Understand the syntaxe X[Y == c] in Numpy


Understand the syntaxe X[Y == c] in Numpy

Hope that helps Please I don't understant how this syntax works: current_x = X[Y == c].
code :
# this returns a list of True or False depending if Y[i] == 5 for all i in Y
Y==5 => [False, False, False, False, True, False, False, False, False, False]

# this is known as boolean indexing ...
X[ [False, False, False, False, True, False, False, False, False, False] ] => your output

like below fixes the issue An if statement is a sequential statement, and from your usage should either be in a process statement or you should instead use a concurrent signal assignment statement. It hardly seems complex enough for a process statement.
Concurrent assignment statement:
code :
 Cout <= A(3) and B(3);
Cout <= '1'  when A(3) = '1' and B(3) = '1' else '0';
if A(3) = '1' and B(3) = '1' then
    Cout <= '1';
end if;

I wish this helpful for you There is short-cut syntax for getting the string but not for creating the object from the string to date in PHP. See the following code in which I also include a 'myEntityName' class:
code :
<?php

class myEntityName {
    public function __construct(){
        echo "Greetings from " . __CLASS__,"\n";
    }
}
class MyClass {

    /**
     * @return string
     */
    public function getEntityName() {
        return 'myEntityName';
    }
}

$entityName = ( new MyClass() )->getEntityName();
$entity = new $entityName();
$entityName = new ( ( new MyClass() )->getEntityName() );

around this issue See,
The Spark uses with Scala some Functiona Principles like Maps, Reduces and Etc...
code :
123 A
456 B
(("123", "A"), ("456", "B"))
Map("A" -> 123)
Map("B" -> 456)
Map("A" -> 123, "A" -> 669)

should help you out SOURCE is MySQL client command which means it is executed by MySQL shell, not by MySQL server, so you can't execute it via QSqlQuery. You can work around this by reading whole file and then sending it's contents to server.

it helps some times There are at least two ways:
See the picture as the example, make a table under columns E and F, then under column C, enter the formula =VLOOKUP(B2,$E$2:$F$5,2,1) then drag/copy it down to the end of records. You should see the reults like I have here. The benefit for this is when the group score changes in column E or F, you don't need to change anything in column C.
