Question

I got this error when run test.py

C:\Python32>python.exe test.py
Traceback (most recent call last):
  File "test.py", line 5, in <module>
    import httplib
ImportError: No module named httplib

How to correct it?

Code block for test.py:

    else:

You are running Python 2 code on Python 3. In Python 3, the module has been renamed to http.client.

You could try to run the 2to3 tool on your code, and try to have it translated automatically. References to httplib will automatically be rewritten to use http.client instead.
