kandi X-RAY | karel Summary
Karel is a pretty snazzy environment for learning to program. You can read about it here. I decided to write a Karel environment for Python, after seeing that all of the others had too many dependencies for beginners. Stephen Altamirano (alts/karel).

QUESTION
I'm getting 'ValueError: Length of values does not match length of index' while using Pandas. I'm reading in data from an Excel spreadsheet using Pandas' 'pd.read_excel method. I then filter the data using Pandas' filter method. I've created 'dataSubset' to represent the filtered data. I use 'dataSubset' to create several 'mean' columns representing the mean of multiple columns respectively. I then create 'finalData' which represents the pd.concat function concatenating all of the calculated mean columns together. This code runs perfectly; however, if I uncomment any additional columns, the code blows up and gives the aformentioned error.
What am I doing wrong? It works as long as I don't concatenate more than it wants.
Help.

QUESTION
As mentioned above, I'm trying to get the mean of several columns then concatenate the resulting dataframes into a new dataframe. I'm getting the following error:
FutureWarning: Dropping of nuisance columns in DataFrame reductions (with 'numeric_only=None') is deprecated; in a future version this will raise TypeError. Select only valid columns before calling the reduction. summaryData['aver_51'] = summaryData[["5.1.2 Hello World Quiz",
Here is the code:
...ANSWER
Answered 2022-Feb-02 at 01:14"Nuisance columns" are actually just columns that pandas can't process in the current operation (e.g., strings); in this case, mean. You'll have to get rid of all the columns/cells that contain strings before you can compute the mean.
QUESTION
Good day,
The "SELECT" below shows the number of employees and their arrival and departure times.
In this data, I need to find out the total number of employees (COUNT) at each time (I do not need to deal with seconds). How many people worked at the same time in a given period of time.
Example:
...ANSWER
Answered 2021-Nov-01 at 08:52Your question is more likely to be answered if you
- specify your db vendor (instead of unnecessary
select
tag) - provide minimalistic example (no underlying tables or unrelated where conditions)
- provide db fiddle
- bonus: anonymize sensitive data
To answer itself:
You should first improve representation of times since string "HH:mm" format does not give a clue how to sort 01:30 after 23:30. Probably you want datetime type truncated or rounded to minutes. Let's name it
cas_od
,cas_do
like in your code snippet.Then define ordered set of all ranges:

I have node 14.13.0, and even with --harmony-top-level-await, top level await is not working.
...ANSWER
Answered 2020-Nov-26 at 08:11Top-level await
only works with ESM modules (JavaScript's own module format), not with Node.js's default CommonJS modules. From your stack trace, you're using CommonJS modules.
You need to put "type": "module"
in package.json
or use .mjs
as the file extension (I recommend using the setting).
For instance, with this package.json

QUESTION
I just started learning how to program in Java a month ago. I am trying to make my robot (karel) put a beeper the amount of times that is indicated in the "put" integer only, not the total amount the object has. However, it is not a set number and karel.putBeeper(put);
does not get accepted in the compiler due to the class not being applied to given types. Any help would be greatly appreciated, and I am starting to understand why Stack Overflow is a programmer's best friend lol. Note: I might not respond to to any helpful tips until tomorrow.

QUESTION
I would like to automate my deployment. So far, I've been manualy publishing my Net Core 3.1 solution through Visual Studio 2019 with no problems. Hovewer, when I want to use Azure DevOps Pipeline, even though I received no errors, I always end up with hundreds of .dll files instead of one .exe file.
This is my Visual Studio configuration that works as intended:

QUESTION
Service requests performed by a service currently trigger "notifications" that components listen to using addObserver pattern ie the aService just toggles its _property and components act on it using aService.addObserver('_property'){action...}. How can I redesign this pattern in Octane, please? Thank you. Karel
...ANSWER
Answered 2020-Jul-24 at 09:27For situations like these, I find it's useful to use Ember.Evented and the pub/sub pattern.
The components use dependency injection to receive an instance of the service and in their constructor (or elsewhere if needed), they subscribe to some "topic" on the service. Consider an example where a publisher
service generates ticks at a consistent interval. In our component, we want to subscribe to the updateTick
topic and increment our current tick
value each time the event is triggered.
QUESTION
This is the code that I tried.
...ANSWER
Answered 2020-Jul-18 at 11:26The problem with that code is that facingWest()
and facingEast()
don't seem to be functions. Instead, they're properties, so use facingEast
and facingWest
(i.e. use them without brackets). That gets rid of the error but facingEast
and facingWest
are never true based on my testing, which means you can't make it turn based on that.
So, I think you'll have to write some code that doesn't rely on the facing
commands. As long as you can assume that Karel starts at the bottom left of a grid, you can just turn when the front is blocked, starting left and then alternating to right. Something like this should work, you'll just have to edit this to make sure it doesn't tell you front is blocked at the end of traversing an even-numbered grid.
