Help with Python -> html

[lukeyd]

Good afternoon

I'm quite new to Python and I am trying to get the result of a script to show into a html tag - so within my app.py I have the following code;

file = open("blocks.txt", "r")
line_count = 0
for line in file:
    if line != "\n":
        line_count += 1
file.close()

print(line_count)

Then within my index.html I put this;

  <b>IP's Blocked: <label>{{line_count}}</label></b>

As you can imagine, this mustn't be right. How can I get it to work ?
