Fixing 'AttributeError: 'MyApp' object has no attribute 'getAverageFrameRate'' in Python

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.
