QUESTION
I have some columns titles essay 0-9, I want to iterate over them count the words and then make a new column with the number of words. so essay0 will get a column essay0_num with 5 if that is how many words it has in it.
so far i got cupid <- cupid %>% mutate(essay9_num = sapply(strsplit(essay9, " "), length))
to count the words and add a column but i don't want to do it one by one for all 10.
i tried a for loop:

I want to reuse same class more than once in a chain of decorated objects like this.
InstrumentedTargetDecorator -> ResilientTargetDecorator -> InstrumetedTargetDecorator -> Target
Note that InstrumentedTargetDecorator is used twice here on purpose.

ANSWER
Answered 2022-Jan-29 at 16:13You encountered a bug in Simple Injector. I will try to fix this in the next patch release. This bug has been fixed in v5.3.3.
As workaround, when working in an older release, create a derivative of the decorator inside your Composition Root and make that derivative the second registration. Hopefully this suppresses the invalid warning:
QUESTION
I am struggling with using facet_grid() and facet wrap() with ggplot(). I would like to be able to wrap the different stacked barcharts for every two categories (of the variable Department here) but at the same time have the same width of bars. The first action can be achieved with facet wrap() while the second one can be achieved with facet_grid(). I would like to combine the advantages of both functions. Do you have any idea on how to solve the problem please?
The data is:
...ANSWER
Answered 2022-Jan-23 at 17:35Is the following acceptable?
I get this by removing scales = "free" from facet_wrap(). The columns are the same width. You may prefer to not have the open space where one gender does have any data for the department. However, I think this is easier to read as the category axis labels are in the same place on each plot (Female on left and Male on right) and this plot clearly conveys that there are some departments where Female or Male customers make no purchases.
Here is the code:

QUESTION
I got this code to almost work, despite much ignorance. Please help on the home run!
- Problem 1: INPUT:
I have a long list of URLs (1000+) to read from and they are in a single column in .csv. I would prefer to read from that file than to paste them into code, like below.
- Problem 2: OUTPUT:
The source files actually have 3 drivers and 3 challenges each. In a separate python file, the below code finds, prints and saves all 3, but not when I'm using this dataframe below (see below - it only saves 2).
- Problem 3: OUTPUT:
I want the output (both files) to have URLs in column 0, and then drivers (or challenges) in the following columns. But what I've written here (probably the 'drop') makes them not only drop one row but also move across 2 columns.
At the end I'm showing both the inputs and the current & desired output. Sorry for the long question. I'll be very grateful for any help!
...ANSWER
Answered 2021-Nov-27 at 21:36Store your data in a list of dicts, create a data frame from it. Split the list of drivers / challenges into single columns and concat it to the final data frame.

QUESTION
Since onSaveInstanceState & onRestoreInstanceState can't be used to store/restore values after closed the app, I tried to use dataStore to solve it, but it dosen't work, here's my trying
DataStoreRepository
ANSWER
Answered 2021-Oct-20 at 10:33As the SharedPreference will be deprecated soon or later, there is an Update below using DataStore.
SharedPreference
onSaveInstanceState & onRestoreInstanceState can't be used to store/restore values after the app is closed/shut.
Even if the app is not closed, you can't rely on them for storing large objects or storing objects for a long time.
Instead of that you can use SharedPreference to store a value that maps to last open fragment before the app exists.
Here I store some arbitrary value, as it's recommended not to store application IDs, as they can vary from app launch to another. So, you can store arbitrary values and map them to the generated IDs in the current app launch.
I picked those values as array indices:
QUESTION
I am practicing my layout but I'm facing a problem with my layout. I'm a beginner with flex and grid CSS. As you can see in the picture the horizontal scrollbar shows when the screen width is 1440 or above. I don't want to show that. I also tried the overflow-x: hidden but it always shows. How can I fix that? Thanks so much!
This is my code:
...ANSWER
Answered 2021-Oct-14 at 14:53Hiding overflow isn't usually a solution--it just masks problems. The best approach in cases like this is often to start removing widths from things. You're forcing some that don't help.
Here, set the left value of your navbar so it's in frame. You may need to add padding to move the logo and button over.
Then, remove the width rule from the main container element.
