DataFrame not showing complete table data

I web-scraped some information about S&P 500 stocks from this website: https://www.slickcharts.com/sp500. The actual web-scraping bit works fine, as if I add a print statement after the for loop included, all data is displayed. In other words, the code:

Because you keep reassigning company, symbol, weight, etc. on each iteration, these variables only hold the values from the last row you parsed.

You can use pd.read_html instead. It returns a list of data frames, one for each

How to read library errors c++

Asked 2021-Jul-06 at 19:51

I was compiling a c++ project to simulate a language changing over time from a small subset of introduced words, it was working fine until it wouldn't compile and outputed library error garblygoook. Normally this wouldn't be an issue I can debug normal errors on my own, but the error message is very unreadable(at least to a beginner) it appears to be some werid library error, perhaps connected to the standard algorithm library. I need some help to decode it and understand what is going wrong. Any other tips and tricks for reading these werid messages in the future would be much appreciated. Note: I'm using mingw on windows, with c++17.

monitoring stock prices on yahoo finance efficiently

Asked 2020-Dec-15 at 07:39

I am currently trying to get live stock prices using the beautifulsoup and requests library from the yahoo finance website. I'm currently finding that the bottleneck for speed is that the request for the webpage takes around 0.5 seconds on average. Below is my code and output

This seems a reasonable time for what you are doing (downloading and parsing a webpage).

In real I think that 0.4s should be enough for monitoring, but if you really need to have an higher update frequency (ie. you have got some new crazy trading algorithm) you can:

Try to parse a more lightweight page. (But you need to find one!)
Create a pool of thread performing many requests at the same time. You should note that this behaviour could lead to a violation of yahoo ToS and restrictions on your account/ip could be applied.
Use any sort of market API (free or payed) to avoid downloading an entire webpage and all its dependencies when you can just have something like a 20byte json (or similar) message. Also in this case you should read about the max pooling frequency you can use.
Use Selenium and perform just 1 connection to the webpage. When you detect any changes in the div you are interested in you get the updated value.

In spring data elasticsearch, can aggregation queries be put in a respository implementation?

Asked 2020-Jul-26 at 20:27

I'm using spring-boot-elasticsearch for the first time. I've now figured out how to describe my serial difference pipeline query using elastics java api. This query, as you'll see below is rather large, and returns several buckets for each object as well as the serial difference between each bucket. The examples I see of search in a Spring Data Repository all seem to spell out the query's json body in a Query Annotation like this:

ANSWER

Answered 2020-Jul-26 at 20:27

Ok, so if I get it right, you want to add an aggregation to a repository query. This is not possible with the methods that are automatically created by Spring Data Elasticsearch, but it is not too hard to implement it.

To show you how to do this, I use a simpler example, where we have defined a Person entity:
