Description
There is no module named openpyxl.style on the Python3 version of openpyxl. There is, however a openpyxl.styles module in the namespace of openpyxl. But a simply name change update on line 577 of pandas/io/excel.py isn't the quick fix as there are other differences causing errors.
My offending code:
diff_output = diff_panel.apply(report_diff, axis=0)
def has_change(row):
if "--->" in row.to_string():
return "Y"
else:
return "N"
diff_output['has_change'] = diff_output.apply(has_change, axis=1)
-->diff_output[(diff_output.has_change == 'Y')].to_excel('my-diff.xlsx')

It appears to me that there seems to be sufficient differences in openpyxl between Python2 and Python3. Something the pandas devs might want to be aware of.
