definetly the best starter video for python for finance! thanks

[@faridparvez]

Great video, very clear. Please make a video on roadmap to learning python from scratch, specifically for stock analysis, chart analysis, getting trade signals using charts and statistical analysis of stocks. I mean create a roadmap on the course tailored cut for only stock analysis . Regards Farid

[@rickcheung1431]

Excited to see more! Thanks

Otherwise this also works - My(6px) Pos(r) smartphone_Mt(6px) W(100%). I noticed the class ID currently on the page today is slightly different from what we have in the video.

Hi, I tried this code, however I got [ ], [ ] as output for NSE stock. Is there anything that I need to change in code for Indian Stocks?. Please advise. Thanks.

[@eMasterClassAcademy]

Hi Mahendra, thanks for watching the series. Since Yahoo has updated its html at the back end, if you still would like to use Beautifulsoup to capture the data, you need to change a bit of the code. Please see the updates from #17-18 kzbin.info/www/bejne/d2q1m2pteLCjgJo However, I would also recommend to use Selenium which is more stable (but slower). Please also see the updates from #19-21 kzbin.info/www/bejne/Y4a5p5aFg7OnbpI Here I assumed Yahoo has stock data for India. Hope it helps.

I figured it out I had a unnecessary space in the return function: def web_content_div(web_content, class_path): web_content_div = web_content.find_all('div', {'class': class_path}) try: spans = web_content_div[0].find_all('span') texts = [span.get_text() for span in spans] except IndexError: texts = [] *****(space that was not supposed to be here) return texts

[@kyleryxn]

For some reason, my code only returns the price change and percent change and doesn't include the current price. How can I fix this? please post a link to source code

[@martinwendling6673]

same issue

[@jameskaddissi6600]

Ok, here's the answer. Basically yahoo finance changed their html code. I had to look back through it, but the 'span' class which we are searching through is only used for displaying the price change and percent change. The easy fix is to change the line spans = web_content_div[0].find_all('span') to spans = web_content_div[0].find_all('fin-streamer'). If you make that change and run it, it will return the price and price change, because you are only looking for the first two bits of data. If you also want the price change you have to add a third array [], so rather than price, change = [], [] you have to make it price, change, pct = [], [], [] for every line where you see that.

its not reading the first span. It´s always jumping for the next. In resume its reading only the change, not the price.

any Idea why pd.to_excel overwrites the first row over and over again? I've tried it with pd.to_csv but when I use transpose() it starts writing all the info in the first column and doesn't come to the next.

the yahoo fin page does not have a span around the data, its now a class.

[@eeshanchanpura3356]

Do you have anything regarding stock option simulator thing?

[@eMasterClassAcademy]

Hi Eeshan, thanks for your questions. This is indeed one of the projects in my plan. Although it is not yet out, it's not difficult to do so as long as you can have enough target data (e.g. minutes data of certain stock / index / option) for simulation. 1) For data, here is a video to show how we can retrieve 2 years of data at 1 min interval - kzbin.info/www/bejne/f5e4g2SOf8aAmck 2) For backtesting, you can find details from python #8 - #16 - kzbin.info/www/bejne/oYjQqJaHfsiIgrc 3) For simulation, you can follow the lessons #22 - #29 - kzbin.info/www/bejne/mYfRpYqGaMSSg9k and simply change this line of code: filename = str(time_stamp) + ' stock data.csv' At the same time, you need to create a separate py. program which appends the data one by one from the data retrieved by 1) in a csv with filename in 3). Hope it helps. Let me create a video to show you how to create a separate program for appending data in a defined csv file later.

[@eMasterClassAcademy]

You need to check if you retrieve something from the “div” content first. If yes, then you can find out the “span” that capture the required data. If not, then the “div” doesn’t return you any values. You might need to switch to other “div” or find other sources. Make sure there is no typo. Happy web scraping!

Hi, thanks for the video. How do I set up PyCharm the way you have sr?

[@deanemarks8611]

Hey man I'm now too. The first part is make sure in your virtual environment you have the right packages installed.... So basically file new project.... You are basically making a new environment that is blank... then when you get in pycharm to a text editor look near the bottom.. there is "python packages". you have to install all the packages he uses like pandas, beautiful soup, requests etc. from there make sure you "configuration" is set up to the file you are currently working on or basically you cant run anything in pycharm.... Kind of stupid how that works, but if you get that set up right, now your fishin with Dynamite brotha!
