I made a minimalist program to show it:
#!/usr/bin/env python3
from openpyxl import Workbook
with Workbook() as wb_out:
print('In loop')
print('After loop')
This results in:
Traceback (most recent call last):
File "./test.py", line 7, in <module>
with Workbook() as wb_out:
AttributeError: __exit__

That seems to work. I changed it to:
#!/usr/bin/env python3
from contextlib import closing
from datetime import datetime
from openpyxl import Workbook
with closing(Workbook()) as wb_out:
print('In loop')
wb_out.save('testing_' + datetime.now().strftime('%Y-%m-%d') + '.xlsx')
print('After loop')
And I see:
In loop
After loop
And a testing Excel file.
Thanks.
