Add an element in each value of a column

Asked 2021-Jun-15 at 12:40

I have a column that gives the date (its type is str) and another column that gives a first name, I would like all the names that are in 2020 have "_2020" at the end of their first name, and same thing for 2021, and its pandas DataFrame.

As I have thousands of rows, I need a loop that automates the task.

it would be like going from this:

Time Name 2020-12-26 John 2020-05-06 Jack 2021-03-06 Steve

To That:

Time Name 2020-12-26 John_2020 2020-05-06 Jack_2020 2021-03-06 Steve_2021 ...

I suggest that you use Sheet.getRange(row, column, numRows, numColumns) and Range.getValues() to get the row values with multiple columns.

How do I silence PyAudio's noisy output?

Asked 2021-Jun-13 at 20:51

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:

...

ANSWER

Answered 2021-Jun-13 at 20:51

The problem was that PyAudio loads a bunch of non-Python stuff whenever it's envoked, and it's that's stuff that's printing to STDOUT so it has to be silenced directly. The cleanest way to do this is to wrap it in a context manager that silences STDOUT for the shortest amount of time possible:

Update a nested value from a Json field

ANSWER

Answered 2021-Jun-13 at 20:27

This is very awkward, nearly impossible with MySQL's JSON functions.

You can use JSON_REPLACE() or JSON_SET(), but both require that you know the path to the field you want to change. So in this case, we can see that the array element is $[1] but if you didn't know that, you couldn't use this solution.

QUESTION

How to reformat a corrupt json file with escaped ' and "?

Asked 2021-Jun-13 at 11:41

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:

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

How does iterating over HashMaps work in memory: Rust

Asked 2021-Jun-12 at 21:32

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.

...

ANSWER

Answered 2021-Jun-12 at 10:31

At the end of the intro of the documentation, it is mentioned that the implementation relies on a C++ implementation of SwissTables. This page contains illustrations about two variants: « flat » and « node » based.

The main difference between these two variants is pointer stability. In the « node » based version, the key-value pairs, once inserted, keep their address in memory even if the hash is reorganised. In the « flat » version, some insertions/removals can make the previous key-value pairs be moved in memory.

When it comes to the Rust implementation, I am not experienced enough to be certain of any specific detail, but I tried this simple example based on yours.
