I use Python 3.5 and I have installed cloudant package by an execute command:

sudo -H pip3 install cloudant

I try to connect with python database. According to the documentation - https://console.bluemix.net/docs/services/Cloudant/getting-started.html#getting-started-with-cloudant. This code should works:

from cloudant.client import Cloudant

client = Cloudant("username", "password", url="https://user_name.cloudant.com")
client.connect()
client.disconnect()

When I run it I get an error: 

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/tomek/Projects/stage-control/cloudant.py", line 1, in <module>
    from cloudant.client import Cloudant
ImportError: No module named 'cloudant.client'; 'cloudant' is not a package

  • Type `pip show cloudant` on the command line. What is reported? If nothing, then the package isn't installed. Also, you rarely want to install packages with `sudo`. Just do it as your normal user. See [What are the risks of running 'sudo pip'?](https://stackoverflow.com/questions/21055859/what-are-the-risks-of-running-sudo-pip) – Raj Oct 31 '17 at 23:34

I suspect your problem may be that the pip used to install the module isn't the pip that your python is using:

If I do pip3 install cloudant I get the same problem as you:

(py35) stefans-mbp:work stefan$ python
Python 3.5.3 |Anaconda 4.4.0 (x86_64)| (default, Mar  6 2017, 12:15:08) 
[GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.57)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> from cloudant.client import Cloudant
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named 'cloudant.client'

This is because of this:

(py35) stefans-mbp:work stefan$ which pip
//anaconda/envs/py35/bin/pip
(py35) stefans-mbp:work stefan$ which pip3
/usr/local/bin/pip3

The wrong pip3 was used to install the cloudant module. To remedy, ensure you use the pip in the virtual env you're using:

(py35) stefans-mbp:work stefan$ pip install cloudant
Collecting cloudant
Using cached cloudant-2.7.0.tar.gz
Requirement already satisfied: requests<3.0.0,>=2.7.0 in 
/anaconda/envs/py35/lib/python3.5/site-packages (from cloudant)
Building wheels for collected packages: cloudant
  Running setup.py bdist_wheel for cloudant ... done
  Stored in directory: ...
Successfully built cloudant
Installing collected packages: cloudant
Successfully installed cloudant-2.7.0

Now it works:

(py35) stefans-mbp:work stefan$ python
Python 3.5.3 |Anaconda 4.4.0 (x86_64)| (default, Mar  6 2017, 12:15:08)

>>> from cloudant.client import Cloudant

Just rename your file cloudant.py to something else.

Are you running locally or in an app on Bluemix? There must be something wrong with your install, because the code looks fine. This code runs for me:

from cloudant.client import Cloudant
from cloudant.document import Document

client = Cloudant("username", "pw", url="https://username.cloudant.com")
client.connect()
thedb = client["databasename"]
for document in thedb:
    print(document)
client.disconnect()

If you're running on Bluemix, make sure you have a requirements.txt file to trigger library imports. See https://pip.readthedocs.io/en/1.1/requirements.html
