Getting Python Error "From: Can't Read /Var/Mail/Bio"

Getting Python error from: can't read /var/mail/Bio

No, it's not the script, it's the fact that your script is not executed by Python at all. If your script is stored in a file named script.py, you have to execute it as python script.py, otherwise the default shell will execute it and it will bail out at the from keyword. (Incidentally, from is the name of a command line utility which prints names of those who have sent mail to the given username, so that's why it tries to access the mailboxes).

Another possibility is to add the following line to the top of the script:

#!/usr/bin/env python

This will instruct your shell to execute the script via python instead of trying to interpret it on its own.

from: can't read /var/mail/docx

It's not finding your Python path or you're not using python command. Try running the script using python.

python script.py

Otherwise put the following line on top of your program:

 #!/usr/bin/env python

from: can't read /var/mail/boto.s3.connection

Looks like you are trying to execute your Python program in shell. Either add

#!/bin/env python

as the first line or run it in python explicitly

python whatever.py

Beautiful Soup 4 import error? install error?

Script should be executed as -

python spider2.py

instead of -

./spider2.py

from: can't read /var/mail/Adafruit_MotorHAT

First check, whether python is on you system:

edwards-iMac:~$ which -a python
/System/Library/Frameworks/Python.framework/Versions/2.7/bin/python
/usr/bin/python

To enter live interpreter do this on your commandline:

python

Now you are in the shell (Live Interpreter).
Then you can enter the following line by line:

from Adafruit_MotorHAT import Adafruit_MotorHAT, Adafruit_DCMotor

import time
import atexit

mh = Adafruit_MotorHAT(addr=0x60)

def turnOffMotors():
    mh.getMotor(1).run(Adafruit_MotorHAT.RELEASE)
    mh.getMotor(2).run(Adafruit_MotorHAT.RELEASE)
    mh.getMotor(3).run(Adafruit_MotorHAT.RELEASE)
    mh.getMotor(4).run(Adafruit_MotorHAT.RELEASE)

atexit.register(turnOffMotors)
