python - str object is not callable when inserting into SQLite database -


i working on temperature sensor network using onewire temperature sensors runs on raspberry pi 2. following this tutorial , going along, realized setup 1 temperature sensor, whereas setup needs work multiple sensors.

as result of having multiple sensors, need able differentiate sensors 1 another. this, want have 3 columns in sqlite table. encountering error when execute python script supposed log readout sensor, date , time, , sensor name.

here problem, when configuring python script write 3 values table, error.

here code getting error when executing

#!/usr/bin/env python  import sqlite3  import os import time import glob  # global variables speriod=(15*60)-1 dbname='/var/www/templog.db'  # store temperature in database def log_temperature(temp):      conn=sqlite3.connect(dbname)     curs=conn.cursor()     sensor1 = 'sensor1'      curs.execute("insert temps values(datetime('now'), (?,?))" (temp, sensor1))       # commit changes     conn.commit()      conn.close() 

"insert temps values(datetime('now'), (?,?))" (temp, sensor1)

breaking down see creates string , parenthesis appears python function call. nonsensical because have string trying call function. hence error str not being callable, bit cryptic if not experienced python. missing comma:

curs.execute("insert temps values(datetime('now'), (?,?))", (temp, sensor1))

now ? placeholders correctly filled in.

often "str not callable" error result of typos such or duplicated variable names (you think calling function variable contained string), start looking problems when see type of error.

javascript - Function overwritting -

is there way overwrite function or event handling in function? using addeventlistener, can have many event handlers on element want var test=document.getelementbyid("div"); test.addeventlistener("click",function(){alert("im first");},false); test.addeventlistener("click",function(){alert("im second");},false); // alerts "im first" , after "im second" but if want overwrite function/event example based on client width example this function one() { alert("first"); } function two() { alert("second"); } window.onresize = function() { var test = document.getelementbyid("div"); if (window.innerwidth > 500) { test.onclick = 1 } else { test.onclick = two; } } is possible in javascript? in case use effective little known approach. addeventlistener can accept object property handleevent event handler. in case it's easy overwr...
