re.DOTALL enabled all the time?
by David Rock March 10, 2025

March 10, 2025

I was trying to help someone understand matching across newlines with . and came across something strange. Best I can tell, it looks like re.DOTALL is always active. >>> mytext = r'ab<c. de fg<hMOD3876Xi\nj>klmnop\nqr. st>uvwxyz' >>> mytext 'ab<c. de fg<hMOD3876Xi\\nj>klmnop\\nqr. st>uvwxyz' >>> print(mytext) ab<c. de fg<hMOD3876Xi\nj>klmnop\nqr. st>uvwxyz >>> import re >>> match = re.search('<.*?>',mytext) >>> match <re.Match object; span=(2, 26), match='<c. de fg<hMOD3876Xi\\nj>'> I would have expected this to fail to match because a . should not match a newline and never find seriously > A few questions: if re.DOTALL is baked in somehow, how do you disable it? Setting re.NOFLAG doesn't do it is there a way to see what flags were used in a match/search? when did this behavior change? -- David Rock david(a)graniteweb.com

Help Needed with Extracting Data from PDF to Excel in Matillion
by Basnuevo, Carlos March 7, 2025

March 7, 2025

Hello, I’ve hit a roadblock and could really use some help. I’m working on creating a script in Matillion to extract data from a PDF and insert it into Excel. However, my challenge is that I need to retain the same structure from the PDF in the Excel sheet—this includes the columns, headings, and spacing. I’ve attached both the script I’ve been working on and a sample PDF. Despite my efforts, I’m unable to maintain the layout correctly in the Excel output. I would really appreciate any guidance or suggestions on how to resolve this issue. Looking forward to your feedback! *Carlos Basnuevo* Audience Systems Analyst Administration 305-376-3326 cbasnuevo(a)miamiherald.com mcclatchy.com <https://mcclatchy.com/>

How to properly use py-webrtcvad?
by marc nicole Jan. 22, 2025

Jan. 22, 2025

Hi, I am getting audio from my mic using PyAudio as follows: self.stream = audio.open(format=self.FORMAT, > channels=self.CHANNELS, > rate=self.RATE, > input=True, > frames_per_buffer=self.FRAMES_PER_BUFFER, > input_device_index=1) then reading data as follows: for i in range(0, int(self.RATE / self.FRAMES_PER_BUFFER * > self.RECORD_SECONDS)): > data = self.stream.read(4800) on the other hand I am using py-webrtcvad as follows: self.vad = webrtcvad.Vad() and want to use *is_speech*() using audio data from PyAudio. But getting the error: return _webrtcvad.process(self._vad, sample_rate, buf, length) > Error: Error while processing frame no matter how I changed the input data format (wav: using speech_recognition's *get_wav_data*(), using numpy...) Any suggestions (using Python 2.x)? Thanks.

How to weight terms based on semantic importance
by marc nicole Jan. 15, 2025

Jan. 15, 2025

Hello, I want to weight terms of a large text based on their semantics (not on their frequency (TF-IDF)). Is there a way to do that using NLTK or other means? through a vectorizer? For example: a certain term weights more than others etc... Thanks

Re: [Tutor] How to go about describing my software with a component diagram?
by marc nicole Dec. 26, 2024

Dec. 26, 2024

I want to convey the idea that main.py (main algorithm) imports 3 modules (V, S, M) (each of them containing .py scripts related to different functionalities) and use their methods accordingly as per the requirement: basically the structure of my code and how the modules relate to each other.
