propertyName1=propertyValue1
propertyName2=propertyValue2
...

You can use a file-like object in ConfigParser.RawConfigParser.readfp defined here -> https://docs.python.org/2/library/configparser.html#ConfigParser.RawConfigParser.readfp

Define a class that overrides readline that adds a section name before the actual contents of your properties file.

I've packaged it into the class that returns a dict of all the properties defined.

import ConfigParser

class PropertiesReader(object):

    def __init__(self, properties_file_name):
        self.name = properties_file_name
        self.main_section = 'main'

        # Add dummy section on top
        self.lines = [ '[%s]\n' % self.main_section ]

        with open(properties_file_name) as f:
            self.lines.extend(f.readlines())

        # This makes sure that iterator in readfp stops
        self.lines.append('')

    def readline(self):
        return self.lines.pop(0)

    def read_properties(self):
        config = ConfigParser.RawConfigParser()

        # Without next line the property names will be lowercased
        config.optionxform = str

        config.readfp(self)
        return dict(config.items(self.main_section))

if __name__ == '__main__':
    print PropertiesReader('/path/to/file.properties').read_properties()
