Above is the script for measuring time for saving data to database using python and inputing from andoid updated. While running the same it is hosting but after saving text it giving error below

This typically means that you attempted to use functionality that needed
an active HTTP request. Consult the documentation on testing for
information about how to avoid this problem.

threading.Thread(group=None, target=None, name=None, args=(), kwargs={})
args is the argument tuple for the target invocation. Defaults to ()
t_args = (1)
assert type(t_args) is tuple, "except tuple, get {0}".format(type(t_args))
>>> AssertionError: except tuple, get <class 'int'>
t_args = (request,)
print type(t_args)
>>> <class 'tuple'>
t= threading.Thread(target=getDataFromAndroid, args=t_args)
tuple args =() / list args =[]
here you can also use partial from functools to call with args
class threading.Timer(interval, function, args=[], kwargs={})
threading.Timer(1, partial(your_method, your_arg_a, your_arg_b)).start()
there is a built-in module called timeit ,
This module provides a simple way to time small bits of Python code. It has both a Command-Line Interface as well as a callable one. It avoids a number of common traps for measuring execution times
import timeit
....
start = timeit.default_timer()
t.start()
t.join()
print timit.default_timer - start
