You could write a regular expression to solve this, but if you know that you always want to remove the content between the first and ninth stars, then I would split your strings into lists by "*" and rejoin select slices. For example:

QUESTION

Pandas - row selection with column operation & .loc[]

Asked 2021-Jun-09 at 23:04

I have been practicing with pandas and have the following problem. I have been practicing with an Olympic medal data set where the countries are listed in one column, and the medals in subsequent columns.

As part of a QC check, I wanted to write a line of code that checks that the sum of the gold (01 !), silver (02 !) and bronze (03 !) medals is equal to the value in the 'total' column. I have tried this a number of ways, including .apply with the function below, and also with .loc[] (see code below). However, I keep on getting errors back. Can someone explain where I am going wrong?

To expand, the idea of the code would be to select all rows where the sum is correct, and exclude those which are not. I have shown two of the methods I have tried below.

I am new to python and coding in general so apologies if my question is not clear enough.

Many thanks

Luke

I found a solution to my problem. In fact, just as I suspected, there was a missing directory to my PYTHONPATH. It was the directory that contained the gtts package.

Solution: If you have the same problem,

Find the package

I looked at that post

Add it to sys.path (which will also add it to PYTHONPATH)

Why does drawing a qiskit quantum circuit look different when I run a jupyter notebook locally

I'm using the qiskit textbook, and it creates a QuantumCircuit and then draws the circuit, and it looks like this:

I see the same result when running the textbook as a jupyter notebook in IBM's quantum lab.

However, when I download the textbook as a jupyter notebook and run it myself locally, it looks like this:

ANSWER

Answered 2021-Jun-05 at 17:40

Because Qiskit has multiple drawers. Those are:

text
mpl
latex
latex_source.

The drawer you see in the IBM Quantum Lab is the one based on Matplotlib. You can get the same output by qc.draw('mpl').

To set a default, you can change (or create if does not exist) the file ~/.qiskit/settings.conf) with the entry circuit_drawer = mpl.

Video Poker How to make the combinations?

Asked 2021-Jun-03 at 12:52

I have been stuck on this for quite a while. So I thought I'd look it up. But with hours of searching I have come to ask on stack overflow as I am completely stumped.

Basically I am making a Web implementation of Jacks or Better: Video Poker. For some reason I keep getting my kings queen jacks and tens are recognized as the same value. And my full house keeps on being awarded. If my explanation isn't great then go to here or here to find out about the combinations.

If I need to send more code like the style tag I can do so, but I think this is all that is necessary. Any help is appreciated even ways to shorten down my code!

Replace Id of one column by a name from another table while using the count statement?

Asked 2021-Jun-01 at 07:46

I am trying to get the count of patients by province for my school project, I have managed to get the count and the Id of the province in a table but since I am using the count statement it will not let me use join to show the ProvinceName instead of the Id (it says it's not numerical).

Here is the schema of the two tables I am talking about

The content of the Province table is as follow:

ProvinceId ProvinceName ProvinceShortName 1 Terre-Neuve-et-Labrador NL 2 Île-du-Prince-Édouard PE 3 Nouvelle-Écosse NS 4 Nouveau-Brunswick NB 5 Québec QC 6 Ontario ON 7 Manitoba MB 8 Saskatchewan SK 9 Alberta AB 10 Colombie-Britannique BC 11 Yukon YT 12 Territoires du Nord-Ouest NT 13 Nunavut NU

And here is n sample data from the Patient table (don't worry it's fake data!):

C++ creating a std::vector from std::string array

I am learning about c++ and was following a course. A final exercise involves making a program for deck of cards. I have thought of an approach:

I initially tried to do everything with string arrays but realised that it would make more sense to use vectors since. I am now trying to create a std::vector std::string out of my std::string array but with no luck.

Rules for memory allocation.

Do not allocate so much RAM that swapping will occur. Swapping is terrible for MySQL/MariaDB performance.
Do adjust innodb_buffer_pool_size such that most of RAM is in use during normal time and even for spikes in activity. (I often say "set it to 70% of available RAM", but you are asking for more details.)
Do not bother changing other settings; they add to the complexity of "getting it right".

There are 3 situations (based on innodb_buffer_pool_size and dataset size):

Tiny dataset -- buffer_pool is bigger than necessary --> wasting some of RAM, but so what; it is not useful for anything else. And it give you some room for growth.
Medium-sized dataset -- Most activity is done in RAM; the system will run nicely.
Big dataset -- The system may be I/O-bound. Adding RAM is a costly and brute force solution. However, some software techniques (eg, better indexes) may help, such as this for WordPress and WooCommerce.
