python - Why is instance variable not getting recognized

Question

I have the following class in Python.

import os,ConfigParser

class WebPageTestConfigUtils:

    def __init__(self, configParser=None, configFilePath=None):
        self.configParser = ConfigParser.RawConfigParser()
        self.configFilePath = (os.path.join(os.getcwd(),'webPageTestConfig.cfg'))

    def initializeConfig(self):
        configParser.read(configFilePath)
        return configParser

    def getConfigValue(self,key):
        return configParser.get('WPTConfig', key)

def main():
webPageTestConfigUtils = WebPageTestConfigUtils()
webPageTestConfigUtils.initializeConfig()
webPageTestConfigUtils.getConfigValue('testStatus')

if  __name__ =='__main__':
main()

Upon execution . This gives me the error.

NameError: global name 'configParser' is not defined.

Why is python not able to recognize the instance variable here. ~

Answer 1

You are defining

...
self.configParser = ConfigParser.RawConfigParser()
...

And accessing using

...
configParser.read(configFilePath)
...

You have to access as self.configParser.
