Error in formula.py in xlwt3 python

Question

I'm trying to write in a xls or xlsx, trying to use the xlwt3 but it gives me the following error message when import:

Traceback (most recent call last):

class Formula(object):
ValueError: '__init__' in __slots__ conflicts with class variable

Is there a solution or any other tool?

Using in MacOS and xlwt3-0.1.2

Answer 1

__init__ should not be listed in the __slots__ attribute of the class; slots cannot refer to methods as each slot is implemented by a descriptor object instead.

There is a pull request in the project repository that fixes that specific problem. It simply removes the "__init__" string from the __slots__ definition.

Do note that the authors of the package have abandoned the project:

DEVELOPMENT STOPPED - 03.01.2011

I doubt that there will ever be a stable version of xlwt3.

Answer 2

I'm trying to write in a xls or xlsx

As an alternative, the XlsxWriter module works with Python 2 and 3.

Answer 3

Try package xlwt-future for writing xls files in Python 3.x
