Extract files from MODIS HDF files: Processing in a loop

[ZiaAhmed]

I am trying to extract a file (0=NDVI raster)  from  a MODIS-hdf file and save it as geo-tiff file and project it. I did this in ArcGIS/ModelBuilder with a limted number of files. Below is my phython code for this model. I want to run this code in a loop- that can help to  process (extraction, projection and save in a different directory) all HDF file in the working directory.  I have no experience in python  doing something in a loop. If someone help me to do this in  a loop, that will save  lot of my time.
Thanks
Zia

I solved the with following codes.
Zia

try:
    import arcpy
    arcpy.env.workspace = r"L:/Test_input"
    rasterList = arcpy.ListRasters()

    ##Extract NDVI from HDF
    for raster in rasterList:
        tifOut="L:\\Test_out\\" + raster[9:-22] # SET OUTPUT DIRECTORY WITH FILE NAMES("2000193.h08v05")
        arcpy.ExtractSubDataset_management(raster, tifOut + ".tif", "0")

except:
    print "Extract Subdataset example failed."
    print arcpy.GetMessages()
