I'm trying to make a bot for Telegram on my RPi but I'm pretty new to this. I installed Telegram Cli and pexpect.
This is my test.py file:
import pexpect
telegram = pexpect.spawn('./telegram -k tg.pub')
telegram.expect("User")
telegram.send("msg Big_Boss test")
However this give me the following error:
Traceback (most recent call last):
File "test.py", line 5, in <module>
telegram.expect("User*")
File "/usr/local/lib/python2.7/dist-packages/pexpect/__init__.py", line 1451, in expect

timeout, searchwindowsize)
File "/usr/local/lib/python2.7/dist-packages/pexpect/__init__.py", line 1554, in expect_loop
raise EOF(str(err) + '\n' + str(self))
pexpect.EOF: End Of File (EOF). Exception style platform.
I couldnt find any good documentation about the expect function. Basically what I am trying to do is send X when someone messages me something containing Y. But I can't get the first thing working. Simply sending a command.
Here's a Pexpect tutorial, and some sample code:
source
import pexpect
calc = pexpect.spawn('bc')
calc.expect("details")
print calc.send("1+2")
output

I have written a short python script that uses bleak and asyncio to control a bluetooth LE device. The script works exactly as intended when I run it manually in pycharm or terminal, however I want to run it at specific intervals using crontab.
I've searched for a solution and tried adding absolute paths as well as logging errors. I have found that the script throws an error when run from crontab but I don't quite understand how to fix it.
Here is the script:
#!/usr/bin/python
from bleak import BleakClient
import asyncio
address = "DFB18A2C-6BAB-439E-AF05-485FB4259B75"
MODEL_NBR_UUID = "99FA0002-338A-1024-8A49-009C0215F78A"
async def main(address):
async with BleakClient(address) as client:
for i in range(3):
await client.write_gatt_char(MODEL_NBR_UUID, bytes.fromhex("0800"))
time.sleep(0.5)
asyncio.run(main(address))
And here is the error from crontab log:

I'm running MacOS btw!
Thanks in advance!
remove that command from your cronjob.
do this, select your editor of choice from the list.
sudo crontab -e
then add your cronjob, exit and then save (these will run as root)

This happens when you have bluetooth off on your OSX device.
I'm working on interfacing an old Optical Spectrum Analyzer Anritsu MS9710B with a RS232 connection. A year ago, I managed to comunicate with him, send SCPI command using pyvisa and receive data. Today, I execute the exact same code with libraries up to date and I get an error Timeout when I query IDN or anything. The RS232-USB drivers are ok, I manage to open a communication but a query or read fail.
I changed the parameter to "RS232C" on the OSA parameters and my communication parameters are the same between OSA and program. Following advices from the forum, I tried the connection with NI-VISA where I get the same error. I tried to change timeout parameter, write_termination and read_termination but there isn't any change. The manual is very hard to understand termination value, but when it worked I didn't add anything.
I don't know anymore what to do.
Any advices and help would be warmly welcome to fix my problem !

I'm getting error in trying to communicate in a group chat via skype.
Traceback (most recent call last):

[Finished in 7.483s]
I'm just trying to test to send a simple chat to a groupchat but I'm not sure what is causing this error.
currently using this code
ch = sk.chats["19:***********************#thread.skype"] //due to privacy issue, i cant display the id
ch.sendMsg("testing")
whereas if I use the code this way for creating a new conversation,
ch = sk.contacts["live#123"].chat
ch.sendMsg("testing")
it will work.
Can someone enlighten me what is the issue with it? really appreciate a lot.
I am trying to use pexpect module (version 3.3) with Python 3.4.0. I get an error
TypeError: must be str, not bytes
when I call child.expect method.
Actual code is standard example from pexpect documentation:
child = pexpect.spawn('ssh foo#bar.com')
index = child.expect([pexpect.TIMEOUT, pexpect.EOF, ssh_newkey, '.*password:'])
Exactly the same code works properly with pexpect module (version 3.1), and Python version 2.7.6.
Pexpect documentation on GitHub states that pexpect version 3.3 requires Python 2.6 or 3.2 or above. Does anybody know if pexpect does not work with Python 3 for some reason despite what is stated in documentation for this module?
This is traceback output that I get:

raise TypeError('must be str, not ' + type(s).__name__)
TypeError: must be str, not bytes
Additionally, I also see "OpenSSH" box pop open via GUI on Ubuntu prompting for password when I run the script. This does not happen under Python 2.7.6. In Python 2.7, I can login into system without any manual interaction - everything happens automatically via script.
From the documentation:
# In Python 3, spawnu should be used to give str to stdout:
child = pexpect.spawnu('some_command')
child.logfile = sys.stdout
I've been learning to use python in astronomy and for that I'm following this notes. In the very beginning the author does the following example:
>>> im = pyfits.getdata('http://das.sdss.org/www/cgi-bin/drC?RUN=3630&RERUN=40&CAMCOL=3&FIELD=83&FILTER=r')
>>> numdisplay.display(im,z1=1000,z2=1500)
I try to replicate it and I get:
>>> numdisplay.display(im,z1=1000,z2=1500)
Image displayed with Z1: 1000 Z2: 1500

I don't understand what I'm doing wrong. I mean if I write numdisplay.open() everything is fine... I'm thinking that it might be my antivirus or something that doesn't let python to communicate with ds9... Can somebody help me?
Edit: Well it doesn't seem to be the antivirus. I stopped it and run the script and I got the same error.
I was getting similar error messages, and I just tried adding a non-'None' argument to the bufname argument and it works (my image is about 4096.4096):
numdisplay.display(data,bufname='imt4096')
