Problems using classes in Python3

[tunisia]

I'm trying to modify this code to take advantage of classes and
some other oop features. However, I'm struggling with getting beyond the basics.

This is the code that I started with which I am trying to change and make more class absed.

import glob
import os
import sys
print(os.getcwd())
dir= raw_input(["Please enter directory location of dcp_inspect output"])
print (dir)
os.chdir(dir)
print(os.getcwd())
cpl    = []
content = []
errors = []
contentkind = []
summary = []





for file in glob.glob("*"):
    try:

        print (file,'\t Was Successfully Opened')
        #file = DcpParse()
        newfile = file
        print('Scanning...', newfile)
        data = open(newfile)
        for each_line in data:
            if 'CPL Id:' in each_line:
                cpl=(each_line.split())
            elif 'ContentTitleText:' in each_line:
                content=(each_line.split())
            elif 'Errors' in each_line:
                errors=(each_line.split())
            elif 'ContentKind' in each_line:
                contentkind=(each_line.split())
            elif 'Composition summary:' in each_line:
                summmary=(each_line)


        print('CPL=',cpl[2]) 
        content.index('ContentTitleText:')
        content.pop(0)
        print('File Name on DCP',content)
        print('Content Kind =',contentkind[1])
        errors.pop(0)
        print('There are',errors[0],'Errors and',errors[2],'hints for', content)
        if errors[0] != '0':
           print('could be issues')
        else:
            print('This DCP appears to be OK')
            #print(summary)
        data.close()

    except:
        pass        

That code changes to a directory where the files are located as specified by the user
and then parses some text. I want to do more with dictionaries, K/V and so on in the other script.

In this code I'm struggling with how to arrange my classes and the methods. I've commented out a lot
in order to get it to run and debug. But I'm not making much headway.

import os
import glob
import sys
import subprocess
import dcp_parse_gmail

print(os.getcwd())
dir= input('Please enter directory \n')




os.chdir('/Users/zacharymanning/Desktop/dcp_output')

print(os.getcwd())

class Parser:   # or `class Parser(object):` in Python 2
    '''Reads DCP manifest files into Python dictionaries.'''

    def __init__(self,path):
        '''Constructs a `Parser` to read the file at the specified `path`.'''

        self.cpl         = []
        self.content     = []
        self.errors      = []
        self.contentkind = []
        self.summary     = []
        self.path        = path
        print(self.path)

    def read(self):
        '''Reads the file specified at construction, and returns a dictionary
        of data from the file.'''
        # ...

                #file = DcpParse()
        file = open(self.path)
        print (file,'\t Was Successfully Opened')

        for each_line in file:
            if 'CPL Id:' in each_line:
                self.cpl=(each_line.split())
            elif 'ContentTitleText:' in each_line:
                self.content=(each_line.split())
            elif 'Errors' in each_line:
                self.errors=(each_line.split())
            elif 'ContentKind' in each_line:
                self.contentkind=(each_line.split())
            elif 'Composition summary:' in each_line:
                self.summmary=(each_line)
    # ...

def printDCP(values):
    '''Prints DCP-related key/value pairs in the specified `values` dictionary,
    or default values for unset keys.'''
    # ...
    print(values)
    print('CPL='.cpl[2]) 
    #self.content.index('ContentTitleText:')
    #self.content.pop(0)
    #print('File Name on DCP',Parser.content)
    #print('Content Kind =',contentkind[1])
    #errors.pop(0)
    #print('There are',errors[0],'Errors and',errors[2],'hints for', content)
    #if errors[0] != '0':
    #   print('could be issues')
    #else:
    #    print('This DCP appears to be OK')
        #print(summary)
    #data.close()



if __name__ == '__main__':
    for file in glob.glob("*"):
        tests = Parser(file)
        tests.read()
        #dcp_parse_gmail.main()
        #subprocess.call("dcp_parse_gmail.py", shell=True)
        #TEXT = 'some pre-test non test-driven code'
