Error " 'dict' object has no attribute 'iteritems' " when trying to use NetworkX's write_shp()

I'm trying to use NetworkX to read a Shapefile and use the function write_shp() to generate the Shapefiles that will contain the nodes and edges (following this example -, but when I try to run the code it gives me the following error:

Traceback (most recent call last): File
"C:/Users/Felipe/PycharmProjects/untitled/", line 4, in
nx.write_shp(redVial, "shapefiles") File "C:\Python34\lib\site-packages\networkx\readwrite\", line
192, in write_shp
for key, data in e[2].iteritems(): AttributeError: 'dict' object has no attribute 'iteritems'

I'm using Python 3.4 and installed NetworkX via pip install.

Before this error it had already given me another one that said "xrange does not exist" or something like that, so I looked it up and just changed 'xrange' to 'range' in the file, which seemed to solve it.

From what I've read it could be related to the Python version (Python2 vs Python3), but I'm not really sure how to proceed now.

I'd really appreciate some guidance. Thanks in advance.

As you are in python3 , use dict.items() instead of dict.iteritems()

iteritems() was removed in python3, so you can't use this method anymore.

Take a look at Python Wiki (Link)

In Built-in Changes part, it is stated that

Removed dict.iteritems(), dict.iterkeys(), and dict.itervalues().

Instead: use dict.items(), dict.keys(), and dict.values() respectively.
