problem running getDoubleArray

[KhanSimeoni]

Hello, I have been trying to use getDoubleArray, but I keep getting an error. I am using it in the following code:

table = NetworkTables.getTable("ML")

while 1:
    object1posX = table.getDoubleArray('boxes',0)

Unfortunatly, this returns the error:

AttributeError: 'NetworkTable' object has no attribute 'getDoubleArray'

Any idea what i'm doing wrong?

Use getNumberArray instead.

That returned the error

TypeError: 'int' object is not subscriptable

What's the full stack trace?

Is this what your looking for?

python3 test_network_receive.py 10.17.21.2

    print("The center is at " + str((object1posX[3]-object1posX[1])+object1posX))

The default value that you passed to getNumberArray is an integer, which is returned if the value isn't present in NetworkTables. Integers are not subscriptable, as the error message says.

Try getNumberArray('foo', [0,0,0,0]) instead. Or use None as the default, and check to see if the value is None and don't print if it is.
