How do I create a lexical dispersion plot in pyspark with seaborn?

I'm trying to make a lexical dispersion plot that maps out when words in a certain 'top ten' list are used over time through a column of strings in a Pysparks data frame (another column has their relevant dates).


I've got my dataframe at the moment with the texts, their dates, and the words used in each.


my dataframe


As it is, my plot has a row for each individual text with a list of the words in it, when what I'm after is a row for each key word, mapping the instances in which it appears in texts over time...


This is the kind of thing I'm after, vs what I'm getting...


the type of thing I'm after


how my plot is coming out


Here's a function which I use to return words from my list which are present in a given description:
import seaborn as sns
import matplotlib.pyplot as plt
import pandas as pd
from pyspark.sql.functions import split, udf

top_ten = [row['word'] for row in top_ten_words]

punctuation = ',?!./\#@"[]'

@udf
def top_ten_list(description):
'''
function to return the key words which are present in a certain description string
'''
list_of_words = description.split(" ")
out_data = []

for word in list_of_words:
word = word.lower()
if word.strip(punctuation) in top_ten:
out_data.append(word)
else:
pass

return str(out_data)




I then run that function on my column with the following:
descriptions_with_top10 = descriptions_by_date.withColumn('top_tenners', top_ten_list(descriptions_by_date.description))



Here's my code so far to make my plot. I know I need something different in the y-axis but I'm just not sure how to word it so as to get what I'm after...
# make df into pandas df to plot with seaborn
top_ten_words_in_descriptions_df = descriptions_with_top10.toPandas()

# plot dispersion plot
top_ten_plot = sns.stripplot(data = top_ten_words_in_descriptions_df, x = "published_date", y = "top_tenners", orient='h', marker='X', color='navy', size=3)

# rotate x tick labels
plt.xticks(rotation=15)

# remove borders of plot
plt.tight_layout()

plt.show()




I want it to have each word just once in the y-axis, as in this image: enter image description here, with each keyword just once, with all its occurrences marked, rather than the list of keywords for each description string.


I hope that makes some sense to someone; any help would be very welcome :)

oracle developer_ importing different forms of date in one column

I am trying to import the date columns with different types of date format. table name: fD column name: TRANS_DATE_TRANS_TIME this column has two forms of the date like below. date type1: 'MM/DD/YYYY HH24:MI' date type2: 'YYYY-MM-DD HH24:MI:SS' not surprisingly, SQL developer(oracle) cannot import this column as a DATE type. I aim to unify these forms as 'MM/DD/YYYY HH24:MI.' What I did was I import it as a VARCHAR2 type and try to write very complicate and difficult(?) query... and then I read someone wrote here that do not import date type data as a VARCHAR2 because of this. Then, is there any idea that I can import this column successfully? or I need to import it as a VARCHAR2 type and write down complicate query? (and I do not know this query either.. haha) this is what I did when I imported it as a VARCHAR2. ''' with DT as( select TRANS_DATE_TRANS_TIME from fD ) select TRANS_DATE_TRANS_TIME, replace(to_char(to_date(TRANS_DATE_TRANS_TIME, case when regexp_like(TRANS_DATE_TRANS_TIME,'[0-9]{1}/[0-9]{1}/[0-9]{4} [0-9]{1}:[0-9]{2}') then 'MM/DD/YYYY HH24:MI' when regexp_like(TRANS_DATE_TRANS_TIME,'[0-9]{2}/[0-9]{1}/[0-9]{4} [0-9]{1}:[0-9]{2}') then 'MM/DD/YYYY HH24:MI' when regexp_like(TRANS_DATE_TRANS_TIME,'[0-9]{1}/[0-9]{2}/[0-9]{4} [0-9]{1}:[0-9]{2}') then 'MM/DD/YYYY HH24:MI' when regexp_like(TRANS_DATE_TRANS_TIME,'[0-9]{1}/[0-9]{1}/[0-9]{4} [0-9]{2}:[0-9]{2}') then 'MM/DD/YYYY HH24:MI' when regexp_like(TRANS_DATE_TRANS_TIME,'[0-9]{2}/[0-9]{2}/[0-9]{4} [0-9]{1}:[0-9]{2}') then 'MM/DD/YYYY HH24:MI' when regexp_like(TRANS_DATE_TRANS_TIME,'[0-9]{1}/[0-9]{2}/[0-9]{4} [0-9]{2}:[0-9]{2}') then 'MM/DD/YYYY HH24:MI' when regexp_like(TRANS_DATE_TRANS_TIME,'[0-9]{2}/[0-9]{1}/[0-9]{4} [0-9]{2}:[0-9]{2}') then 'MM/DD/YYYY HH24:MI' when regexp_like(TRANS_DATE_TRANS_TIME,'[0-9]{2}/[0-9]{2}/[0-9]{4} [0-9]{2}:[0-9]{2}') then 'MM/DD/YYYY HH24:MI' when regexp_like(TRANS_DATE_TRANS_TIME,'[0-9]{4}-[0-9]{2}-[0-9]{2} [0-9]{2}:[0-9]{2}:[0-9]{2}') then 'MM/DD/yyyy HH24:MI' end), 'MM/DD/yyyy HH24:MI'),'') as newT from DT; '''

