Can't use the import os command in python - python

I'm using the python compiler in java and I tried import os .
My problem is when I couldn't input it to continue the next line while it just sent back this message os is not yet implemented in skulpt on line 1 .
I already tried with another app and still get a same result. I tried to search Google but no result. I read in learning web and it's never seem the existence of this error.
What is skulpt? Please help me

To find which standard modules the most recent version of skulpt supports and which it doesn't, get a copy of the source code:
git clone https://github.com/skulpt/skulpt.git
And, look through the src/lib directory. Every successfully implemented module will be a directory in /src/lib. os is not one of those directories. Module os is not implemented in skulpt.

Python scratch files in Pycharm - modules not being found?

I'm new to Python and using PyCharm professional as my IDE. I have a small section of code that I want to work with from a longer file, so I created a "scratch file" with Python set as the interpreter. However, even just with importing modules I'm getting errors that the modules can't be found (even with standard modules). The file is set as a "Python" scratch file, so I'm not sure what else I need to do. The code I'm trying to run is:
from zipfile import ZipFile
import urllib
testfile = urllib.request.urlretrieve("https://ihmecovid19storage.blob.core.windows.net/latest/ihme-covid19.zip", "ihme-covid19.zip")
print("File saved at: " + (str(os.getcwd())))
with ZipFile('ihme-covid19.zip', 'r') as zipobj:
print(zipobj.printdir())
zipobj.extractall()
Everything is showing up with an error - no module urllib, no module zipfile, etc.
This may come across like a non-answer, but I do think this is a bug in Pycharm.
I even downloaded an update, restarted pycharm, and rebuilt my indexes. Same thing, here -- core Python modules are not registering as being importable (i.e. import sys or import inspect both failing type-checking).
We should probably move this to Pycharm's bug tracker. For example:
Here is a similar issue around a specific import NamedTuple
Here's an issue around the default interpreter in scratch files
There may be a better existing bug ticket, so please do look and report back here -- I'll update this comment if someone finds or creates a better bug ticket on youtrack.jetbrains.com and shares the link.

Is it possible to specify the search path for a module in a python script? If it is, how do I do that?

I have been coding in python for about 2 months, but I'm only familiar with basic object-oriented programming, so I do not really understand things like how searching for modules is implemented. (Basically I'm a noob.)
I pip installed a package called Opentrons Opentrons 2.5.2 and all its dependencies into the samefolder as a python script I'm currently writing. However when I tried to import the module below[1], I get an error saying that "Opentrons is not a module". Then, I tried shifting it into the python library because I found out the search path using the pprint module and it seems to work. I was wondering if I can specify the search path from the .py file itself instead of manually printing the search path and putting the file into the library that the script searches for. (Willing to put in images of the directories I put the opentrons package in if it helps.)
[1]
import sys
import pprint
pprint.pprint(search.path)
from opentrons import robot, containers, instruments
Edit: I realise that the fact that I am running all my scripts in a Spyder console located in a python 3.6 environment might be important.
You can try using the __import__ function, or importlib. This should allow you to specify the path.

Including xlrd/xlwt/xlutils with modules outside of python installation

I'm self-taught in the Python world, so some of the structural conventions are still a little hazy to me. However, I've been getting very close to what I want to accomplish, but just ran into a larger problem.
Basically, I have a directory structure like this, which will sit outside of the normal python installation (this is to be distributed to people who should not have to know what a python installation is, but will have the one that comes standard with ArcGIS):
top_directory/
ArcToolbox.tbx
scripts/
ArcGIStool.py (script for the tool in the .tbx)
pythonmod/
__init__.py
general.py
xlrd/ (copied from my own python installation)
xlwt/ (copied from my own python installation)
xlutils/ (copied from my own python installation)
So, I like this directory structure, because all of the ArcGIStool.py scripts call functions within the pythonmod package (like those within general.py), and all of the general.py functions can call xlrd and xlwt functions with simple "import xlrd" statements. This means that if the user desired, he/she could just move the pythonmod folder to the python site-packages folder, and everything would run fine, even if xlrd/xlwt/xlutils are already installed.
THE PROBLEM:
Everything is great, until I try to use xlutils in general.py. Specifically, I need to "from xlutils.copy import copy". However, this sets off a cascade of import errors. One is that xlutils/copy.py uses "from xlutils.filter import process,XLRDReader,XLWTWriter". I solved this by modifying xlutils/copy.py like this:
try:
from xlutils.filter import process,XLRDReader,XLWTWriter
except ImportError:
from filter import process,XLRDReader,XLWTWriter
I thought this would work fine for other situations, but there are modules in the xlutils package that need to import xlrd. I tried following this advice, but when I use
try:
import xlrd
except ImportError:
import os, sys, imp
path = os.path.dirname(os.path.dirname(sys.argv[0]))
xlrd = imp.load_source("pythonmod.xlrd",os.path.join(path,"xlrd","__init__.py"))
I get a new import error: In xlrd/init.py, the info module is called (from xlrd/info.py), BUT when I use the above code, I get an error saying that the name "info" is not defined.
This leads me to believe that I don't really know what is going on, because I thought that when the init.py file was imported it would run just like normal and look within its containing folder for info.py. This does not seem to be the case, unfortunately.
Thanks for your interest, and any help would be greatly appreciated.
p.s. I don't want to have to modify the path variables, as I have no idea who will be using this toolset, and permissions are likely to be an issue, etc.
I realized I was using imp.load_source incorrectly. The correct syntax for what I wanted to do should have been:
imp.load_source("xlrd",os.path.join(path,"xlrd","__init__.py"))
In the end though, I ended up rewriting my code to not need xlutils at all, because I continued to have import errors that were causing many more problems than were worth dealing with.

