execute a python code from php and take the return value back to the php code example

Question

I have a python script and a PHP script what I need is execute the python script through PHP and should get the return value of python code back to PHP.Here is my codes

I execute this through another php script using a submit button

and here is the python code

def add(a, b):
   # print "ADDING %d + %d" % (a, b)
    return a + b

def subtract(a, b):
   #print "SUBTRACTING %d - %d" % (a, b)
    return a - b

def multiply(a, b):
    #print "MULTIPLYING %d * %d" % (a, b)
    return a * b

def divide(a, b):
   # print "DIVIDING %d / %d" % (a, b)
    return a / b

if __name__ == '__main__':
    divide(10,2)

the result I am getting is

return value is:

there no any value.Please help.Thank you in advance. :)

Finally I found the answer for this problem.In python code I only return the value.But It should be printed too.So here is the modified python code.Hope this will be useful to all of you.

def add(a, b):
   # print "ADDING %d + %d" % (a, b)
    return a + b

def subtract(a, b):
   #print "SUBTRACTING %d - %d" % (a, b)
    return a - b

def multiply(a, b):
    #print "MULTIPLYING %d * %d" % (a, b)
    return a * b

def divide(a, b):
   # print "DIVIDING %d / %d" % (a, b)
    return a / b

if __name__ == '__main__':

   ret= divide(10,2)
   print("ret:",ret)
