Hi!

I made a typing error, and couldnt edit the post :( this is the code:


#!/usr/bin/env python
from __future__ import division
from subprocess import PIPE, Popen
import psutil
import smtplib

def get_cpu_temperature():
    process = Popen(['vcgencmd', 'measure_temp'], stdout=PIPE)
    output, _error = process.communicate()
    return float(output[output.index('=') + 1:output.rindex("'")])


def main():
    cpu_temperature = get_cpu_temperature()
    cpu_usage = psutil.cpu_percent()

    ram = psutil.phymem_usage()
    ram_total = ram.total / 2**20       # MiB.
    ram_used = ram.used / 2**20
    ram_free = ram.free / 2**20
    ram_percent_used = ram.percent

    disk = psutil.disk_usage('/')
    disk_total = disk.total / 2**30     # GiB.
    disk_used = disk.used / 2**30
    disk_free = disk.free / 2**30
    disk_percent_used = disk.percent
    #
    # Print top five processes in terms of virtual memory usage.
    #
    print 'CPU temperature is: ',  cpu_temperature

fromaddr = 'myemailadress'
toaddrs  = 'myemailadress'
#msg = 'There was a terrible error that occured and I wanted you to know!'
msg = cpu_temperature

# Credentials (if needed)
username = 'myusername'
password = 'mypassword'

# The actual mail send
server = smtplib.SMTP('smtp.gmail.com:587')
server.starttls()
server.login(username,password)
server.sendmail(fromaddr, toaddrs, cpu_temperature)
server.quit()




if __name__ == '__main__':
    main()

running it gives the following error:

pi@raspberrypi /home/python $ python sendcpu.py
Traceback (most recent call last):
  File "sendcpu.py", line 36, in <module>
    msg = cpu_temperature
NameError: name 'cpu_temperature' is not defined
pi@raspberrypi /home/python $


isnt cpu_temperature defined?
