The way you are using lapply is not correct. Take a look at the documentation for lapply

lapply returns a list of the same length as X, each element of which is the result of applying FUN to the corresponding element of X.

There are some confusions you are making using lapply and in the function you are declaring inside lapply.

But I think this is the kind of task that the functions in the tidyverse package are perfect for (rearranging your dataset in a different format).

So I think it is more useful to show you how to do it with tidyverse. Take a look at their tutorial. It will be very useful!

Using their functions you can accomplish what you want with few lines of code:

You need to leave enough time for page to have fully loaded. So look for something on the page that is only present when all desired data loaded and then test for that. I often test for number of rows in a results table for example.

Personally, if scraping is permitted, I would switch to xmlhttp to avoid the timing issue. You can alter the per_page and get more results with less requests. Here is an example:

You will need a json parser, such as jsonconverter.bas, to parse returned json into table if desired.

New Thread for Different Api Calls

Asked 2020-Jun-12 at 22:54

I am looking to make a different thread for different api calls, because of the runtime. I do not know much about threads, so feel free so correct me if this is the wrong way to go, it was just suggested to me by someone. Any help would be appreciated. And for each api call I set that API to a variable, meaning, in each thread I would need access to that variable as well as creating a new thread at the same time. Again, I am inexperienced, so cut me some slack please.

I know hwo to create threads, but i am not sure how to implement this into what I need based on the google searches I have done

You don't need to create Threads manually in this case, just use Task.WhenAll to wait for all created tasks (removing await before grabData):

Replace method not removing string from pandas dataframe column

Asked 2020-Apr-20 at 09:01

Hi I have a pandas dataframe column which I need to set as numeric.

First I need to remove the 'M' (for millions) from the data. Then I can use to_numeric function. But the end result seems to just be a series of NaN's. Looking further into it, the numeric method isn't working because the column still contains an 'M" - hence the replace method isn't working.

Why is the replace method not removing the 'M'?

...

ANSWER

Answered 2020-Apr-20 at 08:59

Maybe you can try another way by using this df.Value=df.Value.str[:-1] to remove the M.

Web Scraping ETFs Daily Data VBA

Asked 2020-Apr-09 at 20:04

I'm trying to web scrap some daily info of differents ETFs. I found that https://www.marketwatch.com/ have a accurate info. The most relevant info is the open Price, outstanding shares, NAV, total assets of the ETF. Here is the link for IVV US Equity: https://www.marketwatch.com/investing/fund/ivv

I have web scraped with VBA before but the HTML of the pages I had used are different, I don't know if this is because some values of the ETFs (such as Price and Taded Volume) change constantly. The idea is to create a code to extract relevant info and create a data base to analyze Macroeconomics factor using the ETFs as market indicators of flows between countries, regions, etc...

Mi first approach would be with VBA but after I get more into the data I would like to try with Python (after I get more conffident with it) to automate the webscraping process on a daily basis.

I am open to any suggestion or any other website that could be useful (I have tried with Yahoo Finance and Morningstar and I get the same problema with the HTML code).

This is my poor code:

Okay, so you will need to create two loops. You can just keep reusing the elem0, elem1, and elemColl(1) variables for each price point you need - just make sure to reset bFoundIt to False for each new iteration so you do not exit the For Loops early.

For your total_net_assets var, you will first loop the class of kv__item. You will then need to loop each class collection of kv__label within the kv__item's elements and stop when you match the innerText: Total Net Assets. Once you match this, you will use the first coll obj elem0 to get the kv__value kv__primary class name for it.

I've adjusted the XPath to try and ensure you get the right table, but as you say there isn't any id or class to distinguish it. This will look for a nested table which has tr and td combinations. Then using virtually the same code as you currently have to check if there are 2 columns and then outputting the data...
