将python输出值传递给HTML网页

Question

I am working on a audio sensor which detect the frequency or db if you called it. Now that my python program is able to detect the 'db', but I want to use the output and sent it to my web page HTML.

I am using raspberry pi to do that, and also my web server is being hosted by the raspberry pi as well. So basically, the raspberry pi does 2 things, Host webpage & detect the frequency level.

I do not have any idea how to pass those value to HTML.

The follow code is my Python code that I got from online:

import RPi.GPIO as GPIO, time, os
GPIO.setmode(GPIO.BCM)
GPIO.setwarnings(False)

def RCtime(Pipin):
    measurement = 0
    GPIO.setup(Pipin, GPIO.OUT)
    GPIO.output(Pipin, GPIO.LOW)
    time.sleep(0.1)
    GPIO.setup(Pipin, GPIO.IN)
    while(GPIO.input(Pipin) == GPIO.HIGH):
         measurement = measurement + 1
         frequency = (measurement *3.3)/1024
    return frequency

while True:
     frequency = RCtime(18)
     print 'The frequency reading is ', frequency
     time.sleep(0.2)

From my knowledge, I am making a guess that I maybe able to use the output value from the following statment to pass it to my HTML webpage.
print 'The frequency reading is ', frequency

You have to store your 'db' value into a database (sqlite for example) and then make your webpage read it.
