0.1.5(2017-11-29)

• Fix some bugs.

0.1.0(2017-11-18)

• Create.

reportgen has the following capabilities, with many more on the roadmap:

• get all the texts in the pptx file
• get all the images in the pptx file
• add one slide simply about charts/tables/images with pandas in a pptx file
• add slides simply about charts/tables/images with pandas in a pptx file

1. Get texts or images in a pptx file.

# import
import reportgen as rpt
# Open a pptx file
p=rpt.Report('analysis.pptx')
# We can get the texts and images simply.
result=p.get_texts()
print('\n'.join(result))
# All the images will saved in folder '.\\images\\'.
p.get_images()

2. Created a analysis report.

#
import reportgen as rpt
      import pandas as pd
      # Open a pptx file
      p=rpt.Report('template.pptx')# The parameters can be defaulted
      # add a cover
      p.add_cover(title='A analysis report powered by reportgen')
      # add a chart slide
      data=pd.DataFrame({'Jack':[90,80,100],'David':[100,70,85]},index=['Math','English','Physics'])
      p.add_slide(data={'data':data,'slide_type':'chart','type':'COLUMN_CLUSTERED'},\
      title='the scores report',summary='Our class got excellent results',footnote='This is a footnote.')
# add a table slide
      data=pd.DataFrame({'Jack':[90,80,100],'David':[100,70,85]},index=['Math','English','Physics'])
      p.add_slide(data={'data':data,'slide_type':'table'},title='the scores report',summary='Our class got excellent results',footnote='This is a footnote.')
      # add a textbox slide
      data='This a paragraph. \n'*4
      p.add_slide(data={'data':data,'slide_type':'textbox'},title='This is a textbox slide',summary='',footnote='')
      # add a picture slide
      data='.\\images\\images.png'
      p.add_slide(data={'data':data,'slide_type':'picture'},title='This is a picture slide')
p.save('analysis report.pptx')

In general, I divide a slide of analysis report into four parts: title、summary、footnote and the body data. And the body are one or more charts/textboxs/tables/pictures.

The add_slide which is the most commonly used function has the following parameters:

add_slide(data=[{'data':,'slide_type':,'type':},],title='',summary='',footnote='',layouts='auto')

For example, we can draw a chart on the left side, and insert a picture on the right.

import reportgen as rpt
import pandas as pd
p=rpt.Report()
scores=pd.DataFrame({'Jack':[90,80,100],'David':[100,70,85]},index=['Math','English','Physics'])
data=[{'data':scores,'slide_type':'chart','type':'COLUMN_CLUSTERED'},\
{'data':'.\\images2.jpg','slide_type':'picture'}]
p.add_slide(data=data)
p.save('add_slide.pptx')

As a lazy person, I also provide a solution with less scripts.

import reportgen as rpt
p=rpt.Report()
imgs=['.\\images\\'+img for img in os.listdir('.\\images\\')]
p.add_slides(data=imgs)
# more functions way
slides_data=[{'title':'ppt{}'.format(i),'data':data} for i in range(10)]
p.add.slides(slides_data)
p.save('add_slides.pptx')

Now you can get a glance at any data.

import pandas as pd
import reportgen as rpt

data=pd.read_excel('Scores.xlsx')
rpt.AnalysisReport(data,filename='Analysis Report of Scores.pptx');

The scripts will make a pptx file which analysis all the fields of the data in a visual way.

• support export analysis report to html
• make the chart_type recommend more intelligence
