I am trying to define function to generate a power point presentation by python-pptx.
I have my own power point template and multiple images needed to be embedded into each slide. I used * to allow arbitrary number of arguments to functions.

For example, I have 3 iamges (.png). I want to put each image in different slides, said 3 here.
The code I tried: 

from pptx import Presentation
from pptx.util import Inches

def Create_PPT(oldFileName, newFileName, *img):
    prs = Presentation(oldFileName)
    # Create the slides for images
    for image in *img:
        graph_slide_layout = prs.slide_layouts[9]  # 9 is the customized template I create in my oldfile.
        slide = prs.slides.add_slide(graph_slide_layout)
        title = slide.shapes.title
        title.text = image
        left = Inches(0.7)
        top = Inches(0.75)
        height = Inches(6)
        width = Inches(12)
        pic = slide.shapes.add_picture(image, left, top, width = width, height = height)

    prs.save(newFileName)

Create_PPT('mystyle.pptx', 'new.pptx', 'test1.png', 'test2.png', 'test3.png')

I got the error: 

for image in *img:
             ^
SyntaxError: invalid syntax

Moreover, I think my code is incomplete. To loop through and add the slides, I guess I also need to add more syntax. 

for index, _ in enumerate(prs.slide_layouts):
        slide = prs.slides.add_slide(prs.slide_layouts[index])

However, this is not correct one. Above code just loop through to create different slide layouts. My slide layout is fixed, 9 here.
Therefore, I think what I need is to loop through prs.slides.add_slide(), but not sure about this since I got errors each try.

The output will be 3 slides with image on each and the title of each slide is images' name, test1, test2, and test3.
Any suggestion on this?

img is a list, I presume you just want to iterate through it:

for image in img:
    ...
