# test_pdfwriter.py

from PDFWriter import PDFWriter

with PDFWriter("test_pdfwriter.pdf") as pw:

    pw.setFont("Courier", 12)
    pw.setHeader("Input: test_pdfwriter.py Output: test_pdfwriter.pdf")
    pw.setFooter("Generated by xtopdf: http://bit.ly/xtopdf")

    with open("test_pdfwriter.py") as in_fil:
        for lin in in_fil:
            pw.writeLine(lin)

This recipe shows how to use PDFWriter, a class in the xtopdf tookit (a PDF creation toolkit for Python), with a context manager / with statement.

The advantage of using the with statement with the PDFWriter constructor is that you do not have to remember to call to .close() method of PDFWriter, analogous to how you do not have to call the .close() method of a file object if you use it in a with statement.
