I installed Ibpy2 to connect to my interactive broker account.
https://github.com/blampe/IbPy
I installed IbPy2 successfully (by installing pip install IbPy2 AND python setup.py install).
However, when I open Spyder in Anaconda and run from IBWrapper import IBWrapper, contract. It says:
No module named 'IBWrapper'.
Please advise how I may fix it. Many, many thanks!
IbPy is outdated, it's a 3rd party module that's no longer supported as there is an official Python module available.
If you wish to use a IbPy like interface to interact with the official API, use IbPythonic. It's almost identical to IbPy with minor adjustments, for example IbPy has 'm_' prefixes in functions.
Please refer to https://github.com/anthonyng2/ib It is third party python file that you may directly code
from IBWrapper import IBWrapper, contract
You need to download the IBWrapper.py file and copy it into your python library path.

i am not able install 'copyleakscloud' library. I already installed 'copyleaks' library, but i need 'copyleakscloud' and i'm not getting any version of this library. please help!
Are you talking about this library?
You need to open a prompt (cmd on Windows or Terminal on macOS) and run
pip install copyleaks
The CopyleaksCloud is bundled with the copyleaks library. You can use it with the following code lines:
from copyleaks.copyleakscloud import CopyleaksCloud
cloud = CopyleaksCloud('ProductName', 'YOUR_EMAIL_HERE', 'YOUR_API_KEY_HERE')# You can change the product.
I'm a complete beginner in Python programming. I have trouble installing/importing the module 'requests' on python. When I use my command terminal to install requests, I get a message that requests is already installed. However, when I try to import requests into the file I'm working on, python tells me there is no such module installed.
Sorry to bother you with this silly and probably easy question, thanks in advance!
If you use PyCharm (which is a great choice in my opinion), go to the tab Run and select Edit Configuration and in the window that just opened make sure the your Python interpreter is the one you used when you pip installed the package you asked about.
You can check your Python version or just see in PyCharm if the requests is actually installed by going to the tab File, select Settings, click on Project: name_of_your_project and finally check in Project Interpreter that the package is installed.
I'm struggling with executing a python script on my freenas (freebsd) environment.
I created a Jail, where I installed python via
pkg install python
and tried to execute the program with the command
python filename.py
But now its mentioning that it requires a specific module
ImportError: No module named simplejson
which I also installed via
pkg install ...
the next attempt to execute the script mentioned a different module.
Is it really the case for python, that you have to install each module per request from an executed program? Or is there a way to determine which module the 3rd party program needs and install it in upfront?
And how do you search for the corresponding module in the repo? Because for the missing sqlite3 module I had to write
pkg install databases/python-sqlite3
How do I get now the correct name for the simplejson module which is mentioned before?
Can you help me out there?
The first questions where already answered in the comments section. Here is the answer to the last question:
FreeBSD ports of python modules usually follow the convention of "py-" + modulename. The corresponding packages are usually named "py"+ python version + "-" + modulename
So it is py-sqlite3 and py-simplejson ports which install "py27-simplejson" and py27-sqlite3 for python 2.7.
Note: currently modules are only packaged for the default python version, for non-default python versions the modules have to be installed from the ports collection.
I got this simple problem and I can't find the answer anywhere, I'm wasting a lot of time!
I did a Python programm on Linux (which works OK), but when I try to run it on Windows, there are too problems with libs...
I have installed the libs I need (dateutil, lxml, xmlrpclib...) in C:\Python34\Lib\site-packages. But then, they don't work as they do on Linux. For example:
from dateutil.tz import tzlocal
Gives me next error:
File "C:\Python34\lib\site-packages\dateutil\tz.py", line 9, in module
from six import string_types, PY3 ImportError: No module named 'six'
That is, they are not finding the other modules... why???
Have you try this ?

Maybe it can help
It looks like you're using Python 3.4 which comes with pip. pip is a tool for installing packages and any dependencies they might have (like the srting_types module from your error message). I'd suggest learning how to use it because it resolves most of the packaging problems with you needing to moving things around yourself. See an answer from a different question to learn more about pip.
There are some packages that need to be compiled. This can be difficult on Windows 7 if you don't have the proper toolchain set up to compile packages. I'd recommend Christoph Gohlke's wonderful collection of installable packages for Windows. You just need to make sure to grab the right version. Since 3.4 is still relatively new, some packages may not be available, so be warned.
I'm just starting out with Python, and have found out that I can import various libraries. How do I find out what libraries exist on my Mac that I can import? How do I find out what functions they include?
I seem to remember using some web server type thing to browse through local help files, but I may have imagined that!
From the Python REPL (the command-line interpreter / Read-Eval-Print-Loop), type help("modules") to see a list of all your available libs.
Then to see functions within a module, do help("posix"), for example. If you haven't imported the library yet, you have to put quotes around the library's name.
For the web server, you can run the pydoc module that is included in the python distribution as a script:
python /path/to/pydoc.py -p 1234
where 1234 is the port you want the server to run at. You can then visit http://localhost:1234/ and browse the documentation.
Every standard python distribution has these libraries, which cover most of what you will need in a project.
In case you need to find out if a library exists at runtime, you do it like this
try:
import ObscureModule
except ImportError:
print "you need to install ObscureModule"
sys.exit(1) # or something like that
You can install another library: yolk.
yolk is a python package manager and will show you everything you have added via pypi. But it will also show you site-packages added through whatever local package manager you run.
just run the Python interpeter and type the command
import "lib_name"
if it gives an error, you don't have the lib installed...else you are good to go
On Leopard, depending on the python package you're using and the version number, the modules can be found in /Library/Python:
/Library/Python/2.5/site-packages
or in /Library/Frameworks
/Library/Frameworks/Python.framework/Versions/Current/lib/python2.6/site-packages
(it could also be 3.0 or whatever version)...
I guess it is quite the same with Tiger
Considering that in every operating system most of python's packages are installed using 'pip' (see pip documentation) you can also use the command 'pip freeze' on a terminal to print a list of all the packages you have installed through it.
Other tools like 'homebrew' for macOS (used when for some reason you can't install a package using pip) have similar commands, in this specific case 'brew list'.
