SyntaxError: invalid syntax (windows)
I'm a total newbe to scripting not to mention python. However I was able to
successfully create a telnet script to initiate login, initiate tftp, exit,
exit, confirm and close session. Frustrated, possibly causing my own misery.
I replace the sript the script with the standard example.
import getpass
import sys
import telnetlib
HOST = "remote linux"
user = raw_input("Enter your remote account: ")
password = getpass.getpass()
tn = telnetlib.Telnet(HOST)
tn.read_until("login: ")
tn.write(user + "\n")
if password:
tn.read_until("Password: ")
tn.write(password + "\n")
tn.write("ls\n")
tn.write("exit\n")
print tn.read_all()
Regardless of the script content, running in windows I constently get this
SyntaxError:
C:\Python30>python c:\Python30\scripts\telnet.py
File "c:\Python30\scripts\telnet.py", line 20
print tn.read_all()
^
SyntaxError: invalid syntax
C:\Python30>
The same script works fine from linux.
I have also notices some other slight differences: this is my original
script that runs and completes but only if I comment out print. Also tried
to run debug without success in windows again this worked fine in linux. To
run this script in linux I also had to remove the b syntax in the "b" in the
perentesis
import telnetlib
# import pdb
HOST = "HP switch"
tn = telnetlib.Telnet(HOST)
tn.read_until(b'Password: ')
tn.write(b'password\n')
pdb.set_trace()
tn.read_until(b'HP switch# ')
tn.write(b' sh time\n')
tn.read_until(b'HP switch# ')
tn.write(b'exit\n')
tn.read_until(b'HP switch> ')
tn.write(b'exit\n')
tn.read_until(b'Do you want to log out [y/n]? ')
tn.write(b'y')
print tn.read_all()
Any guidance would be appreciated.

Re: SyntaxError: invalid syntax (windows)
Thats newbe experience for ya ;-) thanks. Its seems to work and leads to
another question. whether running the script or stepping thru the process at
the command line I get what looks like hex
C:\Python30>python \Python30\scripts\telnet-tftp1.py
b'\x1b[24;1H\x1b[24;31H\x1b[24;1H\x1b[?25h\x1b[24;31H\x1b[24;31Hy\x1b[24;31H\x1b

x1b[?25h\x1b[24;1H\x1b[1;24r\x1b[24;1H\x1b[2J\x1b[?7l\x1b[1;24r\x1b[?6l\x1b[24;1

1b[24;1H\n\r'
C:\Python30>
I can verify the script ran thru and executed the telnet commands. is there
a switch to convert to binary/ASCI or reduce the logging of the telnet
session ???
Thanks again

There's the clue:
In python 3.X, print is a function call
print(tn.read_all() )
with lots of formatting and line-ending features
In python 2.X, print is a statement:
print tn.read_all()
If you want one script to work for both Windows and Linux, then you should
probably
be running the same version of Python on each. At least both versions
should be on
the same side for the Python 2.x/3.x version change.

Re: SyntaxError: invalid syntax (windows)
Gotcha, I got started from the telnet example listed in the docs. The linux
install was via yum and installed 2.x instead. That explains it. Althought
print (tn.read_all () ) runs in 2.x on linux.
I have another problem maybe you cna help me with. My telnet output
jibberish in windows: I cna parse some of the output for results but is
there anyway to get rid of the jibberish. (looks like hex but I'm not sure)
I can only use this tn.read_until(b'whatever string') Is this whats causing
the output? the b switch. seems like I don't need it in linux. is that
binary?
Thanks

It looks like you're using Python 3.0 on Windows and Python 2.x on
Linux.
In Python 2.x, 'print' is a statement:
print tn.read_all()
In Python 3.x, 'print' is a function, so you need to write:
print(tn.read_all())
