# cat d.py
import pyaudio

p = pyaudio.PyAudio()
info = p.get_host_api_info_by_index(0)
numdevices = info.get('deviceCount')
#for each audio device, determine if is an input or an output and add it to the appropriate list and dictionary
for i in range (0,numdevices):
        if p.get_device_info_by_host_api_device_index(0,i).get('maxInputChannels')>0:
                print "Input Device id ", i, " - ", p.get_device_info_by_host_api_device_index(0,i).get('name')

        if p.get_device_info_by_host_api_device_index(0,i).get('maxOutputChannels')>0:
                print "Output Device id ", i, " - ", p.get_device_info_by_host_api_device_index(0,i).get('name')

devinfo = p.get_device_info_by_index(1)
print "Selected device is ",devinfo.get('name')
if p.is_format_supported(44100.0,  # Sample rate
                         input_device=devinfo["index"],
                         input_channels=devinfo['maxInputChannels'],
                         input_format=pyaudio.paInt16):
  print 'Yay!'
p.terminate()

invalid syntax here:
print "Input Device id ", i, " - ", p.get_device_info_by_host_api_device_index(0,i).get('name')

Which version of Python are you using? This is old Python 2 code, it will throw a syntax error on that print statement under Python 3.
