python - I use try...except to tell me where has error,but it can't tell me where the error occurred, it will report an error in the upper function

Question

Thank you so much for helping me.
I use try...except to tell me where has error,but it can't tell me where the error occurred, it will report an error in the upper function.
Such as that:
main -> processContent -> processPosition -> setPosition
main:

try:
 SpiderProcess.processContent(results,connect)                      
except Exception as e:
  log.write("process error:" + str(e))
  continue

processContent:

try:
                SpiderProcess.processPosition(result,connect,ID)    
            except Exception as e:
                Log().write("ID:" + ID)
                Log().write("processPosition error:" + str(e))

processPosition:

try:
            Database.setPosition(connect,ID,district,region,community)
            #print("3")
        except Exception as e:
            Log().write("ID:" + ID)
            Log().write("setPosition error:" + str(e))
            return

setPosition:

sql9  = "UPDATE Position SET district = '{0}', region = '{1}' , community = '{2}'   WHERE ID = {7}".format(district,region,community,ID)

At the end, I knew it was "7" error ，but my log file suggested that the error was:

process error:must be str, not int

main -> processContent -> processPosition -> setPosition
I write try...except anywhere. but at the end i need to use print("") to know where has error.
