QUESTION
I am trying to make a game where you can form all the different words from one other word by scrambling some letters from the main word. I have a list of subwords, but if the main word has a double letter (Like 'r' in this case) it won't add strings with a single r to the victory list. How can I fix this?

Answered 2022-Feb-17 at 02:11You can access the counter's key and value through a for loop and obtain the desired key through value comparison.

QUESTION
I have the following issue:
I have two dfs, called
df1
anddf2
.With the given
ifelse
function I try to find all rows in thedf2$Index
which starts with the same three characters as indf1$Index_1
.Search all cells starting with
CEE
.Then take all the growth values and thedf2$Index
values that are atCEE
and one before (Period 1). etc. The df: Result1 shows what the final result (just for the first row) looks like.The function should run through the entire vector Index_1 & Period. At the end there should be 5 dfs with the result.
The
ifelse
function should identify the start point, and if the point was founded, then it should use the number in the period list to give the Growth anddf2$Index
values back, as already mentioned above. I tried it with theifelse
function but I am sure there is a better and easier way to do this, moreover, theiflese
function is not complete due to my lack of knowledge in R. It would be very nice if someone can help me.

QUESTION
The following is my code to download a webpage (writing a basic wget)
HTTP request:
...ANSWER
Answered 2021-Sep-07 at 20:26You are not taking the HTTP response's Transfer-Encoding: chunked
format into account.
In fact, you are not even taking the HTTP protocol itself into account. Your code is completely ignoring the fact that HTTP has structure and rules to how it works. You are just reading raw bytes from the socket, decoding everything to Unicode using UTF-8 (corrupting everything that should not be decoded), printing the Unicode to the terminal, and then copy/pasting that into a text file with a .gz
extension. GZIP is not text.
Not all of the HTTP response data is GZIP data, some of it is HTTP chunk data instead. You need to actually process the HTTP protocol correctly. Read ONLY the HTTP response headers first, then PARSE them to determine the format of the response body. IF the response is chunked
, then READ AND PARSE the chunks properly, saving ONLY the data portion of each chunk into the output file, as-is as binary not text.
See my answer to Differ between header and content of http server response (sockets) for more details about this.
For instance, the '27'
that f.read()
is complaining about is from the initial 272b
in the response, which specifies the byte size (10027) of the GZIP data stored in the 1st chunk. You are saving the entire chunk to the .gz
file, not just the GZIP portion of the chunk.
There can be more than 1 chunk present, so you have to read and parse each chunk individually. The response data will be terminated by a chunk with a size of 0 bytes.
See RFC 2616 Section 3.6.1 and RFC 7230 Section 4.1 for more details on how HTTP's chunked
encoding works.
QUESTION
We want to use tarantool in out project that is based on kotlin language and spring framework so we tried the spring-data project for tarantool which is cartridge-springdata. The example explained in cartridge-springdata does not work when language is kotlin. The same example works when everything is in Java. The following stack trace is given:
...ANSWER
Answered 2021-Jun-26 at 05:08What akudiyar said is right. kotlin does not include reflection by default. It should be declared as a dependency separately. The problem explained in question has occurred because it needs reflection to do what it needs to do but kotlin reflection is not included in project. So adding kotlin-reflect to project fixed the problem.

I have a file like this, '¬' represents a line break.

Answered 2021-May-16 at 11:21My workaround for doing this is like follows:
add sufficient spaces to the end of all lines to allow using visual block mode later:
20A
j.j.j.

use visual block mode to insert the column inside the spaces
delete trailing spaces again (
:s/\s*$//

QUESTION
Trying to use Google Blogger API v3.0
Have a test blog set up - https://msi-blogger-api-test.blogspot.com/
Blogger User ID is - 11970463155418365784 As appears in - https://www.blogger.com/profile/11970463155418365784
Have both "API key" and "OAuth 2.0 token" set up for this project -
In the Blogger sand box it works perfectly -
Copied the cURL from the Blogger sand box.
Copied "API key" and "OAuth 2.0 token" from console.cloud.google.com (screenshot above) via the "copy" button (as highlighted in the screenshot).
Trying from CLI via cURL, works when using the "API key" alone -
Trying from CLI via cURL, DOES NOT work when using the "API key" and "OAuth 2.0 token" -
Tried to use the "OAuth 2.0 token" in both these ways:
- 1008747252329-g8j8...ebb.apps.googleusercontent.com
- 1008747252329-g8j8...ebb
Thought maybe the ".apps.googleusercontent.com" suffix is not rquired.
This did not make any difference.
So, what am I missing? Why does the "API key" works but "OAuth 2.0 token" does not?
Yes, I do not need to use the "OAuth 2.0 token" for the cURL in this (API "get") example, but it should still work.
When I'm trying a different API, say "listByUser", that requires the "OAuth 2.0 token" - it does not work and I get the same error.

Answered 2021-May-16 at 16:32So, what am I missing? Why does the "API key" works but "OAuth 2.0 token" does not?
To directly answer your question. API key only works with public data, Your not sending a valid access token as the OAuth 2 bearer token, the value you are sending is wrong.
Api KeyFirst off an API key will only give you access to public data, so you could for example use an API key to list public videos on YouTube, or look at one of the public holiday calendars on Google Calendar. You can not use an API key to access private user data
To access private user data or any method that requires authorization you need to supply a authorization header and submit a valid bearer token.
"OAuth 2.0 token"Your issue is that you are not submitting a valid access token. it looks like you may be trying to send the client id from your project on Google cloud console. This is not an access token.
How to get an access token with curl.How to get an access token with CURL is a three step process the first step being requesting authorization of the user who owns the data
This is a HTTP get call and can be placed in any browser window.

QUESTION
Situation: I have a weather GUI made in tkinter. It gets data from an api and and displays it on a tkinter label. One of the functions 'format_alerts' parses json data from the api. Because the way the data is formatted I'm having trouble parsing it for what I need.
Problem: I came up with a really weird way of parsing the data. The json uses '...' and 'astrix' to separate values in a string (inside a dictionary). I use .replace('\n', ' ') to get rid of newlines. I use .replace('astrix', '@') and .replace('...', '@' to find the split points. Then use .split('@') then reference the list index number. However sometimes the json uses '...' randomly so I end up messing up the indexing. I know regex is a better way to do this but for the life of me I can't get a three part regex search to work.
My present code looks like:
