Python – ImportError: No module named IPython

ipythonpythonpython-2.7

When i try to use from IPython.display import clear_output, display_html, then i show the error:

Error Image
(ImportError: No module named IPython)

I am using Python 2.7.13, and im trying to make the game of life from John Conway. I am following this link: http://nbviewer.jupyter.org/url/norvig.com/ipython/Life.ipynb

I have read another questions and answers about it, but any answer works for me. First, this error is showed in command line, and when i try to run this code in a file. Second, this error is direct to IPython, not submodule or something similiar.

Ok, finally i achieved my goal.

I wrote ipython --version but i found, it was not installed.
I tried to install it, with pip. I went to C:\Python27\Scripts, here is pip, you can try in this directory, or add to environment variables.
I tried to install ipython, but i found a error

error: Unable to find vcvarsall.bat

so i installed visual studio c++ 9.0, the version to python 2.7.

pip install ipython

Python – Calling a function of a module by using its name (a string)

Assuming module foo with method bar:

import foo
method_to_call = getattr(foo, 'bar')
result = method_to_call()

You could shorten lines 2 and 3 to:

result = getattr(foo, 'bar')()

if that makes more sense for your use case.

You can use getattr in this fashion on class instance bound methods, module-level methods, class methods... the list goes on.

Python error “ImportError: No module named”

Based on your comments to orip's post, I guess this is what happened:

You edited __init__.py on windows.
The windows editor added something non-printing, perhaps a carriage-return (end-of-line in Windows is CR/LF; in unix it is LF only), or perhaps a CTRL-Z (windows end-of-file).
You used WinSCP to copy the file to your unix box.
WinSCP thought: "This has something that's not basic text; I'll put a .bin extension to indicate binary data."
The missing __init__.py (now called __init__.py.bin) means python doesn't understand toolkit as a package.
You create __init__.py in the appropriate directory and everything works... ?
