Python Exercises, Practice, Solution: Python is a widely used high-level, general-purpose, interpreted, dynamic programming language. Its design philosophy emphasizes code readability, and its syntax allows programmers to express concepts in fewer lines of code than possible in languages such as C or Java.

PDF parser and analyzer
Project description
Fork of PDFMiner using six for Python 2+3 compatibility
PDFMiner is a tool for extracting information from PDF documents.Unlike other PDF-related tools, it focuses entirely on getting and analyzingtext data. PDFMiner allows to obtain the exact location of texts in a page,as well as other information such as fonts or lines.It includes a PDF converter that can transform PDF files into other textformats (such as HTML). It has an extensible PDF parser that can be used forother purposes instead of text analysis.

PDF generation in python using wkhtmltopdf suitable for heroku
Project description
PDF generation in python usingwkhtmltopdf.
Wkhtmltopdf binaries are precompiled and included in the package makingpydf easier to use, in particular this means pydf works on heroku.
Currently using wkhtmltopdf 0.12.4 (with patched qt), requires Python 3.6+.
Install
For python 2 use pip install python-pdf0.30.0.
Async Usage
Generation of lots of documents with wkhtmltopdf can be slow as wkhtmltopdf can only generate one documentper process. To get round this pydf uses python 3’s asyncio create_subprocess_exec to generate multiple pdfsat the same time. Thus the time taken to spin up processes doesn’t slow you down.
See benchmarks/run.pyfor a full example.
Locally generating an entire invoice goes from 0.372s/pdf to 0.035s/pdf with the async model.
Docker
pydf is available as a docker image with a very simple http API for generating pdfs.
Simple POST (or GET with data if possible) you HTML data to /generate.pdf.
Arguments can be passed using http headers; any header starting pdf- or pdf_ willhave that prefix removed, be converted to lower case and passed to wkhtmltopdf.
For example:
In docker compose:
Other services can then generate PDFs by making requests to pdf/generate.pdf. Pretty cool.
API
generate_pdf(source, [**kwargs])
Generate a pdf from either a url or a html string.
After the html and url arguments all other arguments are passed straightto wkhtmltopdf
For details on extra arguments see the output of get_help() andget_extended_help()
![Python Python](https://image.isu.pub/190418145408-8d856445112b384d2f62525cd957583a/jpg/page_1.jpg)
All arguments whether specified or caught with extra_kwargs areconverted to command line args with '--' + original_name.replace('_','-').
Arguments which are True are passed with no value eg. just –quiet,False and None arguments are missed, everything else is passed withstr(value).
Arguments:
- source: html string to generate pdf from or url to get
- quiet: bool
- grayscale: bool
- lowquality: bool
- margin_bottom: string eg. 10mm
- margin_left: string eg. 10mm
- margin_right: string eg. 10mm
- margin_top: string eg. 10mm
- orientation: Portrait or Landscape
- page_height: string eg. 10mm
- page_width: string eg. 10mm
- page_size: string: A4, Letter, etc.
- image_dpi: int default 600
- image_quality: int default 94
- extra_kwargs: any exotic extra options for wkhtmltopdf
Returns string representing pdf
get_version()
Get version of pydf and wkhtmltopdf binary
get_help()
get help string from wkhtmltopdf binary uses -h command line option
get_extended_help()
get extended help string from wkhtmltopdf binary uses -H command lineoption
execute_wk(*args)
Low level function to call wkhtmltopdf, arguments are added towkhtmltopdf binary and passed to subprocess with not processing.
