This error occurs because the method getAverageFrameRate() is not defined in the MyApp class. To fix it, we can add the method to the class:

from direct.showbase.ShowBase import ShowBase

class MyApp(ShowBase): def init(self): ShowBase.init(self) self.accept("escape", self.quit) self.taskMgr.add(self.printFrameRate, "printFrameRateTask")

def printFrameRate(self, task):
    frameRate = self.getAverageFrameRate()
    print("Frame rate: {0:.2f} fps".format(frameRate))
    return task.cont

def quit(self):
    self.userExit()

def getAverageFrameRate(self):
    return globalClock.getAverageFrameRate()

app = MyApp() app.run()

In this updated version of the code, the getAverageFrameRate() method is defined in the MyApp class, and simply returns the value of globalClock.getAverageFrameRate(). This should resolve the AttributeError and allow the program to run as expected
