One possibility with axvline: import pandas as pd import numpy as np import matplotlib.pyplot as plt df = pd.DataFrame(np.random.rand(9, 4), columns=['a', 'b', 'c', 'd']) df.plot.bar() plt....
Besides what Olin already said, I guess too many people were taught C using K&R book, which was great at the time, but it completely neglects modern SW engineering best practices (encapsulation...
Create a hash map and precalculate the sort key in it: // Set up: Create mock input let u = ['4', '16', '8', '2', '6']; function expensive_key_fn(x) { console.log("Doing expensive operation...
There is no infinite loop. If the dictionary is a string, it is simply skipped. If all dictionaries are strings, than all elements of the finite list are skipped, and the function returns without...
The quick fix is: map (subtract 1) . take n $ l When I put your function in my own Haskell compiler, I get: Possible cause: ‘take’ is applied to too many arguments Remember that in Haskell,...
Temporary notice: this is part of an ongoing project of transferring and splitting my canonical from Stack Overflow on common errors in Google Apps Script. As soon as the Q&As are finalized, ...
I have a function that loads JSON data and is declared to return a dictionary with string keys and values of any type (Dict[str, Any]). However, mypy is raising an error stating that I am returning...
As this is the first question about Google Apps Script, here is a very brief description: it is a platform that helps people easily get programmatic access to Google apps data like Gmail messages, ...
There are some reasons why a function would intentionally not be declared static. (In the following I use the term 'module', but in contrast to others, I use it not to describe a file or translati...
Context I noticed that an application was flooding the database with simple SELECTs. The investigation revealed some bugs in the health check which theoretically implemented caching (to avoid quer...
Hello everyone, I am seeking help with understanding why multithreading does not work correctly in this example: import time import matplotlib.pyplot as plt import concurrent.futures voltage...
private readonly int _checkInterval; What are the units? I have to search for usages to find out. I strongly favour using TimeSpan instead of int. private static readonly SemaphoreS...
Context I am currently migrating a Web application from on-prem infrastructure to K8s. The legacy infrastructure relies on defining some tokens in the configuration files and these are replaced d...
I'm trying to do some DOM manipulation in jQuery, but am having issues with creating wrapper elements. For some reason, prepending to the wrapper doesn't work after I call wrap. Code <html>...
This answer will use Python 3 for code examples. I encourage people to post other answers for other languages. I'll continue to update this answer, as I'm able, based on comments with tested/verifi...
Assuming that there are no alignment problems between the two pointer types (impl-defined), the code is otherwise well-defined. As per the quoted 6.3.2.3 C allows pretty much any form of wild and c...
Problem How can I compress each column of a dataframe to the output of a function (i.e., mean), preserving columns? MWE import pandas as pd data = {"A": [1, 2, 3, 4], "B": [5, 6, 7, 8]} ...
Let's analyze this code, assuming an architecture where the alignment of int64_t is the same as that of double: void bar(double *f, int64_t *j) { *(int64_t *)f = *j; } void foo(void) ...
The dictionary methods .keys(), .values(), and .items() all return view objects. Said objects reflect any changes to the underlying dictionary. This is often useful. Is there a way to get such a v...
MEMCMP simply compares the memory bits between two locations. This has nothing to do with whatever those bits might mean. Your first example, on the other hand, compares the contents of variable ...
Quick answer (DATE_PART(dayofweek, my_datetime) + 6) % 7 Slow answer For avoidance of doubt, here is what I believe you currently have (assuming an input called my_datetime): DATE_PART(dayofw...
I have a query summarizing some transaction data that I'd like to summarize by day of week. For my use case, I need to return weekdays formatted according to ISO 8601, so Monday must be the first d...
I'm trying to subclass pdb to have a debugger that, in case of a call to a decorated function, can "step in" the decorated function directly and skip the decorator content altogether. A well-behave...
The Code using Microsoft.EntityFrameworkCore; public class BloggingContext : DbContext { public DbSet<Blog> Blogs { get; set; } public DbSet<Post> Posts { get; set; } ...
Well, minutes after posting my question, I found the disappointing answer: no. Original answer found on https://www.mathworks.com/matlabcentral/answers/184191-can-i-have-subdirectories-in-a-packag...
