I'm trying to load and read shapefile via Tkinter and tkFileDialog.

Following code shows what done .

Firstly I try to read shapefile directly and print its content - no error , then reading the same shapefile with Tkinter dialog produce error.

import shapefile

import Tkinter, tkFileDialog



# Read the Arena shapefile using the Reader class of the pyshp module

arenafile = r"dataArenas_NBAArenas_NBA.shp"

arena_shapefile = shapefile.Reader(arenafile)

arena_shapes = arena_shapefile.shapes()

arena_records = arena_shapefile.records()



print arena_records



root = Tkinter.Tk()

root.withdraw()

arenafile_tk = tkFileDialog.askopenfile(parent=root,

                                    mode='rb',

                                    initialdir="dataArenas_NBA",

                                    title="Select Arena Shapefile",

                                    filetypes=(("shapefiles", "*.shp"),    ("all files", "*.*")))

if arenafile_tk != None:

    arena_shapefile_tk = shapefile.Reader(arenafile_tk)

    arena_shapes_tk = arena_shapefile_tk.shapes()

    arena_records_tk = arena_shapefile_tk.records()

    arenafile_tk.close()

    print arena_records_tk

This code produce following output:

Link to Arena shapefile

Short answer: try:

arenafile_tk = tkFileDialog.askopenfilename()

instead of:

arenafile_tk = tkFileDialog.askopenfile()

and adjust the arguments accordingly.

Long answer: A shapefile consists of multiple files, when you open the ".shp" file name, it seeks out the others:

arena_shapefile = shapefile.Reader(r"dataArenas_NBAArenas_NBA.shp")

If you try to pass an open file handle, as returned by askopenfile(), it expects you to provide information about those other files:

arena_shp_file = open(r"dataArenas_NBAArenas_NBA.shp", "rb")

arena_dbf_file = open(r"dataArenas_NBAArenas_NBA.dbf", "rb")

arena_shapefile = shapefile.Reader(shp=arena_shp_file, dbf=arena_dbf_file)

Or some such.