Livewire (+Filament) & debugging

I've worked with different frameworks quite a bit, recently mostly Laravel. There are many things I love about Laravel and quite a few pet peeves. Recently adopted Filament and I love the power, hate the lack of documentation (especially lacking source code documentation almost entirely). Filament is speeding up many things while radically slowing other things, especially when learning it. I've used Livewire in the past and love it. With Filament, everything is built on top of Livewire which has its benefits and at least one downside: debugging has become increasingly difficult. Your stack trace has 100 lines and it's very hard to understand what's going wrong. How are you approaching this aspect of debugging / development with Livewire? submitted by /u/lionmeetsviking [link] [comments]

How to rebuild a graph on an html page based on the result of selecting data in the wtform form in a flash application?

I am developing a web application in flash. The application has a database. When the user visits the page, he should see a graph with default data for the first device.

Optional Dependency in VBA Module

Background I am developing a VBA module (call it "Greg") for VBA developers of Excel UDFs. The purpose of Greg is to enhance the experience for the end user, who uses those UDFs in Excel. The developer must simply copy a snippet into their own module (call it "Dev"). If Greg is loaded, the snippet enhances Dev's behavior. Otherwise, it has no impact on behavior, but it does prompt the Excel user to import Greg.bas. Approach Here is a simplified sketch of Greg.bas... Attribute VB_Name = "Greg" ' Keep these functions invisible to Excel users. Option Private Module ' Enhancement function. Public Function Enhancer(Optional x) ' ... End Function ' Assert the 'Greg' module is loaded. Public Function IsLoaded() As Boolean IsLoaded = True End Function ...and of Dev.bas: Attribute VB_Name = "Dev" ' Some UDF by the dev. Public Function DevRegular() ' ... End Function ' ############# ' ## Snippet ## ' ############# ' Use the enhancer, if available via the 'Greg' module. Public Function DevEnhanced(Optional x) If Enhance_IsSupported() Then DevEnhanced = Greg.Enhancer(x) Else DevEnhanced = DevRegular() ' Prompt the user to import the enhancer. MsgBox "Import the 'Greg' module to enhance your experience." End If End Function ' Check if enhancement is supported via the 'Greg' module. Private Function Enhance_IsSupported() As Boolean On Error GoTo Fail Enhance_IsSupported = Greg.IsLoaded() Exit Function Fail: Enhance_IsSupported = False End Function Problem While this has worked sporadically on Windows, it has often failed there and always on Mac. The crux seems to be Enhance_IsSupported() within Dev: Private Function Enhance_IsSupported() As Boolean On Error GoTo Fail Enhance_IsSupported = Greg.IsLoaded() Exit Function Fail: Enhance_IsSupported = False End Function I assumed that the line Greg.IsLoaded() would compile, even if there were no Greg module present...and it does! It only fails when a Greg module exists without a member called IsLoaded(). Unfortunately, it seems that VBA does not reliably refresh its "awareness" of a Greg module with an IsLoaded() function. When I import Greg.bas and Dev.bas together, everything works as intended: Enhance_IsSupported() returns True, and it updates to False if Greg is removed. But when I first import Dev.bas and run DevEnhanced(), and only afterwards import Greg.bas, then Enhance_IsSupported() apparently returns False despite the presence of Greg. Note This latter workflow is absolutely essential: an Excel user must first run DevEnhanced() and see the prompt, in order to know about Greg.bas in the first place! Failed Solutions Unfortunately, no experimentation has availed. In Greg itself, I have tried using a constant... Public Const IS_LOADED As Boolean = True ...and also a procedure: Public Function IsLoaded() As Boolean IsLoaded = True End Function In the snippet for Dev, I have implicitly tried Application.Evaluate()... Private Function Enhance_IsSupported() As Boolean On Error GoTo Fail Enhance_IsSupported = [Greg.IsLoaded()] ' ^^^^^^^^^^^^^^^^^ ' Application.Evaluate("Greg.IsLoaded()") Exit Function Fail: Enhance_IsSupported = False End Function ...but while this works for Enhance_IsSupported() itself, the same error simply crops up elsewhere — like whack-a-mole at other instances of Greg.* — and only a manual edit will "refresh" those procedures. I would also prefer to avoid unstable calls to any .Evaluate() method, even in the Worksheet scope. Questions * What is the simplest way to "refresh" the Dev module, such that its procedures now recognize the calls to Greg.*? * Is this possible without resetting cached or Static variables in Dev? * Can this be done with an IS_LOADED constant rather than an IsLoaded() procedure? Bonus * Can this refreshment be done by some Sub like Dev.Refresh(), called automatically at the start of Enhance_IsSupported()? * Can this refreshment be done by some Sub like Greg.Refresh(), as run manually by the user in the VBA editor? --- This project represents a great investment of my time and energy, and it is otherwise operational, so your help is greatly appreciated in conquering this final obstacle!

