[SOLVED]Python script keeps getting SyntaxError: invalid syntax

dreadz · 2014-02-25 15:02:50

Hi, i am trying to run a python script, but every time i try to run it

with ./unlocker.py i get

File "./unlocker.py", line 31
print 80 * "*"
^
SyntaxError: invalid syntax

dreadz ~ > which python
/usr/bin/python

I have consulted with the wiki, and attempted all solutions there

to deal with the enviroment problems. If i use virtualenv2 i get this

Traceback (most recent call last):
File "./unlocker.py", line 27, in <module>
import time, serial, re, hashlib, glob
ImportError: No module named serial

(venv)dreadz ~/builds > which python
/home/dreadz/builds/venv/bin/python
(venv)dreadz ~/builds >

The script runs on a solaris system but not on mine.

Maybe someone can point me to a solution ?

dreadz ~/builds > uname -a
Linux ufoo 3.13.5-1-ARCH #1 SMP PREEMPT Sun Feb 23 00:25:24 CET 2014 x86_64 GNU/Linux

Thanks

Are you running Python2 on one system and Python3 on another?

dreadz · 2014-02-25 15:24:29

The solaris system is in the uni, so i don't know

what version of python is running there.

That's what i have on mine

dreadz ~/builds > python --version
Python 3.3.4

The version of Python on Solaris is almost certainly Python 2.

print 80 * "*"

This is correct syntax for Python 2.

This is NOT correct syntax for Python 3. In Python 3, "print" is a function.

If i change the shebang line to:

#!/usr/bin/env python2

i get the Traceback error.

If i run with

python2 script.py

i get the same error.

The error is extremely descriptive. Read it again. What is it telling you? What might that mean? What would be the most reasonable solution?

I don't mean to be dissrespecting but i have read the error and it is not descriptive to me.

I don't have experience with python, i am only trying to run a script that i know for a fact can

run on another system. I know it is something to do with my env path and the solutions to simmilar

problem described in the wiki do not work on my system.

"ImportError: No module named serial" is pretty clear, you don't have the serial module installed.

"No module name serial" means there is no module named "serial".

If you want to use a module named "serial" then you will need to install a module named "serial". Keep in mind that the module will need to be installed for Python 2.

Thanks for pointing this out. I have installed python2-pyserial and now i can run the script.

Thanks for your patience and advice!

You're welcome. You can add "[SOLVED]" to the title of this thread by editing your original post.

Yeah, even after all this time Arch Linux is STILL one of the only distributions that switched to Python 3 as the default version. Tricky Arch Linux. Keeps me on my toes.
