drawnow not found

[Paul Ossenbruggen]

I am new to many of these python packages. I copied a script that looks like this on a Raspberry Pi Model 3B:

import serial

import numpy

import matplotlib

from pylab import *

from drawnow import drawnow

Data = serial.Serial(/dev/ttyACMO',9600)

plot.ion()

while (1)

      if (Data,inWaiting()==0):

          pass

     DataString = Data.readline()

     DataArray = DataString.split(', ')

     t = float(DataArray[0])

     x = float(DataArray[1])

 

     print(t)

Thony stops executing at line 5. No module name 'drawnow'.

I am using python3.

Any help will be appreciated.

After further investigation, I found that I installed numpy and matplotlib using python2. I need python 3 and other apps. More later.

I found why my code was having difficulty. Rookie mistakes. 

Thonny was very helpful. Great tool.
