[Python-modules-team] Bug#939268: First example in the tutorial doesn't work

[Steve McIntyre]

Package: python3-cairo-doc
Version: 1.16.2-1
Severity: normal

Hi!

I'm looking at using the python3-cairo library in my code as part of a
python3 upgrade. So I've just installed python3-cairo and
python3-cairo-doc to start working with it. Unfortunately, the very
first example given in the tutorial
(/usr/share/doc/python3-cairo-doc/html/tutorial.html) doesn't work:

$ ./cairo.py
Traceback (most recent call last):
  File "./cairo.py", line 4, in <module>
    import cairo
  File "/home/steve/linaro/vlan/vland.git/Vland/visualisation/cairo.py", line 8, in <module>
    surface = cairo.ImageSurface (cairo.FORMAT_ARGB32, WIDTH, HEIGHT)
AttributeError: 'module' object has no attribute 'ImageSurface'

This is not a helpful start!
