问题 I've followed several examples to create and drop a DB2 table using SQLAlchemy within a python jupyter notebook. That works fine. But after creating the table, I need to set privileges so others can view it. I use this code to create a new table from a Pandas dataframe "df" from sqlalchemy import create_engine, text engine = create_engine(r"...") df.to_sql(name='MYTABLE', schema='MYSCHEMA', con=engine, if_exists='replace', dtype=dashdb_typemap, index=False) I can drop the table just fine with

问题 So I was browsing through YouTube and found that it's possible to show all possible methods. For instance, I read you could use TAB or Shift+Tab but I still cannot get it to work. I have the latest Python downloaded. How can I make this option available? 回答1: You have to first initialize te object. Ex: execute a=[] in a cell, then type a.TAB and jupyter will show you all possible methods for a list. (similar for all other objects) Example for a list: Example for a Dataframe: 来源： https:/

问题 I use the package remote_ikernel to automatically connect to an azure VM from an azure VM. The two systems are identical, that is, they have the same python environments. I start a remote kernel using ssh -oStrictHostKeyChecking=no {username}@{ip} sudo /anaconda/envs/py36/bin/ipython kernel And then update my local kernel.json by filling the parameters in the script below. {{ "argv": [ "/anaconda/envs/py35/bin/python", "-m", "remote_ikernel", "--interface", "ssh", "--host", "{username}@{ip}",

问题 I have a website that performs file format conversions, and this service can be used by other websites via the window.postMessage system. It would be great if one could do this also via a Jupyter notebook. I run however into a serious issue. I can get python to create a Javascript command that sends a file in format A to the website, and I can access the response (file in format B) in Javascript after some delay, but I cannot get the response from Javascript back into Python for further

However it uses temporary folder as ${fileDirname} instead of original file folder. Same issue was discussed couple times already (e.g. https://stackoverflow.com/a/54794976/12488601) with tried solution pointed out. Here is example of cwd: os.getcwd() .. 'C:\\Users\\MjH\\AppData\\Local\\Temp\\1f6cc207-562f-4ae1-8754

问题 I am using ipython widgets in my jupyter notebook. Now when kernel is restarted, the widget state is lost and a message is displayed: “Jupyter widget could not be displayed because the widget state could not be found. This could happen if the kernel storing the widget is no longer available, or if the widget state was not saved in the notebook. You may be able to create the widget by running the appropriate cells” So when a user reopens his notebook after a kernel restart, he doesn't find the
