Example some wrong with version 1.0.2 #12

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. install pydot 1.0.2
2. compile the example 

What is the expected output? What do you see instead?
TypeError: cannot concatenate 'str' and 'int' objects

What version of the product are you using? On what operating system?
graphviz 2.18
python 2.5+
pyparsing 1.4.11
pydot 1.0.2
win vista and winxp sp2

Please provide any additional information below.

i find the example at http://dkbza.org/pydot.html like this:

import pydot 
edges=[(1,2), (1,3), (1,4), (3,4)] 
g=pydot.graph_from_edges(edges) 
g.write_jpeg('graph_from_edges_dot.jpg', prog='dot') 

but i get error

i change it like this

edges=[('1','2'), ('1','3'), ('1','4'), ('3','4')]

that is ok.

0.9.10 was using str() to convert the tuple members to strings before 
concatenating
them with node_prefix.

For unknown reasons, 1.0.2 was changed to no longer convert to string.  You can 
only
use strings in the tuples.
