QUESTION
I used withColumn with UDF to get a new column, then selected two columns and assigned it to a new df. But when I run count() on this new df, it gives me TypeError: 'NoneType' object is not subscriptable. show() works fine. I am trying to get the length of the new df. Here is my code:
...ANSWER
Answered 2021-Apr-06 at 07:40You probably have nulls somewhere in your dataframe, but not in the first 20 rows that you showed. That's why you got an error when counting the whole dataframe, but not when showing 20 rows from the dataframe.
To prevent nulls from crashing the program, change your udf to:

I'm trying to receive stock data for about 1000 stocks, to speed up the process I'm using multiprocessing, unfortunately due to the large amount of stock data I'm trying to receive python as a whole just crashes.
Is there a way to use multiprocessing without python crashing, I understand it would still take some time to do all of the 1000 stocks, but all I need is to do this process as fast as possible.
...ANSWER
Answered 2021-Jan-31 at 19:18Ok, here is one way to obtain what you want in about 2min. Some tickers are bad, that's why it crashes.
Here's the code. I use joblib for threading or multiprocess since it doesn't work in my env. But, that's the spirit.
QUESTION
I have a webscraper to download all the stocks from TradingView.com that meet a certain criteria, then stores the names of these stocks in a list. I then have a script to save the names of the stocks along with the date they were added, into a CSV file.
My question is why do I need to loop through a list multiple times to remove the irrelevant data? I've tried using two lists to avoid editing a list you are currently looping through.
Here's the code :
...ANSWER
Answered 2020-Nov-08 at 16:48Iterators over lists are just wrappers over looping with the index, and deleting an element shifts the entire list. Let's say you have the list [1, 2, 3]
, and you start iterating over it:
QUESTION
I'm fetching data out of a mapping API (which returns JSON) and luckily for me as a JSON noob, the object I've been wanting to manipulate in the past has been named with a shortcut.
However, today I want to get data from an object which is named with a randomly generated number, which I won't know the name of when I fetch it. So I effectively want to write:
An example of the JSON is below. The data I am trying to access is the name of the Scottish Parliament constituency. So I am looking for an object which contains [type_name] = "Scottish Parliament constituency". I then want to look for the key/value pair within for name (in this example, Glasgow Kelvin).
In this case, the object has the randomly generated name of 134955, but if I don't know that beforehand, how I can write the javascript to scope within the find if it has that type_name, and therefore pull the name out? The objects aren't always the name number and order, so I can't just do it by saying "get the first object".

I am creating my first Grafana panel plugin to display GLG grphics. I am using react simple panel plugin. For GLG implementation I am having GLG static library(can't install with npm).

QUESTION
I'm trying to display a nested SVG (path) and I'd like to manipulate the "inner" SVG so that's it's centred and scaled based on an "inner bounding box" - let's say a square 500px^2.
Here's an example but I can't get my head around the viewport and scaling to do what I need it to do.
...ANSWER
Answered 2019-Jan-15 at 11:18From what I understand, you want to have a 624*800px SVG, and in its middle an area of 500*500px in which to draw your path. To do that you can place a nested SVG of that size right where you want it. As you know the size of the outer SVG, you can easily compute the position by hand. In the markup, leave off the viewBox.
For the outer SVG you has some errors in xour code: the attribute name is viewBox
, and for the values, width coems before height:
