I consider myself an intermediate user in python, and this one is a new one. Testing code in IDLE (Python 3.2.3) on Linux. Here is the entire script:

I've navigated to the correct directory, and I'm importing from the same directory, and vec.py exists. Why is in not locating a file in the local directory? Running this script from a terminal window command line works correctly.
Suggestions?
use this..
import sys
sys.path.append("/home/bradfordgp/Documents/matrix")
import vec
import sys
sys.path.append("/home/bradfordgp/Documents/matrix")
import vec
Rather than change to the directory, just add the location to the places python will search on import
See more here
In interactive mode, import will try to import modules from the current directory after os.chdir. But in non-interactive mode, it will fail and still search from the previous directory. You can see more discussion from this issue. In non-interactive mode, you'd better do what others mention.

I'm trying to import volatility3 into my python project/script, so that I don't have to use os.system since volatility3 is already made in python3.
I'm wondering how can I import all the functions/modules of said project ? The functions I'm interested in are located in volatility3/volatility/framework
I tried simply putting:
>>> import volatility3.volatility.framework
But I get the following error:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/volatility3/volatility/framework/__init__.py", line 12, in <module>
from volatility.framework import constants, interfaces
ModuleNotFoundError: No module named 'volatility'
My guess is I have to modify sys.path or one of the path variables but this does not seem to work.
Thanks,
The best solution here would be to properly install volatility with pip3, from your already exiting repository folder:
$ pip3 install /home/volatility3
or directly from pipy (not tested):
$ pip3 install volatility3
then you should be able to import the from volatility package directly:

>>> import volatility.framework
>>> volatility.framework
<module 'volatility.framework' from '/home/bruno/.local/lib/python3.6/site-packages/volatility/framework/__init__.py'>
>>>
I'm trying to import multiple imports in one module, and then import that module and have everything I need imported. Can I do that?
I'm trying it like this:
>>> os.system('cat python_imports.py') # just to show the contents of a file
import sys
0
>>> import python_imports # now import
>>> sys # now use the imported stuff
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'sys' is not defined
So what to do if this doesn't work?
If someone didn't understand the question: When working with python shell; I'm using some same modules everytime, which need to be imported manualy. I don't want to import the same modules every time I start Python shell, I want to import them faster.
So is there any way of doing this?
Thanks!
It looks like you just want a convenient way to import modules into a shell session without a lot of tedious typing.

I have setup a fairly simple flask project. Within this flask project I want to use psutil but its not being found with the import statement.

The same can be said for just a straight forward python script being executed separately.
Standard python modules(subprocess, os, etc) are loading fine. I have tried to focus my google-fu on this but I am getting nowhere so would massively appreciate if anyone can point me in the right direction.
Cheers
Does your first line in satelite.py refers to the same python binary as which python in your terminal ?
(This refer to the #! line)
Maybe you are using python3 in your satelite.py file.
I recently tried installing powerline-vim, but have been running into problems with it.
Every time I open a new window, I see this error:
Error detected while processing function <SNR>9_UpdateWindows..<SNR>9_pyeval:
line 1:
Traceback (most recent call last):
File "<string>", line 1, in <module>

File "opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/uuid.py", line 545, in uuid4 from os import urandom as _urandom
ImportError: cannot import name urandom
When I delete this line from my .vimrc file (effectively disabling powerline-vim) the error goes away.
python from powerline.ext.vim import source_plugin; source_plugin()
The curious thing about this is when I fire up python from the terminal, the imports work just fine.

Thanks!
Check if your problem is related with that: Python: cannot import urandom module (OS X). Check your sys.path value. Make sure you import os module from your installation of Python, not from system Python.
Check the log configure generates when you build Python for clues. Have you specified prefix when building Python?
Edit the code and print os and sys.path just before the error occurs to check if the plugin changed something. If sys.path is modified, often you may find the place where it is by performing import sys; sys.path = tuple(sys.path). It does not crash on sys.path = smth, but crashes on append() and +=. Maybe that would be enough to show the place where path is modified.
The problem was I was executing the wrong version of Python.
sudo port select python python27-apple
Running that line fixed it.
Thanks!
I'm trying to import the tkinter module into my script. I have it installed since the interpreter is able to import it with no problems:
C:\Users\Nacht\Dropbox\Scripts>python
Python 3.2.2 (default, Sep 4 2011, 09:51:08) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import tkinter
>>>
Imports fine, no problem. But now when I try to run a script that has the line import tkinter....
C:\Users\Nacht\Dropbox\Scripts>t ls
Traceback (most recent call last):
File "C:\Users\Nacht\Dropbox\Scripts\t.py", line 5, in <module>
import tkinter
ImportError: No module named tkinter
where t is the name of the script and ls a command (it is a command-line interface).
How can the interpreter see it but not the script? Thanks.
EDIT:
The sys.path says, for the interpreter:
C:\Python32\lib\site-packages\distribute-0.6.24-py3.2.egg
C:\Python32\lib\site-packages\selenium-2.15.0-py3.2.egg
C:\Windows\system32\python32.zip
C:\Python32\DLLs

C:\Python32\lib\site-packages
C:\Python32\lib\site-packages\win32
C:\Python32\lib\site-packages\win32\lib
C:\Python32\lib\site-packages\Pythonwin
and for the script:
C:\Users\Nacht\Dropbox\Scripts
C:\Python27\lib\site-packages\distribute-0.6.24-py2.7.egg
C:\Windows\system32\python27.zip
C:\Python27\DLLs

C:\Python27
C:\Python27\lib\site-packages
C:\Python27\lib\site-packages\setuptools-0.6c11-py2.7.egg-info
The script appears to be running with Python 2.7 but when you run the interpreter directly, it is using Python 3.2. As mentioned by #DSM, the name of Tkinter was different (perhaps there are other differences?).
May be there is a problem with path. It can't find the tkinter module. Setting up correct path try to import again.
