打开Excel文件以从python中的相对文件路径运行宏

Question

I am running a code as below in python to open an excel and run a macro. Basically my python script is sitting in

C:\Users\adrlee\Desktop\Python files\Automation

and my excel VBA file (Automation.xlsb) is sitting in

C:\Users\adrlee\Desktop\Python files\Automation\Powerpoint

I am running this code

fileDir = os.path.dirname(os.path.realpath('__file__'));

filename = os.path.join(fileDir, '../Powerpoint/Automation.xlsb')
filename = os.path.abspath(os.path.realpath(filename))
print(filename);

if os.path.exists("Powerpoint/Automation.xlsb"):
    xl=win32com.client.Dispatch("Excel.Application")
    xl.Workbooks.Open(filename)
    xl.Application.Quit() # Comment this out if your excel script closes
    del xl

print("Powerpoint generated");

but i am getting error

pywintypes.com_error: (-2147352567, 'Exception occurred.', (0, 'Microsoft Excel', "Sorry, we couldn't find C:\\Users\\adrlee\\Desktop\\Python files\\Powerpoint\\Automation.xlsb. Is it possible it was moved, renamed or deleted?", 'xlmain11.chm', 0, -2146827284), None)

What am i doing wrong

Answer 1

Thanks for the comments and hints guys! I managed to finally get it right:

fileDir = os.path.dirname(os.path.realpath('__file__'));

filename = os.path.join(fileDir, './Powerpoint/Funnel Automation.xlsb')
print(filename);


xl=win32com.client.Dispatch('Excel.Application')
xl.Workbooks.Open(Filename = filename)
del xl

print("Powerpoint generated");

Answer 2

If fileDir contains

C:\Users\adrlee\Desktop\Python files\Automation\

then joining ..\\Powerpoint\\Automation.xlsb to it will give

C:\Users\adrlee\Desktop\Python files\Automation\..\Powerpoint\Automation.xlsb

which is equivalent to

C:\Users\adrlee\Desktop\Python files\Powerpoint\Automation.xlsb

because .. is equivalent to the parent directory, and the parent directory of ...\\Python files\\Automation is ...\\Python files .

Your question states that the Excel file is actually

C:\Users\adrlee\Desktop\Python files\Automation\Powerpoint\Automation.xlsb

so you should really be joining .\\Powerpoint\\Automation.xlsb to the fileDir variable. (While .. refers to the parent directory, . refers to the existing directory.)

ie use:

filename = os.path.join(fileDir, './Powerpoint/Automation.xlsb')
