available_vr_rooms

'''

Create a function called available_vr_rooms that takes one parameter called data_path and returns a tuple.

It will typically be called with a Path object, e.g.: available_vr_rooms(data_path=Path('data', 'vrdata'))

1) RETURNS

- Because this is a utility to be called by another one of your functions, you are not to handle

any exceptions. Just let them be raised as usual and the calling function can handle them

if necessary.

- If no exception is raised, this function will return an empty tuple, or a

tuple of strings.

Then, for every .txt file in the folder (ignore any non-txt files),

2) The vrdata files each contains multiple references to ROOMNAME.

Your function needs to look in each file and

- Take a look at all the room names found in each file so that you can build a

list of room names from across all of the files.

3) If there are no room names, return an empty tuple. Otherwise, return a tuple with

*1* copy of each unique room name you found across all of the files in the specified folder.

# DEFINE AND WRITE YOUR FUNCTION HERE

room_time

'''

Create a function called room_time that takes 2 parameters. One is a string parameter called 'room'.

The other is a Path parameter called data_path. The function returns a tuple.

It will typically be called like this: room_time(data_path=Path('data', 'vrdata'), room='removing key')

Parameter Checking:

- if the room parameter is not a string or refers to a room name that does not exist in the data,

return an empty tuple and print this message:

Room "BLAH" does not exist in the VR data (where BLAH is the room requested)

- if data_path is not a valid path, return an empty tuple and this message:

"BLAH" is not a valid folder path

How to find this information:

- The data files will have a .txt extension...only read these files and ignore files with other extensions.

- In each data file in the data path, there will be several room records (each separated by a bunch of dashes).

- In each of these room records, you will find a room name and a room duration. The duration is how long the user spent in this virtual room. Collect all of these durations for each room record with the target room name.

- The general approach is this: For each file, get the room records. For each room record, if it has the target room name, find the line on which the duration is shown. From that line, get the room duration and the move to the next room record.

What to Return:

- you are returning a tuple containing all of the room durations from all room records across all data files in the

data path from that refer to the target room.

Announcing the file you're working on:

- print "Processing BLAH" where BLAH is just the file name of the path you are currently processing

'''

Update files:

data is a folder that contains 2 different folders one called room and the other vrdata, the vrdata folder consists of multiple txt files and few non txt files in the format:(101_.txt, 102_.txt)...
