<tutorial>
Offline processing example of using 51Degrees device detection. The example
shows how to:
<ol>
<li>Import settings from the 51Degrees settings file
<p><pre class="prettyprint lang-py">
dataFile = settings.V3_WRAPPER_DATABASE
properties = settings.PROPERTIES
cacheSize = settings.CACHE_SIZE
poolSize = settings.POOL_SIZE
</pre></p>
<li>Instantiate the 51Degrees device detection provider with these
properties
<p><pre class="prettyprint lang-py">
provider = fiftyone_degrees_mobile_detector_v3_wrapper.Provider(dataFile,
	properties,
	cacheSize,
	poolSize)
</pre></p>
<li>Open an input file with a list of User-Agents, and an output file,
<p><pre class="prettyprint lang-py">
fin = open(inputFile, 'r')
fout = open(outputFile, 'w')
</pre></p>
<li>Write a header to the output file with the property names in '|'
separated CSV format ('|' separated because some User-Agents contain
commas)
<p><pre class="prettyprint lang-py">
fout.write('User-Agent')
for name in properties.split(','):
	fout.write('|' + name)
fout.write('\n')
</pre></p>
<li>For the first 20 User-Agents in the input file, perform a match then
write the User-Agent along with the values for chosen properties to
the CSV.
<p><pre class="prettyprint lang-py">
while i < 20 :
	userAgent = fin.readline().rstrip('\n')
	fout.write(userAgent)
	device = provider.getMatch(userAgent)
	for name in properties.split(','):
		value = device.getValue(name)
		fout.write('|' + value)
	fout.write('\n')
	i = i + 1
</pre></p>
</ol>
This example can be run in any directory, but assumes your
settings file contains a valid dataFile location and has the
IsMobile property selected.
