Is it safe, efficient, and reliable to pass an entire object as a value?

Yes! Everything in Python is an object.

If I'm correct, this is the print function returning an address in memory denoting the object. Does this represent any issues? ... is the print function returning an address in memory denoting the object. Does this represent any issues?

No issues here. It depends entirely on the __repr__ overrides of the class. If it doesn't have one, then the default implementation is to print out the id() of the object and its class type. E.g.

That error is caused by the fact that the number of columns has changed (by reason of your addition of the 100000000 child node to ), without adjusting the number of items in your row variable.

So if you change that variable to read:

First, the sample xml in your question (and probably your actual xml) doesn't really lend itself to read_xml(). In this case you are probably better off using an actual xml parser and handing the output over to pandas.

In addition, I don't think your desired output is very efficient - in your example, you repeat each of the long and short description 3 times, for no apparent reason.

Having said all that, I would suggest something like this:

Assuming your actual xml has more than one pet, something like:

You have a uniqe constraint over Flight, which won't work

A two part answer:

• Your back-end has no business putting files into your front-end's directory structure.

  A better choice might be to use an uploads/ folder in the back-end project, exposing those over HTTPS, and linking to them from your front-end.

• But that won't work on Heroku due to its ephemeral filesystem.

  An even better choice would be to save them to a cloud-based object store like Amazon S3 or Azure Blob Storage, or a more specialized service like Cloudinary if they're images. Heroku tends to recommend S3.

  Your back-end now just needs to store the URL to each file and provide that link to your front-end upon request.

  Even on other hosts that allow you to save files into your back-end's filesystem, using a third-party service has many benefits. You can trivially scale horizontally (adding new nodes), your application becomes less stateful, etc.

User uploads never belong in your code repository, no matter how and where you choose to host them. They are content, not code, and should not be tracked and versioned alongside your code.

So i do not see a title field on your data object. But this is how you can do it for finding exact match. The implementation is for filtering on name and equipment. If you need a partial match you can do item.name.toLowerCase().split(/\s+|./).includes(query.toLowerCase())

MDN Documentation for object.assign shows you how to copy "accessors"

Here's your code that works as expected - the completeAssign function is based entirely on the code in that link

I modified the solution, I guess this one is more straight forward:

• For Major_mercus column, I first created a customized name with paste0 by concatenating Merus_ with the value of Handedness in every row. Then I retrieve the value with get function
• For Minor_mercus I basically did the same but I used ifelse to first swap the R and L value in each row and then retrieve the desired value

Subquery returns profession wise student count and join with student and grades for retrieving final result where no_of_student per profession appears more than one.
