'module'对象没有属性'Serial'

Question

I'm using the following code to communicate my pc with an arduino, but I get the error mentioned in the title, module objet has no attribute Serial.

#!/usr/bin/python

# Importamos la libreira de PySerial
import serial

# Abrimos el puerto del arduino a 9600
PuertoSerie = serial.Serial('/dev/ttyACM0', 9600)
# Creamos un buble sin fin
while True:
  # leemos hasta que encontarmos el final de linea
  sArduino = PuertoSerie.readline()
  # Mostramos el valor leido y eliminamos el salto de linea del final
  print "Valor Arduino: " + sArduino.rstrip('\n')

The curios thing is the the code used to work, but then I installed matplotlib and drawnow libraries, I believe that has caused the problem but I don't know how to fix it, because and need those libraries any way.

The other matter is that is I copy the code line to line into the terminal it works but of course I need I with the loop in a .py file.

Answer 1

The solution is to not name the source file serial.py since in such case Python takes that instead of the actually desired serial module.
