Good, some other sources for learning:

Here's some code to get you started  (version 3.4.0):

"""
convert

set interfaces ge-0/0/0 unit 0 family inet address 10.17.10.1/24

to

interfaces {
    ge-2/0/5 {
        unit 0 {
            family inet {
                address 10.17.10.1/24;
            }
        }
    }
}
"""

class interface():
    attribute_name_list = ("ge", "unit", "family", "address")
    def __init__(self, ge, unit, family, address):
        self.ge = ge
        self.unit = unit
        self.family = family
        self.address = address

def convert(interface_list, indent=4):
    indentation = 0
    return_list = list()
    return_list.append(" " * indentation + "interfaces {")
    for interface in interface_list:
        for attribute_name in interface.attribute_name_list:
            indentation += indent
            text = "%s %s {" % (attribute_name, getattr(interface,
attribute_name))
            return_list.append(" " * indentation + text)
        while indentation > indent:
            indentation -= indent
            return_list.append(" " * indentation + "}")
        indentation -= indent
    return_list.append("}")
    return "\n".join(return_list)

if __name__ == "__main__":
    interface1 = interface("0/0/0", "0", "inet", "10.17.10.1/24")
    interface2 = interface("2/0/5", "0", "inet", "11.18.10.1/24")
    print(convert((interface1, interface2, )))
