ipython / ipython-in-depth Goto Github PK

I'm not finding much on how to use ipdb in the docs or vids of ipython.
Could someone please post a link or more details on how ipdb is used?

thank you

Should give a nod to the python3 people as well:

I am trying to transfer environment.yml to requirements.txt and use pip install -r requirements.txt to install all packages.. Looks like nodejs package only have 0.1 version...??

Is Nodejs we install here a python package?

C:\data\external\ipython-in-depth>git checkout origin/master -f
error: unable to create file notebooks/Notebook/What is the IPython Notebook?.ip
ynb (Invalid argument)
HEAD is now at 3a95c0c... Last minute changes.

I suspect that windows does not like ?. Would it be possible to rename the notebook?

Probably next to tab completion.

00 - Notebook Basics

first code line should read

from IPython.nbformat import current
with open('00 - Notebook Basics.ipynb') as f:
nb = current.read(f, 'json')

python 3.2
running ipython3 notebook
latest GIT pull

In order to get New cell magics to run I have to close down the notebook and restart it. Having to restart the kernel to get new cell magics to work is undesirable behavior.

Initially I run the cells then I came to new cell magics %%html.
kernel busy and stays busy.
the terminal displays no errors.
I shut down the kernel and then restart 00 - What's new in 1.0
THEN the new cell magics will work but I have to restart the kernel. I can reproduce this behavior.

Same for all new cell magics
%%html
%%latex
%%javascript

thank you

The "Overview of IPython.parallel.ipynb" notebook references the nonexistent "ipython-in-depth/exercises/figs/" folder instead of "ipython-in-depth/exercises/images/" thus causing broken image links.

Question : Error pop-up but I cannot find the path - /srv/conda/envs/notebook/lib/python3.6/site-packages/selenium/webdriver/common/.
Which path could I put "chromedriver.exe" back to solve FileNotFoundError?

Cell : Driver = webdriver.Chrome(r'C:\Users\chromedriver.exe')

Expand beyond plain python to say that !ls is not really a list :-)

• Shrink or totally remove the introductory section.
• Add figures to widget section:
  
  
  
• Fix "walls of text" in custom widget section.

The front page notebook if accessed via clicking on the Python tutorial on the jupyter try website.
I assume it has to do with the spaces in the file names in the provided path. Some have them and the links apparently work in github's markdown but not in the markdown used by jupyter. A few links in the notebook substitute the spaces in the links with %20 and then they work.

This is extra annoying if you are visiting for the first time and have no clue how to fix the links temporarily to proceed.
Also, who would put spaces into file names? This can lead to a lot of issues under some systems.

• fix file names
• fix broken links
• also there is a mistake at the end of this part of the tutorial. You want to explain how to open a terminal but write one should click on "Text File"

The file examples/Notebook/What is the IPython Notebook?.ipynb contains a character (?) which is invalid on Windows.

This leads to issues when cloning the repo or unzipping an archive:

Walking through the tut and I found this error:

Heading cells automatically get anchors with their text, so you can link to them:
