Python Passing Object to Object

Question

Good Day,

So I have an object called PointArray and another object called Graph. I am passing the object point to Graph as such

class Graph:
    def __init__(self):
        self.pointArray = PointArray()
    description = "This is a class"
    author      = "Raaj"

    def setPointArray(self,pointArray):
        self.pointArray=pointArray

    def plotFFTGraph(self):
        xArr=[]
        yArr=[]
        for point in self.pointArray.freqArray
            xArr.append(point.X)
            yArr.append(point.Y)

        subplot(2,1,2)
        plot(xArr,yArr)

The problem is, Python doesn't seem to recognize that I can access freqArray!

I get this

for point in self.pointArray.freqArray
                                     ^
SyntaxError: invalid syntax

I have imported everything correctly. What gives this error?

Read what the error message is saying. If it couldn't recognize that you could access freqArray, it would give you something like an AttributeError: 'Spam' object has no attribute 'freqArray'. But it's saying SyntaxError: invalid syntax—that means there's something wrong with your punctuation. — abarnert

You forgot the colon:

for point in self.pointArray.freqArray:
    #                  ---------------^
