I have a dataset of jobs for a gardening company with 50 or so columns.

I have a dataset of jobs for a gardening company.

I have a SQLite table like this:

I want a new SQLite table to show share of each person. It needs to do the calculation to split the cost for each item between the people.

Please advise what query I need to run on sql to get this new table.

I've installed PyAudio and it's working exactly as I want it to, both for playing and recording audio. However, every time I initialise a PyAudio object, it barfs a whole bunch of warnings and error into STDERR and it's making it difficult to sort through my own application's logs. Here's a sample out of an ipython session:

Consider this table:

Problem

I have a large JSON file (~700.000 lines, 1.2GB filesize) containing twitter data that I need to preprocess for data and network analysis. During the data collection an error happend: Instead of using " as a seperator ' was used. As this does not conform with the JSON standard, the file can not be processed by R or Python.

Information about the dataset: Every about 500 lines start with meta info + meta information for the users, etc. then there are the tweets in json (order of fields not stable) starting with a space, one tweet per line.

This is what I tried so far:

1. A simple data.replace('\'', '\"') is not possible, as the "text" fields contain tweets which may contain ' or " themselves.
2. Using regex, I was able to catch some of the instances, but it does not catch everything: re.compile(r'"[^"]*"(*SKIP)(*FAIL)|\'')
3. Using literal.eval(data) from the ast package also throws an error.

As the order of the fields and the legth for each field is not stable I am stuck on how to reformat that file in order to conform to JSON.

Normal sample line of the data (for this options one and two would work, but note that the tweets are also in non-english languages, which use " or ' in their tweets):

I have an array of objects and I want to check whether a given object is present in the array and if yes,I want to delete that,If not I have to add it to the array.

I am doing this:

Lets say I had this sample of a mixed dataset:

I know how to iterate over a HashMap in Rust, however, I am a little confused about how this works in memory. How do we iterate over values that are not stored sequentially in memory? A detailed explanation of the code below at the heap and stack level would be much appreciated.