Error importing modules from gdata

I'm using virtualenv with my application, and I've installed gdata, jira, and gspread using env/bin/pip install <lib name> in terminal under my project folder. I'm following the documentation from the Google API but it is not working?
In the documentation, in order to do error handling you need to do:
from gdata import errors
And in order to create an instance of the Drive API service (in order to later on create a file) you need to do:
from gdata.discovery import build
However the files are different, there is no "discovery" or "errors" and when I run env/bin/python run.py I get this error:
Traceback (most recent call last):
File "run.py", line 3, in <module>
from gdata import errors
ImportError: cannot import name errors
(same with discovery)
I thought that maybe they mean from apiclient import errors literally in the documentation, so I tried pip installing apiclient and replacing gdata with apiclient but it still does not work.
I downloaded the gdata.zip file and unzipped it and looked through the sample code (especially for spreadsheet since that's what I'm trying to create) and they take a very different approach than the documentation and I'm very confused. My goal is to use their API to just create a spreadsheet from the code, but I do not plan on using their API to edit the spreadsheet itself, I plan on using gspread (Github).
I've done a lot of research and I've been directed to a lot of different places and I might have perhaps mixed up the code? Does anyone know what I did wrong/have a fix? A huge thanks in advance.
This kind of import error is usually caused by the user installing another module of the same name. Do you by any chance have a gdata.py somehwere on your Python path?
You can verify whether this is causing the issue by:
import gdata
print gdata.__file__
This tells you where the interpreter is loading the code from.

How to call a python file, that needs to import packages?

I'm following a tutorial to call python code from a C++ program from the python docs.
Everything works just fine when trying to call the multiply example. Now if I add a line to the python source code importing a library, lets say openpyxl,
from openpyxl import load_workbook
I receive an error from python
ImportError: No module named openpyxl
I thought if I import a system library, I wouldn't have any problems, but I also get an error if I try to import datetime.
I don't have any error if I import the file from the python console. The openpyxl library is installed in my system.
So my question is: how to import python source code that needs to import packages?
EDIT: Ok, I forgot to mention something, I have not been completely honest with you guys, I'm sorry.
Trying to run the example I run into a problem: I couldn't make python found my multiply.py file, and the line PyImport_Import always return null.
My solution was to add the path in which I knew my python source was by using PySys_SetPath. The problem is that I just realized that this function doesn't append a new directory, it just overwrites the PYTHONPATH. So now python can find multiply.py, but absolutly anything else.
Of course I've deleted that line but now I have another question, why does python can't find my source if the file is just in the same directory of the C++ compiled program?
The I realized that my sys.path from my python console was a little different from the path showed in my embedded python: the first one had at the beginning of the list an empty string ''. I'm not a python expert, but when I add that line to my path I could import the multiply.py so it seems that was the reason I couldn't import modules that were located to relative to my executable was the missing of this empty path -but still don't know what it means-.
I have to thank to #paul-evans who give me the idea of adding the path to find my files.
This is what PYTHONPATH is for. You can set it as an environment variable containing a list module directories, or in the code itself something like:
import sys
sys.path.append("path/to/openpyxl/module")
