How to generate HTML report in Python?

Question

I'm looking for a way to print out all my graphs (from matplotlib but already saved as png files) and some data frames in HTML, just like what I usually do with R2HTML.

However I couldn't find detailed descriptions about Python module or functions doing this. Could anyone give me some suggestions?

Answer 1

Looks like a couple of tools exist. I've focused on simple html text writers since I'll be crafting my report page structures completely from scratch. This may differ from the R2HTML which I would guess has a lot of convenience functionality for the sort of things one wishes to stuff into pages from R objects.

HTMLTags This fella wrote a module from scratch at this ActiveState community page: HTMLTags - generate HTML in Python (Python recipe). In the comments I discovered most of the tools I enumerate for this answer.

htmlgen This package looks pretty good and basic. I'm not sure if its the same module described in this old article.

XIST this one looks pretty legit and includes a parser as well. Here's some sample page generation code using the format that you'll need to use to interject all the appropriate python commands inbetween various html elements. The other format utilizes a bunch of nested function calls which will make the python interjection very awkward at best.

with xsc.build() :
    with xsc.Frag() as myHtmlReport :
        +xml.XML()
        +html.DocTypeXHTML10transitional()
        with html.html() :
            reportTitle = "My report title"

            with html.head() :
                +meta.contenttype()
                +html.title( reportTitle )

            with html.body() :
                # Insert title header
                +html.h1( reportTitle )

                with html.table() :
                    # Header Row
                    with html.tr() :
                        with html.td() : 
                            +xsc.Text( "Col 1 Header" )
                        with html.td() :
                            +xsc.Text( "Col 2 Header" )


                    # Data Rows
                    for i in [ 1, 2, 3, 4, 5 ] :

                        with html.tr() :
                            with html.td() : 
                                +xsc.Text( "data1_" + str(i) )
                            with html.td() :
                                +xsc.Text( "data2_" + str(i) )

# Write the report to disk
with open( "MyReportfileName.html" , "wb" ) as f:
    f.write( myHtmlReport.bytes( encoding="us-ascii" ) )

libxml2 through Python bindings there's a plain vanilla xmlwriter module, which is probably too generic but good to know about nonetheless. Windows binaries for this package can be found here.
