PermissionError [errno 13] when running openpyxl python script in Komodo

Question

I am having trouble using openpyxl scripts in Komodo edit 9 and python 3.4 on Windows 7. I copied some openpyxl code to learn, but it won't execute from Komodo. I receive a permission error 13. I checked my path and python34 is present. The same script will run when I use IDLE or Command Prompt. My Komodo command is currently: %(python3) -u %F Any ideas on what may be causing this issue? The code and error are included below

from openpyxl import Workbook
from openpyxl.compat import range
from openpyxl.cell import get_column_letter

wb = Workbook()

dest_filename = 'empty_book.xlsx'

ws1 = wb.active
ws1.title = "range names"

for row in range(1, 40):
    ws1.append(range(600))

ws2 = wb.create_sheet(title="Pi")

ws2['F5'] = 3.14

ws3 = wb.create_sheet(title="Data")
for row in range(10, 20):
    for col in range(27, 54):
        _ = ws3.cell(column=col, row=row, value="%s" % get_column_letter(col))
print(ws3['AA10'].value)
wb.save(filename = dest_filename)

Answer 1

I faced the same problem yesterday, but because I dumbly let the workbook open while trying to run the script. Closing it fixed the issue.
