Python gp.ListFeatureClasses return only one file

[yo]

Hi All,
I m using the gp.ListFeatureClasses to make a list of file in my
directory (containing several hundreds of file)
however when I print the variable in which the List is supposed to be
stored, the print just return one file name....
does any one have an idea????

# Import system modules
import sys, string, os, arcgisscripting, glob, arcpy

# Create the Geoprocessor object
gp = arcgisscripting.create()
# define the workspace
gp.Workspace = r"F:\front\shp_Files\calving_front"
# list the file in the workspace

try:
    shpList = gp.ListFeatureClasses("*.shp")
    shp = shpList.Next()
    print shp

except:
    print arcpy.GetMessages() # allows to get error message when they
happen
