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 want to highlight error line when I finish running code in vscode. Just like this code I wanna highlight 45 and 57 lines. What can i do?

I'm trying to open a csv file for my python book project and this error keeps popping up
File "c:\Users\MSFT Surface Pro 3\Documents\Programming\Python\Python AIO\Code.py", line 13, in <module> birthYear = int(row[1] or 0) ValueError: invalid literal for int() with base 10: ' 1/11/2011'
and this is super annoying, help me please!
Looks like line 13 in in Code.py is birthYear = int(row[1] or 0), but probably should be something like birthYear = row[1] or "".
I'm trying to read this pdf file (https://www.accessdata.fda.gov/cdrh_docs/pdf14/K141693.pdf) and am following these suggestions from SO
Opening pdf urls with pyPdf
I have actually downloaded the file locally and am running the following code
import PyPDF2
pdf_file = open("K141693.pdf")
pdf_read = PyPDF2.PdfFileReader(pdf_file)
but my code hangs indefinitely. I'm running Python 2.7 and here is the stacktrace.

I came across another post here PyPDF2 hangs on processing but that too doesn't have a response.
You need to parse the file in binary ('rb') mode. (This works in Python 3:)
import PyPDF2
pdf_file = open("K141693.pdf", "rb")
read_pdf = PyPDF2.PdfFileReader(pdf_file)
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.
