Python string builder ?

building_a_string.py

class ConfigurationFile():
    def __init__(self, config1, config2):
        self._config1 = config1
        self._config2 = config2

    def output_file(self):
        print(
            "configuration-group={\n"
            "    config1=\"" + self._config1 + "\"\n"
            "    config2=\"" + self._config2 + "\"\n"
            "}"
        )

myConfigFile = ConfigurationFile('value of config 1', 'value of config 2')
myConfigFile.output_file()

If you're using python 3.6 ; You could use f-strings

>>> name = 'Fred'
>>> age = 42
>>> f'He said his name is {name} and he is {age} years old.'
He said his name is Fred and he is 42 years old.

Thanks @erozqba and @ventilooo for the hints!

I'll check that out! :)
