I’m new in python and I have a concurrent problem when using internal functions of importing libraries. The problem is that my code calculates different kinds of variables and in the last process they are saved into different files. But I have the same problem when reading and writing. This is an example code that works because is linear: But
Delete empty lists from tuple from inside a list
I have a list of tuples which in turn have 2 elements and a list. I wish to delete the tuples that have empty lists. Expected output: I tried : It throws me a Memory Error Answer One way using list comprehension with unpacking: Output:
what data type is returned by re.search(pattern, stringOfText) in Python? An int or string?
Consider the following code below. I was told that if regExMagic() doesn’t find a match for Lucy in the string of text, it returns “None” to regExMagic(). Since “None” is already a string why do we still need to wrap regExMagic() in a str() in the comparison below? What’s interesting is when I removed str() it executed only the else
How can I pass in url arguments to an APIRequestFactory put request?
I have been trying for hours but cannot figure out how to pass a url argument through an APIRequestFactory put request. I have tried it through Postman when running my server and the url variable is passed just fine, but when I run it in my tests it stops working. What I mean is that when I send a Postman
Python algorithm to approximate closest parallel equivalence of resistors from a list
The formula for series equivalence of resistors: series equivalence = sum(resistors) For parallel it is 1/(sum(1/resistors[i])) I wrote code to return a list of resistors that is closest to a specified target value from a list, within a specified tolerance. So for example series_equivalance([1,2,3,4,5],7,0)will return [5,2]. I want to a function that can do the same for parallel equivalence. How
Exe generated by PyInstaller fails quietly on a different machine
I’m having trouble getting an exe generated by PyInstaller on one PC (PC-Good) working on another (PC-Bad). The exe is created on PC-Good, and executes as expected on PC-Good Both PCs are running Windows 10 Issue occurs on PC-Bad upon calling most of the matplotlib.pyplot methods (such as subplots() or plot()) Issue persists even when matplotlib is in non-interactive mode
How to groupby multiple columns with count unique value in Python Pandas
I have a DataFrame df_data: I have a function and parameter like this: Explain Parameters: with CustID = 1 the parameters should be list_minor = [3,1] (position is not important), list_major = [1] because with LocationID = 324 he get 3 times and LocationID = 490 he get 1 time (324,490 gets isMajor = 0 so it should be into
Is there a way to run GLM.from_formula without the intercept (PyMC3)?
This may be a dumb question but I’ve searched through pyMC3 docs and forums and can’t seem to find the answer. I’m trying to create a linear regression model from a dataset that I know a priori should not have an intercept. Currently my implementation looks like this: As I said, I know I shouldn’t have an intercept but I
PyOpenGL, pygame, and errors when drawing a shape
I’ve been writing a custom snake game using python, pygame, and pyopengl. I’m trying to draw a shape on the screen. However, I’ve stumbled upon this error: The console is throwing me a TypeError and an Attribute error. I’m not sure if this is due to my code or an issue with one of the libraries. I’m using Python 3.9.1,
Turning an Open CV frame into a Base64 encoded JPEG
I want to take a frame from an Open CV webcam stream, produce a JPEG thumbnail and then encode it as Base64 (It will then be sent as an MQTT message, but this is not the problem). My Python “sendimage” function is: It seems to work as far as the cv2.imencode, but the base64.b64encode fails with. Exception in thread Thread-1:
