ipython

问题 Edit : The issue has been reported in GitHub. I'm leaving the question here in case it helps other people find the issue (I was not able to). I often use the _ variable for convenience when working in a Jupyter notebook (it returns the output of the latest code execution). However, when _ is used to as a placeholder for an unused variable (a typical use case in Python), it breaks the first use case. Note that this works as expected in an IPython console. Below, _ again holds the latest

问题 I have added the setting below in vscode to launch ipython when i used shift+enter to run selection. "python.terminal.launchArgs": [ "-c", "\"from IPython import start_ipython; start_ipython()\"" ] Now when i run a selection, the code will not execute in the terminal immediately, i need to navigate to the terminal and hit enter until it does. This problem doesn't occur if i just use the basic python terminal to execute single lines. Is there a setting to fix this so the snippet runs

问题 I'm trying to run Jupyter notebooks with a globally installed version of Jupyter from within virtual environments (using virtualenvwrapper , because I want to manage versions of installed packages). And I do not what to use Anaconda. The problem is when I run jupyter notebook from within the virtualenv, it cannot find the packages installed in the env, it only finds the packages installed globally. How do I set up Jupyter to check for packages installed within the virtual environment instead

问题 The following code does print 'I want this to print' in 'ipython qtconsole', however it does not print in plain IPython. import logging import logging.handlers log = logging.getLogger() f = logging.Formatter("%(asctime)s - %(module)s. %(funcName)s - %(levelname)s - %(message)s") fh = logging.handlers.TimedRotatingFileHandler('log.txt', 'W6') fh.setFormatter(f) log.addHandler(fh) log.setLevel(logging.INFO) log.info('I want this to print') In 'IPython qtconsole' however i get different problems

问题 In jupyter notebook , I can configure an automatic cell timing with nbextensions, the result is like so: How can i do this in jupyter lab ? I didn't found any extensions that did a similar thing. Obs.: I know that a similar result can be achieved with %%time magic, but i want it to be automatic, so I don't have to place the magic function at the begining of each cell 回答1: Requirement JupyterLab >= 2.0.2 Let's move step by step Extension availabel in jupyter lab is jupyterlab-execute-time

问题 How do I execute a shell command from Ipython/Jupyter notebook passing the value of a python string variable as a string in the bash argument like in this example: sp_name = 'littleGuy' #the variable sp_details = !az ad app list --filter "DisplayName eq '$sp_name'" #the shell command I've tried using $sp_name alone, ${sp_name} , {sp_name} etc as outlined in this related question, but none have worked. The kicker here is the variable name needs to be quoted as a string in the shell command.
