python - Setting array element with sequence -


Run this code: Python simulation to calculate potential difference of rod

Setup Details: Visual Import from Visual Import * From __future__ Import Division 

  View = Display (X = 0, Y = 0, width = 600, height = 600) Graph = Gdisplay (x = 600, y = 0, width = 400, height = 300)

Code body: 

  # objects Vgraph = gcurve ( Color = color.Sation) marker = spherical (pause = vector (0, .15,0), radius = .05, color = color. Ed) marker.v = vector (0, .5,0) #Constants e = 1.6e-19 oofpez = 9e9 scale = 8e-3dt = 0.001 # initial value l = 2 ## Rod length N = 100 ## Point Charges Q = 3e-8 dQ = Q / NDX = L / nt = 0x = (dx-L) / 2 dVtotal = 0 Annet = Vector (0,0,0) ## Calculating x & Lt; L / 2: spherical (pause = (x, 0,0), radius = 1/6, color = color.sean) x + = dx while marker.pos.y & lt; 1.15: x = (dx-L) / 2net = vector (0,0,0) while X & lt; L / 2: r = marker.po - vector (x, 0,0) rmag = meg (r) rHTH = r / rmag e = orphase * dq / rmagad2 * rhp annet + = e x + = dx dv = - Dot (Annet, .0005), Detachable = DTT + DVT = T + DT Marker.Pause = Marker.Po + + Marker. * DT Wigraphflot (Pause = (T, DVT)) Print ("DitTatal =", Digitotle, "Voltage")

produces this error: 

  traceback (most recent call final): the file "F: / Purdue / Second Semester / PHYS 272 / accrue / lab5.py", line 49, & lt; Module & gt; Vgraph.plot (pos = (t, dVtotal)) file "C: \ Python32 \ lib \ site-packages \ visit \ graph.py", line 742, in plot position, c = primitiveargs (self, args) file "C : \ Python32 \ lib \ site-packages \ visit \ graph.py ", in line 708, primitiveargs pos = array (argument ['pos'], float) Value error: Setting an array element with a sequence.

How do I fix this?

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
