I'm pretty sure you just want conditional aggregation:

To count something, you need to specify a group where that count applies. So every column that you select (and is not used in an aggregate function, like COUNT or SUM), you need to mention in the GROUP BY clause.

Or to put it the other way around: the non-aggregate columns must apply to all rows that are contained in that particular COUNT.

So between the WHERE and ORDER BY clauses, add a GROUP BY clause:

The comment of Bob__'s should capture the main culprit: In your loops you call deriv after the update of each coordinate. But only the last call counts. As that is done with the completely set vector, you get overall the correct result. Change to

The main problem is that the client does not know when the complete message from the server has been received. The receiving code expects the server to close the connection before it can process the incoming data. However, the server can not close the connection because it is waiting for the client to send a response over the same connection.

The client is blocked at data = connexion_avec_serveur.recv(buf) until the server closes the connection, or some other network event occurs that severs that connection. Meanwhile the server is also blocked at dat = self.client.recv(buf) awaiting a response from the client - there is a deadlock.

The solution is to arrange for the client to know when it has received the complete message from the server, which means adding some protocol. One way is for the sever to append a sentinel value to signal the end of the message, and for the client to watch for that sentinel. Another way is for the server to prepend to the message the length of the payload, in this case the length of the pickled data, which I show here.

For the client change the run() function:

You call teste.parse(someString), where teste is an expression which has type Parser. That means this is a call to the method parse(String) in your Parser type....

and that is declared with throws Exception.

Exceptions are a mechanism to convey alternate return options. The parse method can run its course in one of two ways: It can 'return', in which case it returns nothing (void), or, it can 'throw'. What it can throw is limited by its throws line - in this case, it can throw just about anything (Exception is the supertype of almost all things you can throw).

The way java handles this is that your code needs to handle every possible way a method can conclude.

So, you need a 'path' for your code when the parser() method returns (this is trivial; it's a void method, you get that 'for free', you don't need to write anything special for this), but you also need a path for that other exit scenario: When it throws something. You get handling of RuntimeException for free, but for others, you have two options:

catch it:

My approach is avoid xml parsing and switch straight into pandas by using xmlplain to generate JSON from xml.

At the voirIndexDevis function you have to do the same event into the service file but this time only receive the listeDevis with the index you sent. But i advise you to create a new variable like Devis and paste the data from that event so that variable only contain the one that you click.
