Python-pptx: How to update chart data for the second chart, if two chart are present on same slide

I want to update chart data for my existing powerpoint presentation slide, having 2 charts, namely a Bar Chart and a Pie Chart. I am successfully able to update the bar chart as it was first element on my content slide placeholder. Now I am not sure how to update the second chart i.e Pie chart on same slide. My code is like as below:

prs = Presentation("Request_Slide.pptx")
slide = prs.slides[0]
for shape in slide.placeholders:
     print('%d %s' %(shape.placeholder_format.idx, shape.name))

with above I got below response:

0 Title 1
1 Content Placeholder 5

With help of this i managed to navigate to my first chart on Slide[0] and updated its chart data however i am struggling to navigate to second chart present in content placeholder. Any suggestions would be of great help and thanks in advance.

Managed to resolve using listing the shape name index and using shape index to update chart data by using below code:

 list_shape_names = [shape.name for shape in slide.shapes]

    if shape_name not in list_shape_names:
        shape_index = None
    else:
        shape_index = list_shape_names.index(shape_name)

But do take care while passing shape_name as it will be case sensitive.
