Getting python to run an application when the application needs an input file
Question: 
    import subprocess
    subprocess.call(['C:\\Users\michael\\Desktop\\Test\\pdftotext'])
    

pdftotext is the application that will run if I use this ^ code. This works
fine, however, I'm trying to find a way to run pdftotext that includes the
pdf's file name which pdftotext uses to convert it into a text file.

Note this is NOT a question about pdftotext.

When I use cmd in windows to run this I simply type **pdftotext
_fileName_.pdf** and it converts the pdf file into a text file, no problem.
Now I want to do something equivalent with Python.

I changed it to this, but it doesn't work. I'm told "The system cannot find
the file specified" and I've put pdftotext in the src file along with
filename.pdf

    
    
    import subprocess
    subprocess.call(['C:\\Users\michael\\Desktop\\Test\\pdftotext', 'filename.pdf'])
    


Answer: [subprocess.call](https://docs.python.org/2/library/subprocess.html) takes an
iterable where the first item is the executable and the following are switches
and parameters.

This means you need to change the above to this:

    
    
    import subprocess
    subprocess.call(['C:\\Users\michael\\Desktop\\Test\\pdftotext', 'filename.pdf'])
