I am really struggling with a programming task I have been handed, I have been asked to read from a CSV file which shows the names of beaches and a rating and then work out the average rating. Any help I could get with this would be great also Ithe task given to me am at a beginner level so please don't judge.
For reading CSV files, check out Python's standard library csv(https://docs.python.org/3.7/library/csv.html)
This content will have enough tutorials and readings that will guide you through your assignment.
As for taking sums and averages, Python's built-in functions(https://docs.python.org/3.7/library/functions.html) will do you enough good.
If you are stuck with any of them, feel free to add comments.
Good luck!

I would like to code a script that could locate a specific word or number in a financial statement. Financial statements roughly contain the same information, they are however not identical and organized in the same way. My thought is that by using Tensorflow I could train a neural network to locate the specific words or numbers for me. I am thinking that if I label different text and numbers in 1000 financial statements and use them to train the neural network, it will then be able to identify these numbers or words in all financial statements. For example, tell it in all 1000 training statements which number that is the profit of the company.
Is this doable? I have been working with coding in python for a couple of months and so far I've built some web scrapers and integrated them with twitter, slack and google sheets. I would be very grateful for all your thoughts on this project and if anyone could steer me in the right direction by sharing relevant tutorials.
Thanks a lot!
Great thing that you're getting started, I believe before thinking about the actual implementation using tensorflow or any other library, you should first try to understand the problem in regards with the basic domain of the problem itself.
I'm not really sure what are you exactly trying to achieve but to a rough idea I'm guessing it's about trying to find is a statement turns out to be a benificial to the company or not, something like of semantic analysis type of problem.
So I strongly believe that, first you should try to learn the various methodologies related to semantic analysis and find the most appropriate technique.
In short theory/understanding before the actual code.
Finally i would suggest you ask such theoratical questions on stack exchange of AI, here in SO we generally deal with code or something that of intermediate to code.
I hope that makes sense? ;)
drop a comment if any doubts.
I have many files with three million lines in identical tab delimited format. All I need to do is divide the number in the 14th "column" by the number in the 12th "column", then set the number in the 14th column to the result.
Although this is a very simple function I'm actually really struggling to work out how to achieve this. I've spent a good few hours searching this website but unfortunately the answers I've seen have completely gone over the top of my head as I'm a novice coder!
The tools I have Notepad++ and Ultraedit (which has the ability to use Javascript, although i'm not familiar with this), and Python 3.6 (I have very basic Python knowledge). Other answers have suggested using something called "awk", but when I looked this up it needs Unix - I only have Windows. What's the best tool for getting this done? I'm more than willing to learn something new.
In python there are a few ways to handle csv. For your particular use case
I think pandas is what you are looking for.
You can load your file with df = pandas.read_csv(), then performing your division and replacement will be as easy as df[13] /= df[11].
Finally you can write your data back in csv format with df.to_csv().
I leave it to you to fill in the missing details of the pandas functions, but I promise it is very easy and you'll probably benefit from learning it for a long time.
Hope this helps
Ive started learning Python and decided to give myself a golf related project to work on. My question revolves around choosing the best data type to use. Now i know th3nanswer to this is based on requirements but tht isnt helping me.
Besides simple data like name, date, name of course, etc., ill alao be generating 9 and 18 hole scores for multiple players in my locl society.
While keeping a historical record of past scores is nice i may want to perform some analytics across my dataset to find handicaps, hardest holes, etc. And, yes, i know there are apps out there aldeady im doing this to learn. ;)
So....which data structur should i use to work with? Lists, dictionaries, numpy arrats, objects, or a combination?
Many thanks!
I'm new to programming and do not have much experience yet. I understand some python codes, but not into detail.
I have an Excel file which contains log files of problems people encountered. The description of the problem is pasted as an email (so it's a bunch of text). I want to analyze all of these texts (almost 1.000 rows in Excel) at once, and I think Python can do this.
The type of analysis I want to do is sentiment analysis (positive, neutral, negative) or I want to see the main problem out of the text. I don't know if the second one is possible.
I copied the emails that are listed in the Excel file, to a .txt file, so now every rule is one message. How can I use Python to analyze every single rule as one message and let it show me the sentiment or the main problem?
I'd appreciate the help
Sentiment analysis is a fairly large problem in computer science/language. How specific did you want to get?
I'd recommend looking into Text-Processing for simple SA.
Their API docs are here, http://text-processing.com/docs/sentiment.html, which will return a simple pos and neg score for your text.
If you want anything more specific, I'd recommend looking into the IBM Watson, specifically Natural Language Understanding https://www.ibm.com/watson/developercloud/natural-language-understanding.html
Forgive me if my questions is too general, or if its been asked before. I've been tasked to manipulate (e.g. copy and paste several range of entries, perform calculations on them, and then save them all to a new csv file) several large datasets in Python3.
What are the pros/cons of using the aforementioned libraries?
Thanks in advance.
I have not used CSV library, but many people are enjoying the benefits of Pandas. Pandas provides a lot of the tools you'll need, based off Numpy. You can easily then use more advance libraries for all sorts of analysis (sklearn for machine learning, nltk for nlp, etc.).
For your purposes, you'll find it easy to manage different cdv's, merge, concatenate, do whatever you want really.
Heres a link to a quick start guide. Lots of other resources out there as well.

Hope that helps a little bit.
You should always try to use as much as possible the work that other people have already been doing for you (such as programming the pandas library). This saves you a lot of time. Pandas has a lot to offer when you want to process such files so this seems to me to be the the best way to deal with such files. Since the question is very general, I can also only give a general answer... When you use pandas, you will however need to read more in the documentation. But I would not say that this is a downside.
