WhatsNew | Showcase new features after an app update | iOS library

I am a new to python programming and trying to understand how it works while editing a string file. I wanted to call either variables or lists or tuple in a string and solve the values and update the string file. Here is a simple example

In almost all releases of pandas there is in Documentation / Release notes the part “Fixed regressions”, where all items begin with the words “Fixed regression...”, e.g.

Fixed regression in read_excel() that caused it to raise AttributeError when checking version of older xlrd versions (GH38955)

What does in mean the term “regression” in this context?
Why fixed regressions are not included in the (next) part “Bug fixes”?

It like looks several CouchDB features are deprecated in 3.0 and will be removed in 4.0. Is this functionality gone or just moved somewhere else?

Removed functionality (per: https://docs.couchdb.org/en/latest/whatsnew/3.0.html#deprecated-feature-warnings)

Since dict object has native key order in Python 3.7+ (https://docs.python.org/3/whatsnew/3.7.html), there should be a way to manage the order. Is there an official documentation where I could read about it?

In my particular case I want to solve such issues without creating a new dictionary.

1. Add a new key-value pair to the beginning.
2. Sort the records in a dictionary by keys.

For the first one:

Python 3.9 includes PEP 585 and deprecates many of the types in the typing module in favor of the ones in collections.abc, now that they support __class_getitem__. This is the case with for example Callable. To me it would seem that typing.Callable and collections.abc.Callable should always behave similarly, but they do not.

This simple example results in an error:

In our project we have texts for multiple languages stored in our database. I want to create a helper function that includes a text in a query.

This would be useful because this include happens a lot in the application and I want have the include code in one place.

The include should use the new filtered includes from Entity Framework Core 5.

This is what I want to replace:

https://docs.microsoft.com/en-us/ef/core/what-is-new/ef-core-5.0/whatsnew#many-to-many

EF Core 5 has refined the many to many relationship, we don't need to define a Entity for the "relation table", EF Core 5 will internally automatically generated the table.

Then, how can I define the DbSet for referencing to do CRUD?

e.g.

In Python 3.9 we can use type hinting in a lowercase built-in fashion (without having to import type signatures from the typing module) as described here:

I appending a new row to an existing pandas dataframe as follows:
