Everytime i enter into ipython mode, ipython welcomes me with this message,

Greeting people is all good and well but it takes up most of my shell screen and i am made to do clean to remove them.
How can i disable this welcome message via configuration file?
You can use
ipython --no-banner
or set in configuration file
c.TerminalIPythonApp.display_banner = False
Just use:
ipython console
You'll get it, if that's what you want.
Editing the IPython config file
Edit your config file and add
c.TerminalIPythonApp.display_banner = False
The default profile's config file is found at /home/<user>/.ipython/profile_default/ipython_config.py
The documentation for IPython configuration can be found here
Updating default profile
Create new config file if it does not exist, or use
ipython locate profile
to view the current profile location.

When I write something in the jupyter notebook markdown field, the typos are not highlighted and often I ended up with something like this:
In almost all IDEs I have used so far, the typos are highlighted with a curly underline which was very convenient for me. Something like this:
Up till now I have not found anything that allows me to see this type of highlights. Does it exist?
The popular Jupyter Notebook bundle extension from Jupyter-contrib contains a spell checker. You can install and enable this (with admin privileges) like so:
pip install jupyter_contrib_nbextensions
jupyter contrib nbextension install --user
jupyter nbextension enable spellchecker/main
This may be the most popular spell checker for Jupyter Notebooks, but note that it simply highlights words not in its dictionary, and does not offer corrections.
If the extension installed properly, you will see this message in the command line:
Now, in the browser, after opening Jupyter, you will see the button labelled "abc" beside the keyboard button, which you can toggle to enable/disable spell check:
The jupyter-contrib library has many other useful modules such as code folding and table of contents.
Run the following in a terminal:
ipython install-nbextension https://bitbucket.org/ipre/calico/downloads/calico-spell-check-1.0.zip
ipython install-nbextension https://bitbucket.org/ipre/calico/downloads/calico-document-tools-1.0.zip
ipython install-nbextension https://bitbucket.org/ipre/calico/downloads/calico-cell-tools-1.0.zip
jupyter nbextension enable calico-spell-check
You can see typos like

Afterwards, you need to activate the spell check in the Jupyter Notebook:
%%javascript
IPython.notebook.config.update({
"load_extensions": {"calico-spell-check":true,
"calico-document-tools":true,
"calico-cell-tools":true
}
})
The spellchecker and some other extensions from jupyter_contrib_nbextensions is incompatible with the ipython version 5.8.0. and later. (Found that it works in some cases for the version 5.0.0 [refer issue page of the same]. I'm not aware of its compatibility for the ipython versions between 5.0.0. to 5.8.0., please do comment if anyone knows).
The calico's nbextension 'spellchecker' available at https://bitbucket.org/ipre/calico/downloads/calico-spell-check-1.0.zip is an outdated version [dated 2015]. But calico had updated their nbextensions and made avaliable at the github repository [latest dated 2018]. It works fine for the ipython version 5.8.0.
Installation
git clone https://github.com/Calysto/notebook-extensions.git
cd notebook-extensions
jupyter nbextension install calysto --user
jupyter nbextension enable calysto/spell-check/main
Check its status:
jupyter nbextension list
When you now open or reload a notebook, there would be a new button visible with a check mark icon next to the button to open the command palette. You may click on it to check the spelling mistakes in the markdown cell.
In the ipython qtconsole it automatically displays the documentation for a function when I type the opening parenthesis. For example, when I'm typing
plt.show()
the documentation for pyplot.show is displayed when I've typed
plt.show(
This documentation is displayed in a pop-up window that, much more often than not, blocks my view what I'm typing. Is there a configuration to stop the ipython qtconsole from doing this?
The feature to which you refer is calltips or more precisely IPythonWidget.enable_calltips and is documented at https://ipython.org/ipython-doc/dev/config/options/qtconsole.html. The only effective way I have found to disable it is by adding --IPythonWidget.enable_calltips=False as an argument to qtconsole that in turn an argument of ipython. A command line for all of this is:
ipython qtconsole --IPythonWidget.enable_calltips=False
I have verified this with IPython QTConsole 3.2.0 and believe it generally works for versions below 4, which I have not been able to install yet without breaking QTConsole. (I believe what some refer to as IPython 4 is also known as Jupyter 4. See below for information on Jupyter and disabling calltips in it.)
On Linux and Windows system, generating this command line can be automated using a bash alias. On Windows it can be automated by using it as the Target of an icon configured in its properties.
It is supposed to be possible to disable calltips by setting c.IPythonWidget.enable_calltips = False in the right configuraton file in which c = get_config() is set on the first line. I tried doing this on a Windows 7 system in ipython_qtconsole_config.py and ipython_config.py in ~.ipython\profile_default\ and several other locations, but could not get it to work.
Project Jupyter is the successor to the IPython project and began in 2014. Its website is http://jupyter.org and information about its Qt console is at http://jupyter.org/qtconsole/stable/index.html. In response to a question about disabling IPython calltips, which I submitted to https://github.com/ipython/ipython/issues, I received the following on how to disable calltips for Jupyter:
On the command line
jupyter qtconsole --JupyterWidget.enable_calltips=False
or add
c.JupyterWidget.enable_calltips = False
to
~/.jupyter/juptyer_qtconsole_config.py
I have a PuTTY terminal running emacs 23. I just installed python-mode.el-6.1.2 and pinard-Pymacs-5989046. The IPython shell looks like this:

Does this look like a charset issue in my PuTTY setup or should I try to find the issue within emacs/python-mode?
Looks like a broken ansi-color-filter
Please check if it happens also with current trunk from

Solution: add this line to ~/.emacs.d/init.el:

I am new to Linux and Python, just starting some programming this weekend. All was going great until this morning, when I was playing with "save" to save my workspace. (I selected the "magic" menu bar, so perhaps I screwed up something from there.) I must have changed my settings so that the prompt no longer appears when I start IPython. I get all the stuff that normally appears prior to getting the prompt (shown below), but no prompt and the interpreter does not work. If I run IPython in terminal, I get the prompt and all works fine. The problem is just in IPython console. I have rebooted just in case (perhaps this is a windows thing and does not apply to Linux).

I've been using the Enthought Python Distribution for about a month, and like it a lot. I test my code in ipython, which gives me the following when I launch it in a terminal :

I'm now looking for an IDE, and I've come across problems with Canopy - specifically, getting it to use my Enthought distribution as their live consoles, much like my ipython works.
I can't find anywhere to change the interpreter under Canopy. When it launches, it gives me
Welcome to Canopy's interactive data-analysis environment!
with pylab-backend set to: None
Type '?' for more information.
This isn't using EPD, and thus, isn't using any of the packages that I've got installed.
Any ideas would be fantastic !
Thanks.
This article should answer your question.
In brief, there is no way at present to change the interpreter in Canopy. However, Canopy is built on an improved version of EPD.
So you would need to re-install your packages into Canopy. However you should never need to do this again, even when Python is updated (e.g. eventually to 2.7.5) -- whereas with EPD, whenever the interpreter changed, you had to reinstall and start from scratch.
If you do install Canopy 1.0.0, be sure to update to 1.0.1 (from Help menu) before installing your other packages.
