Python 3 help!! (NOT JAVA)

1)Given four int variables that have been given values, octet1, octet2, octet3, and octet4, write a string expression whose value is the string equivalent of each these variables joined by a single period (.) So if octet1, octet2, octet3, and octet4, had the values 129, 42, 26, and 212 the expression's value would be "129.42.26.212". Alternatively, if octet1, octet2, octet3, and octet4, had the values 192, 168, 1and 44 the expression's value would be "192.168.1.44".

2)Given three int variables that have been given values, areaCode, exchange, and lastFour, write a string expression whose value is the string equivalent of each these variables joined by a single hyphen (-) So if areaCode, exchange, and lastFour, had the values 800, 555, and 1212, the expression's value would be "800-555-1212". Alternatively, if areaCode, exchange, and lastFour, had the values 212, 867 and 5309 the expression's value would be "212-867-5309".
