Answer 1

You can use the following function, which is the modified code of @mvallebr. It respects the properties file comments, ignores empty new lines, and allows retrieving a single key value.

def getProperties(propertiesFile ="/home/memin/.config/customMemin/conf.properties", key=''):
    """
    Reads a .properties file and returns the key value pairs as dictionary.
    if key value is specified, then it will return its value alone.
    """
    with open(propertiesFile) as f:
        l = [line.strip().split("=") for line in f.readlines() if not line.startswith('#') and line.strip()]
        d = {key.strip(): value.strip() for key, value in l}

        if key:
            return d[key]
        else:
            return d
