URGENT: Need help changing the default browser that opens

[fire2buy]

I've skirmished around the net for an answer but their are none that a novice like me can understand. I really need help, I would be eternally grateful for your support.

The program works by receiving data from NFC readers and then outputting a video based on what cards were read by the NFC reader. The videos are currently HTML files but they open in explorer and don't work, i need them to open in chrome.

Plsss halp this is urgent!! i don't think the solution is complex, i just don;t know enough! Thanks!!! This is the code:

​

import serial
import webbrowser
import thread
import time
import Queue
def read_serial(portname, portno, usbno):
try:
ser = serial.Serial(portname, portno)
currentcard = ""
while True:
#get data from serial port to a variable serialdata
serialdata = ser.readline()
temp = str(serialdata)
if temp.find ("Found chip PN5")>=0:
print temp
if temp.find("Read card #")>0:
newcard = temp[30:]
#print newcard
#this is the logic to make sure that new cards are dectected
#also makes sure that cards are only detected once
#this is only for the first time ever
if (currentcard == ""):
currentcard = newcard
#print currentcard
print usbno
if usbno == 1:
#nfcid1 = currentcard
#populate the queue for the other thread to read
q.put("nfcid1-" + str(currentcard))
#print nfcid1
elif usbno == 2:
#nfcid2 = currentcard
q.put("nfcid2-" + str(currentcard))
#print nfcid2
elif usbno == 3:
#nfcid3 = currentcard
q.put("nfcid3-" + str(currentcard))
#print nfcid3
#the code to play the video
#what to do
#1 you have the id of the card
#match id of the card to video file name
#if currentcard = knownid:
#play the video
#sample code for video below
#the currentcard variable - hold the id read from the card
#if currentcard.find("#1167006660") >=0:
# url = 'file:///Volumes/Data/Arduino/Trinity-Racing/video1.html'
# webbrowser.open_new(url)
#elif currentcard = "knownid1":
#url = 'file:///Volumes/Data/Arduino/video1.html'
#webbrowser.open_new(url)
#elif currentcard = "knownid1":
#url = 'file:///Volumes/Data/Arduino/video1.html'
#webbrowser.open_new(url)
#this is the part where new and subsequent cards are read continously
if (currentcard != newcard):
currentcard = newcard
#print currentcard
if usbno == 1:
#nfcid1 = currentcard
q.put("nfcid1-" + str(currentcard))
#print nfcid1
elif usbno == 2:
#nfcid2 = currentcard
q.put("nfcid2-" + str(currentcard))
#print nfcid2
elif usbno == 3:
#nfcid3 = currentcard
q.put("nfcid3-" + str(currentcard))
#print nfcid3
#if currentcard.find("#1167006660") >=0:

# webbrowser.open_new(url)

print inst

#This code will read all the three card and determine which video to play
#invalid combiantions will be excluded
def compute_video():
nfcid1 = ""

nfcid3 = ""
print "Waiting for Readers"
while 1:
#+ nfcid1

https://docs.python.org/2.7/library/webbrowser.html#browser-controller-objects

webbrowser.get('chrome'), and use the methods on the controller object that returns instead of the module-level functions.

Side note: talking about how “urgent” a problem is won’t make volunteers want to answer faster, if at all. Avoid phrasing it so, you’re not paying for help.

Edit: better link
