As the title suggests, I'm looking to find the run time for my entire Jupyter notebook.
Perhaps something like %%time for the entire notebook. Have tried looking around for a solution, but I can't seem to find one that doesn't require me to define a function.
Any help would be appreciated, thank you guys!
You can install and enable the Execute Time extension mentioned under section entitled '4. ExecuteTime: show when and how long cells ran', here. In the metadata, is the start_time and end_time for each cell, see here. You can use the start time for the first cell and the end_time for the last cell to give you the total time.
Alternatively, you can use an external call to run the notebook from another notebook and use %%time in that. For example to run the index.ipynb notebook, in a new notebook execute:
%%time
%run index.ipynb
You could use jupytext, papermill, or nbconvert to run the notebook instead of %run if you didn't want output displaying in your timing notebook. (I imagine the time to show that output might contribute and could matter in case of somethings you wish to time?) There is an example of using nbconvert and using the -t flag with the call to scripted version of the notebook to time it here.
Or you could use IPython to call to run the notebook and time this if you didn't want to use an actual separate Jupyter notebook since the %%time magic is inherited from IPython.

I was trying to using !date to print date-related information in jupyter notebook, but it seems that it just hang around there without running, what might be reason. I am using Anaconda virtual environment on windows.
In IPython syntax, the exclamation mark (!) allows users to run shell commands from inside a Jupyter Notebook code cell.
If you are on Windows, date will show the system data and allows you to set a new one. This doesn't make much sense from inside Jupyter Notebooks.
If you want to see the current date and time in IPython, instead use
import time
time.strftime("%c")
I am trying to test the speed of a cell's execution using "%%timeit" but it is not working as expected. All it ever prints is "`not found".
What's going on?

Is it possible to evaluate code in a jupyter notebook only within a certain section? Can you place a stopping point in the notebook, for example? Or delimit a section by headers?
I'm want have autocomplete in jupyter notebook. I want the feacture give by the

When I use the following code
import nltk
nltk.download() # Download text data sets, including stop words
Kernel goes in the busy state and then I am unable to execute any cells further.
When you run nltk.download(), it launches an interactive GUI window that you can use to download resources. But very often this window is hidden behind other windows on your screen. Look for it, download anything you need and then close the downloader window in order for your script to return control to the notebook kernel.
To avoid hanging when your code gets to a download command, you could use a non-interactive download command instead. E.g., nltk.download("brown") for the Brown corpus, or nltk.download("book") to get all resources needed when reading through the nltk book. These carry out the download (even if you already have the requested resource) without opening a GUI window. For this you'll need to know, or guess, the internal name of the resource you want.
