    HTML in Python

    I would like to create a column to show the average of two columns, y[12] and y[13] from a txt file I tried it like below
    Code:
    f = open(’weather.txt’, ’r’)
g = open(’weather.html’, ’w’)
l = f.readlines()
g.write("<html>\n<head>\n<title>Weather by city</title>\n</head>\n")
g.write("<body>\n<table border=’2’><tr><th>City</th>"+
"<th>Average.</th></tr>\n")
for x in l:
y = x.split(",")
if len(y) > 13:
g.write("<tr><td>" + y[1] + "</td><td>" +(sum( y[12] , y[13])/2) +
"</td></tr>\n")
g.close()
f.close()
    It doesn't work though

      It would, in general, be more helpful to give specific error messages and details that "it doesn't work though". Especially since you're not giving weather.txt or even a few rows of weather.txt. Help us to help you!

      But in this particular case it's likely to be that y[12] and y[13] are both strings, rather than numbers. So change line 10 to:

      Code:
      g.write("<tr><td>" + y[1] + "</td><td>" +str(float( y[12])+float(y[13])/2) +"</td></tr>\n")
      This will probably be a bit ugly, so you could try this instead:
      Code:
      g.write("<tr><td>" + y[1] + "</td><td>%.2f</td></tr>\n"%(float( y[12])+float(y[13])/2))
