dhp 0.0.15

A collection of handy modules, almost guaranteed to get you into trouble.

dhp is a library of snippets almost guaranteed to get you into trouble.

I obtained it from a vendor, on the corner, outside of PyCon.

Actually, this is a growing repository of routines that I find helpful from time to time. I think you might too.

Example Phrasebook Contents

See the Full Documentation for a complete listing.

dhp.doq

• DOQ Data Object Query mapper. Query simple data sources with an ORM like style.

from dhp.doq import DOQ

doq = DOQ(data_objects=data_source)
for rec in doq.filter(occupation='Publisher'):
  print(rec)

dhp.structures

• DictDot - subclasses Python’s built-in dict object and offers attribute access to the dictionary.

from dhp.structures import DictDot

my_dict = {'hovercraft': 'eels', 'speed': 42}
dicdot = DictDot(my_dict)
assert dicdot.hovercraft == 'eels'
assert dicdot.speed == 42

dhp.test

• tempfile_containing - generate a temporary file that contains indicated contents and returns the filename for use. When finished the tempfile is removed.

from dhp.test import tempfile_containing

contents = 'I will not buy this record, it is scratched.'
with tempfile_containing(contents) as fname:
    do_something(fname)

dhp.xml

• xml_to_dict - parse any ugly xml to a python dictionary.

from dhp.xml import xml_to_dict

xml = '<vehicle type="Hovercraft"><filled/><cargo>eels</cargo></vehicle>'
xml_to_dict(xml)

{'vehicle': {'@type':'Hovercraft',
             'cargo':'eels',
             'filled': None}
}
