Creating a todo list that uses the "match" function:
while True:
user_action = input("Type add, show, edit, or exit: ")
user_action = user_action.strip()
match user_action:
case "add":
todo = input("Enter a todo: ")
todos.append(todo)
file = open("todos.txt", "w")
file.writelines(todos)
Here is what happens:
Traceback (most recent call last):

I suspect that there is no "match" function in PyDroid. Sorry, but I'm quite new at this. Is there something I'm missing or some way I can make a work-around? Thanks in advance!
It seems the real problem here is that the version of PyDroid is 3.9.7, which is to say, it does not contain the "match" function.

I am trying to get the expected value of a NumPy array but I am running into a problem when I pass my array into the function here is an example of what is happening:
a = np.ones(10)
stats.rv_continuous.expect(args=a)
I get this error:
Traceback (most recent call last):
File "<pyshell#3>", line 1, in <module>
stats.rv_continuous.expect(args=a)
TypeError: expect() missing 1 required positional argument: 'self'
If I try stats.rv_continuous.expect(a) , I get this error:
'numpy.ndarray' object has no attribute '_argcheck'
Can someone tell me how to get scipy.stats to work with an array?
update:
following bob's comment I changed the code to:
st=stats.rv_continuous()
ev = st.expect(args=signal_array)
print(ev)
where signal_array is a numpy array. However I now get this error:

I have a problem with my Spark script.
I have dataframe 2, which is a single column dataframe. What I want to achieve is, returning only the results from df1 where the user is in the list.
I've tried the below, but get an error (also below)
Can anyone please advise?
listx= df2.select('user2').collect()
df_agg = df1\
.coalesce(1000)\
.filter((df1.dt == 20181029) &(df1.user.isin(listx)))\

Not sure this is the best answer but:
# two single column dfs to try replicate your example:
df1 = spark.createDataFrame([{'a': 10}])
df2 = spark.createDataFrame([{'a': 10}, {'a': 18}])
l1 = df1.select('a').collect()
# l1 = [Row(a=10)] - this is not an accepted value for the isin as it seems:
df2.select('*').where(df2.a.isin(l_x)).show() # this will throw and error
df2.select('*').where(df2.a.isin([10])).show() # this will NOT throw and error
So something like:
l2 = [item.a for item in l1]
# l2 = [10]
df2.where(F.col('a').isin(l2)).show()
(Which is a bit weird to be honest but... there is a ticket for supporting isin with single column dataframes)
Hope this helps, good luck!
edit: this is provided the collected list is a small one :)
Your example would be:
listx= [item.user2 for item in df2.select('user2').collect()]
df_agg = df1\
.coalesce(1000)\
.filter((df1.dt == 20181029) &(df1.user.isin(listx)))\
.select('list of fields')
I'm coding something which will read PDFs online and return a set of keywords that are found in the document. However I keep running into a problem with the extractText() function from the PyPDF2 package.
Here's my code to open the PDFs and read it:
x = myurl.pdf
if ".pdf" in x:
remoteFile = urlopen(Request(x, headers={"User-Agent": "Magic-Browser"})).read()
memoryFile = StringIO(remoteFile)
pdfFile = PyPDF2.PdfFileReader(memoryFile, strict=False)
num_pages = pdfFile.numPages
count = 0
text = ""
while count < num_pages:
pageObj = pdfFile.getPage(count)
count += 1
text += pageObj.extractText()
The error that I keep running into on the extractText() line goes like this:
Traceback (most recent call last):
File "errortest.py", line 30, in <module>

Would be great if someone could help me out! Thanks!
There is too little information to be certain, but PyPDF2 (and now pypdf) improved a lot in 2022. You will probably just need to upgrade to the latest version of pypdf.
If you encounter a bug in pypdf again, please open an issue: https://github.com/py-pdf/pypdf
A good bug ticket contains (1) your pypdf version (2) the code + PDF document that caused the issue.
I've been given a Python (2.7) function that takes 3 strings as arguments, and returns a list of dictionaries. Due to the nature of the project, I can't alter the function, which is quite complex, calling several other non-standard Python modules and querying a PostgreSQL database using psychopg2. I think that it's the Postgres functionality that's causing me problems.
I want to use the multiprocessing module to speed up calling the function hundreds of times. I've written a "helper" function so that I can use multiprocessing.Pool (which takes only 1 argument) with my function:
from function_script import function
def function_helper(args):
return function(*args)
And my main code looks like this:
from helper_script import function_helper
from multiprocessing import Pool
argument_a = ['a0', 'a1', ..., 'a99']
argument_b = ['b0', 'b1', ..., 'b99']
argument_c = ['c0', 'c1', ..., 'c99']
input = zip(argument_a, argument_b, argument_c)
p = Pool(4)
results = p.map(function_helper, input)
print results
What I'm expecting is a list of lists of dictionaries, however I get the following errors:

InterfaceError: connection already closed
Does anybody know what might cause the Pool function to behave like this, when it seems so simple to use in other examples that I've tried? If this isn't enough information to go on, can anyone advise me on a way of getting to the bottom of the problem (this is the first time I've worked with someone else's code)? Alternatively, are there any other ways that I could use the multiprocessing module to call the function hundreds of times?
Thanks
I think what may be happening is that your connection object is used across all workers and when 1 worker has completed all its tasks it closes the connection and meanwhile the other workers are still working and the connection is closed so when one of those workers tries to use the db it is already closed.