Some AWS lamba execution have more than 1 S3event key

I'm having an issue when passing events to the AWS lambda function. I have to sync 60k data in 1 json file to a remote server. My solution is to divide the file into many small files (2000 data/ file) since the function cannot process 60k data in 15 minutes. After breaking the files, I will upload them one by one to S3 (time interval is 10 seconds), when a new file is uploaded, it will send a S3Event notification to trigger the function, and that function execution will take the newest uploaded file to process. The speed is impressive, but when the number of data reaches 60k, it does not stop, it continues adding more 4k items (I don't know where it came from). When I check the newest CloudWatch log, it seems there are some executions that have more than 1 S3Events like below "Records": [ { "eventVersion": "2.1", "eventSource": "aws:s3", "awsRegion": "ap-southeast-1", "eventTime": "2023-09-08T06:26:38.873Z", "eventName": "ObjectCreated:Put", "userIdentity": { "principalId": "AWS:AIDA4EODLYGLIMIHEIAVB" }, "object": { "key": "test_4.json", "size": 846900, "eTag": "44768b0689b2acd120c7683d8f0ce236", "sequencer": "0064FABE9E323A01CD" } } } ] "Records": [ { "eventVersion": "2.1", "eventSource": "aws:s3", "awsRegion": "ap-southeast-1", "eventTime": "2023-09-08T06:28:06.642Z", "eventName": "ObjectCreated:Put", "userIdentity": { "principalId": "AWS:AIDA4EODLYGLIMIHEIAVB" }, "object": { "key": "test_12.json", "size": 845141, "eTag": "05008d0d12413f98c3aefa101bbbd5eb", "sequencer": "0064FABEF5B003C033" } } } ] This is so weird, This is the 1st time I have worked with AWS so can someone help me explain the reason? Also, Is it possible to make all execution run synchronously instead of asynchronously? I think if they are running in order, it will be easily to debug then.

LINQ Query returning an empty result

I am fairly new to LINQ and am having problems with a query. var LoadDetentionTypes = _db.Settings_DetentionTypes .Where(f => SchoolAreaList.Any(s => f.SchoolArea.Equals(s))) .Select(i => new { i.DetailsforDetentionToShow, i.DetentionTypeDescription, i.DetentionTypeCode }); SchoolAreaList is an array and holds say for example two values: BMS and BSS f.SchoolArea is a column in the database and can hold values in the format ["BMS", "BSS"] I am trying to do a query that will check if any of the values in the array are in the database and if there is a match it selects the record. The problem is that this query continually returns an empty result. Before using Equals, I used Contains, but I received an error. Am I trying to do too much in a single line and should I break it up with a ForEach on the array and add to a list? Any help would be much appreciated. Regards, Darren
