_DIRECTION, cur_point, name, SCRATCH)
Error I am receiving is:
Traceback (most recent call last):
File "C:\\exercise_5.py", line 30, in <module>
cur_point = select_pour_point(POUR_POINTS, NAME_FIELD, name)
NameError: name 'select_pour_point' is not defined
Line 30 is:
cur_point = select_pour_point(POUR_POINTS, NAME_FIELD, name)

Answer 1

You import your shedtools.py script using import shedtools as st. Therefore, you need to prefix select_pour_point and make_watershed_polygon with st.:
e.g. st.select_pour_point(...)
Not related to your error BUT open your arcpy.da.SearchCursor using with to make sure it is closed again after using.
import shedtools as st
# ...
with arcpy.da.SearchCursor(POUR_POINTS, NAME_FIELD) as cursor:
for point in cursor:
name = str(point[0])
print "Working on pour point %s" % (name)
cur_point = st.select_pour_point(POUR_POINTS, NAME_FIELD, name)
shed_raster = st.make_watershed_raster( \
FLOW_DIRECTION, cur_point, name, SCRATCH)
Alternatively, instead of prefixing your functions with st., you could also import your functions using:
from shedtools import select_pour_point, make_watershed_raster
If you do so, no prefixing is necessary:
from shedtools import select_pour_point, make_watershed_raster
# ...
with arcpy.da.SearchCursor(POUR_POINTS, NAME_FIELD) as cursor:
for point in cursor:
name = str(point[0])
print "Working on pour point %s" % (name)
cur_point = select_pour_point(POUR_POINTS, NAME_FIELD, name)
shed_raster = make_watershed_raster(FLOW_DIRECTION, cur_point, name, SCRATCH)
