QUESTION
I have a data.frame with a column containing California counties in each cell separated by a space. I would like to add a comma and space after each one, however I can't just gsub every space into a comma and space, (i.e. gsub("\s",",\s",text)), as some counties in California have two names, (e.g. Los Angeles, San Francisco, etc.)
Fortunately, the two-word counties all have common first words so I'd like to write a gsub that preserves the space in those counties without adding a comma. I've attached example data as well as what I'd like the final form to look like. For instance, with this data, I'd like to add a comma and space except after "El", "San" and "Del".
Example data:
...ANSWER
Answered 2021-Jun-05 at 00:29Given that you know you are only looking for California counties, one "easy" way is just to replace only spaces that occur after a California county. To get that regex, I just concatenated the CA county names together with |
and added a space. The gsub
will replace any county name followed by a space with the same county name (\\1
), a comma, and a space.
QUESTION
What Python Ethereum client is meant for smart contract interaction ?
(mostly ERC20 tokens methods balanceOf
, transfer
)
I guess web3.py is older and low level close to JSON RPC.
But newer Trinity in in alpha.
...The Trinity client is currently in an alpha release stage and is not suitable for mission critical production use cases.
ANSWER
Answered 2021-Jun-03 at 06:35You do not need a "client", or run your own "node", you need a library and some API service provider.
For JSON-RPC API services check Ethereum nodes.

...ANSWER
Answered 2021-Apr-27 at 16:44You can do it with the $event
parameter.
Make sure to compare your values safely.
If your value is not in the right type or has spaces or unwanted chars, this c.state == val
might not work.
You can use the trim
function to compare your value safely:
c.state.trim() == val.trim()

QUESTION
I need a python package that could get the related sentence from a text, based on the keywords provided.
For example, below is the Wikipedia page of J.J Oppenheimer -
...ANSWER
Answered 2021-Apr-12 at 21:19I am pretty sure a Module exists that could do this for you, you could try and make it yourself by parsing through the text and creating words like: ["date of birth", "born", "birth date", etc] and you do this for multiple fields. This would thus allow you to find information that would be available.
The idea is:
you grab your text or whatever u have,
you grab what you are looking for (example date of birth)
You then assign a date of birth to a list of similar words,
you look through ur file to see if you find a sentence that has that in it.
I am pretty sure there is no module, maybe I am wrong but smth like this should work.

option to instruct DataTables where your data array is located inside the JSON response structure. This is where DataTables will begin its row-by-row iteration.
This requires a change to your ajax
