As people said, when we use the command "python name.py" in the terminal to run a python script, we need to enter the parent folder of this python file so that it can be found.

Solution: We could use "cd" to go to the parent folder of the python file: (Please go to your folder "AirSim".)

I've implemented parse_csv() function inside next code that uses no modules. It supports any separator (e.g. ,) between cells and any quoting char (e.g. "), also it correctly handles separators located inside quoted strings e.g. CSV line "a,b,c",d will be handled as two cells a,b,c and d. Empty lines in CSV are skipped.

First row is handled as columns names. Function returns columns names and rest of rows separately, so that these two can be directly passed to pd.DataFrame() constructor.

Function accepts header argument (columns names), it should be True if header row should be read as first row of CSV file, it should be False or contain a list of columns names if CSV file has no header row.

Input CSV file can be passed to function by different ways 1) Through file argument which can be either string that contains file path or name, or opened for reading file object. 2) Through text argument which can be either string containing CSV text or bytes containing CSV file contents.

In simplest form you just do columns, table = parse_csv(file = 'test.csv').

Apple's iBeacon framework is dirt-simple and very easy to use. It allows you to listen for beacons based a unique UUID, major id, and minor ID. It lets you know when a beacon enters or leaves range, and provides crude (immediate, near, medium, and far) distance values. You can create "beacon regions" that will notify your app when you enter or leave them. That's about it.

If you want to do something like read barometric pressure or temperature readings, you will need to either write your own low-level BLE code or use an existing library. My guess is that these modules are using very standard hardware and that you should be able to find libraries to read their specialized data.

Failing that, you will need specifications on their BLE interface and need to learn how to write Apple Core Bluetooth code. (The link you posted has zero specifications for the units. The only thing it provides is the numbers "nRF51822 bluetooth module ibeacon LPS22HB" (It's not in well-formed English so I don't know how to parse those descriptive terms. I'd google those numbers) Note that Core Bluetooth is a fairly low-level framework and not very easy to learn.

Googling "nRF51822", that is apparently an ARM based chip that includes radio hardware that supports BLE. It sounds like that is a general-purpose chip that vendor would use to build a BLE module. Given that, you'd probably have to reverse-engineer it to figure out how it works.

The "LPS22HB" appears to be a solid state pressure sensor that can be used to build a barometric pressure measurement device. It's no doubt interfaced with the "nRF51822". Without specs you're going to have a very hard time figuring out how it's interfaced however.

Add an ID to your HTML form, so we can reference it easily - for example, icao_form:

Do it the correct and easy way. First, open any word document and change everything to be exactly as you want it: font, indents, margins, etc. Then save that layout as a new Style. Then over in officeR all you need to do is specify that style rather than "Normal."

If something like page margins aren't included in the Style (I forget at the moment), then go one step farther, again in Word. Do everything I listed in the first paragraph. Make sure there's no text or pictures or whatever in the document (completely blank). Then SaveAs and select ".dot" or ".dotx" to save as a document template. Now when you run officeR you can specify that template and a new ".docx" file will be created. You can name it and save it with officeR commands.

In C++ I would store pointers or references

Rust isn't that alien. You do the same thing. The main difference is that Rust prevents you from being able to mutate one thing via two different paths or to have a reference that dangles.

Answering your question has many potential solutions. For example, you don't describe whether you need to be able to mutate the sensors or describe if the sensors will outlive the manager, if threads will be involved, etc.. All of these things affect how micro-optimized the code can be.

The maximally-flexible solution is to:

1. use shared ownership, such as that provided by Rc or Arc. This allows multiple things to own the sensor.

2. use interior mutability, such as that provided by RefCell or Mutex. This moves enforcement of a single mutating reference at a time from compile time to run time.

3. use trait objects to model dynamic dispatch since the decision of what concrete objects to use is made at run time.

Michele. Your project look like my project when I was in college. I had to use GPS data to apply data fusion algorithms in it. Since I hadn't access to the GPS device all the time, I have written some gps data into a file and used that file as a real device data. It really worked for me.

Example: When reading the real GPS device it returned the string below:
