The example shows how to:
  1. Import settings from the 51Degrees settings file

    dataFile = settings.V3_WRAPPER_DATABASE
    properties = settings.PROPERTIES
    cacheSize = settings.CACHE_SIZE
    poolSize = settings.POOL_SIZE
    

  2. Instantiate the 51Degrees device detection provider with these properties

    provider = fiftyone_degrees_mobile_detector_v3_wrapper.Provider(dataFile,
    	properties,
    	cacheSize,
    	poolSize)
    

  3. Open an input file with a list of User-Agents, and an output file,

    fin = open(inputFile, 'r')
    fout = open(outputFile, 'w')
    

  4. Write a header to the output file with the property names in '|' separated CSV format ('|' separated because some User-Agents contain commas)

    fout.write('User-Agent')
    for name in properties.split(','):
    	fout.write('|' + name)
    fout.write('\n')
    

  5. 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.

    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
    

This example can be run in any directory, but assumes your settings file contains a valid dataFile location and has the IsMobile property selected.
