I am practicing pandas and I have an exercise with which I have a problem

I have an excel file that has a column where two types of urls are stored.

I am going through "Haskell Programming from first principles" and found an exercise asking if the following [code slightly edited here] was valid:

I'm trying to get some Morph Based Vertex animations going, but I'm getting #342 errors telling me that:

I have an app being hosted on Heroku on a single dyno with 1GB of RAM. I'm observing odd behavior with regard to memory. When my app is being used, I notice the total memory consumed on the dyno continuing to go up with load/usage (which screams memory leak but see later...) but never comes back down when garbage collection runs. I can see in my JVM graphs that heap space is regularly being reclaimed by the JVM but I never see corresponding reductions in total memory usage; it only ever seems to increase.

See the graphs below:

I have profiled a heap dump using Eclipse MAT and did not find anything telling. Also, I have added parameters to the JVM as described here to bound the JVMs target memory consumption to the container and not the server itself.

If anyone can point me in the right direction as to why there is inconsistency between the dyno memory reported by Heroku and what I'm seeing on the heap and non-heap space graphs for the JVM it would be greatly appreciated.

When I cleared the value in the InputNumber control by pressing the delete button and then press the tab button, the value remains unchanged and is not updated.

The property I bind the InputNumber control is as follows

Why, for the following snippet, the compiler screams at me saying

Not all code paths return a value

I have a dictionary with films and values called a:

I am trying to write a python-script to work with dataframes imported from excel table and another one from another source. In order to read excel file into a pandas dataframe i selected "openpyxl" as a preferred engine, however PyCharm claims there is no such module - even though I have earlier installed it.

I am working on conda and i tried to install it both using pycharm terminal and my macbook terminal: when i retype "conda install openpyxl" it returns me

By "controls" I suppose I mean a couple of things.

Basically I struggled a bit early on in the java application for my Case Study working with Eclipse to configure everything properly get it to be error free and then run, and finally I got it working through some POM settings and maven>updating project and didn't have any more issues. Then I downloaded our whole cohort's case studies and I got a lot of similar errors (red Xs in Eclipse) in most of the projects, and it seems like if I go through them one by one and configure version, among other things, they work.

So my understanding of Java/Eclipse errors and their relation to Maven and JRE version is kind of fuzzy but this is my working model (which may be wrong in some parts):

Each version of Java adds new features (obviously), and Java 1.8 was a major milestone but for the most part, for most of these projects, it seems you can pick and choose whatever version you like, as long as you configure your project settings properly. It's dealer's choice basically (?). If you compile in the command line, these things may not apply or may be passed as args.

But to configure your project properly, I guess you can go into build path and do it that way (?), but the preferred way is to have maven handle the dependencies, including the core Java Runtime library dependency (the language version itself) and you do that by setting a property in the pom.xml (which may or may not be present. Which is optional but I think recommended). Then (when you maven>"update project"), it syncs and overwrites what is the default, and it it is the system or IDE default that is causing the intial conflict. (?). Do I understand this correctly?

And maven/Eclipse knows to respect maven more than the build path or it replaces the build path, because it understands that it wants an all-in-one source of configuration truth?

And having the wrong version of java specified, even if it's closely related versions like 11 and 13, can make it seem like you have tons of errors in your code. It can't even find the common classes like String, because they are technically different, because that's just the way Java configured it, unlike perhaps other languages.

When you import a project into your IDE (e.g. Eclipse), you are given by Eclipse a default JRE version based on your IDE settings or what you downloaded, or something, but the project may expect a different version (why or wherefore, I am not sure but this seems to be the case and what throws errors or makes Eclipse throw errors). Yet if I update the maven project by right clicking, it doesn't necessarily fix the issues. My understanding is because the pom file is not complete enough, with missing properties that should ideally be there, for this very reason: e.g. source, target and release

I had a project that threw erorrs that seemed to go away when I changed
