* Don't import anything, and you can use all built-ins/methods that are otherwise available. * adding definitions: You may add additional methods and functions in support of your solution. * displaying things: _str__and_ _repr_are used by many other places in Python to get a string representation of the object. Specifically, str() calls__str_, and repr() calls_repr__, on any objects they receive as arguments. _str__often generates a human-centric representation, appropriate for a human reading what is present.__repr_often generates a Python-centric representation. The goal of_repr__is actually to have a string that could be evaluated to re-generate an identical object. In general, we would quite prefer it to look like a valid constructor call, if possible. Ultimately, we can have the same representation in str _ and repr_ if we'd like; in fact, when we didn't explicitly describe two different string representations for_str__and__repr_ to return, we can define one in terms of the other, like this def _repr_(self): return str(self) Just remember the original intent of-st-vs-rep-. It's good practice to define-init- and_repr_immediately before writing any extra methods in a Python class at a minimum, and perhaps also eq_as well. str class Line: det-init-(self, create/initialize instance variables for name, area code, number and is_active. Assume area_code is a three-digit integer with no leading 0/1; assume number is a seven-digit integer with no leading 0/1 defstr_(self): create/return a string as in this example: "703-9931530 (GMU CS)" defrepr__(self): create/return a string as in this example: "Line( 'GMU CS',_703,_9931530)" def-eq_(self, other): determine if this object (self) is equivalent to other. Two lines are considered equal if they have the same area code and same number. Return True if they are equal; return False otherwise. Examples in the test cases. area. code, number, is-active-True): constructor ofa telephone line . name, . o By providing this method, can be used to compare two lines based on area codeumber only. def activate(self): set is_active of this object to be True def deactivate(self): set is_active of this object to be False
