Python 2.7“模块”对象没有属性“ setPenRadius”

Question

I am trying to run Princeton University's htree.py which imports stddraw.py . Although I have both files saved locally in the same file, I getting an error saying that 'module' object has no attribute 'setPenRadius' although it is clearly defined in the stddraw file. Any help on what I am doing wrong here would be greatly appreciated.

stddraw v0.2
Traceback (most recent call last):
  File "htree.py", line 42, in <module>
    main()
  File "htree.py", line 37, in main
    stddraw.setPenRadius(0.0)
AttributeError: 'module' object has no attribute 'setPenRadius'

Answer 1

I think that you have a different module with the same name in your path that is being loaded instead of the stddraw.py that you linked to. Try redownloading the stddraw.py module that you want and rename it to something else, eg stddrawprinceton.py . To use the module with the new name, change the import statement in htree.py to:

import stddrawprinceton as stddraw
