unexpected EOF while looking for matching `'': What does this mean?

these are the error messages I am receiving from the terminal when I run add_user.py
sh: -c: line 0: unexpected EOF while looking for matching `''
sh: -c: line 1: syntax error: unexpected end of file
After some reading online I am led to believe that these errors are thrown when I am missing a matching parenthesis or quotation mark?I have looked through the file several times but since it has been a few hours, I might just be looking straight over the error. If it is not a missing quotation mark or parenthesis, please explain what might be causing the issue so I can fix it. Thanks to all who help!

how to telnet huawei switch with python script?

I want to telnet huawei switch with python script to read some basic staff like "display int brief" result. I know basic huawei command and some programming.
I can telnet cisco router with python script.
Here is my attempt so far
import telnetlib
import datetime
now = datetime.datetime.now()
host = "myhost" # your router ip
username = "user" # the username
password = "pass"
tn = telnetlib.Telnet(host,23,6)
tn.read_until("Username:")
tn.write(username+"\n")
tn.read_until("Password:")
tn.write(password+"\n")
tn.write("display int description"+"\n")
#tn.write("sh run"+"\n")
tn.write("quit"+"\n")
output = tn.read_all()
fp = open("sw_hu.txt","w")
fp.write(output)
fp.close()

I would use pexpect library then open connection with pexpect.spawn('telnet ip_address') module documentation is great start. If you now commands then it is mostly combination off sendline, expect and before.
child = pexpect.spawn ('telnet %s' % dev_name)
try:
i = child.expect_exact(['Password:', 'Username:'])
except (pexpect.EOF, pexpect.TIMEOUT):
return False
if i == 1:
child.sendline(user_name)
child.expect_exact('Password:')
child.sendline(passw)
else:
child.sendline(passw)
if child.expect_exact(['>', 'Wrong', pexpect.TIMEOUT], timeout=5):
child.close()
return False
child.sendline('sup')
i = child.expect_exact(['Password:', '>', 'Unknown', 'not set'])
if i == 1:
child.sendline('')
elif i == 2 or i == 3:
child.close()
return False
else:
child.sendline(ena)
if child.expect_exact(['>', 'Password', 'failed']):
child.close()
child.sendline('tftp %s put %s %s.backup.txt' % (TFTP, conf_name, name))
child.expect_exact(['>', 'successfully'])
if 'Unable' in child.before:
....
....
Edit: Added partial example to backup config (it is python 2.x and old Huawei router)

if w['router_type'] == "cisco":
tn.read_until("Username:")
tn.write(user.encode('ascii')+"\n"

tn.write(password.encode("ascii") + "\n")(indent)
tn.write("terminal length 0\n")
tn.write("show version\n")

tn.write("exit\n")
tn_output = tn.read_all()
print ("Logging out Router ") + w['host_name'] + ("_") + w['router_type'] + (".....")
flag = 1

Python 2.7.12 netaddr.IPNetwork AddrFormatError

Version: Python 2.7.12
OS: Ubuntu 16.04.1

Arch: ppc64le
netaddr.IPNetwork fails with:
netaddr.core.AddrFormatError: invalid IPNetwork '9.2.0.0/16'
I have a function:

I discovered my problem.
I was passing a quoted network address and IPNetwork was failing when trying to convert the octet from of ip address into decimal format because the first octet had the string quote in it.

Python 3 ASCII code 219 issue

I compared code to other training example code out there and did a compare and everything matches. Here is my issue: I have a health bar and when I take damage the bar decreases.
The problem is when in my code I use █ the pipe line after the bar never stays put, it always move dynamically. When I use / the pipe bar always stays put and no issue. I'm guessing there is something in my terminal tool (using Pycharm) that it doesn't like ascii code 219. If it matters from reading forums the tool is set to UTF-8. example below so might not format correctly but top part you can see the | being shifted when using █ and the bottom part is fine when using /.

You have to change your font type
Navigate to File -> Settings -> Editor -> Font
Font: Source Code Pro
Apply -> Ok
Rerun the program

Try the following at the top of your script:
import sys
reload(sys)
sys.setdefaultencoding('utf8')

I want black.py module to be called in main.py but when I am running main.py I am getting the following error:

Enter your choice [0-24] : 0
Traceback (most recent call last):
File "./main.py", line 131, in <module>
pPODName()
NameError: name 'pPODName' is not defined

pPODName has not been defined as far as main.py can tell.
Firstly
pPODName is defined within another function, so only that function is aware of it. This is referred to as being in local scope. Basically anything defined within a function is only accessible to that function, and nothing else.
For an example:
def test():
def test_local():
return 3
return test_local()
Running the function test gives you
>>> test()
3
However running the function test_local
>>> test_local()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'test_local' is not defined
Secondly
Secondly, when importing modules, you need to either qualify them with the module name, like you have done with black.blackout(), of you need to use:
from black import *
Although personally I don't like that, it makes it hard to see where methods are coming from.
Fix
For main.py to be able to call pPODName, it must be defined within the module as a whole, e.g.:
def blackout()
#do stuff here
def pPODNAME()
#do other stuff here
#note the indentation level is the same as blackout
and you must call it with
black.pPODName()
From main.py

You have some programming hierarchy level mistake
why pPODName is inner function of blackout ?
and has James said- if you are using outer and inner function the outer needs to call the inner.
I suggest you to use regular function in black.py
blackout function does nothing except containing the pPODName so you don't need it
