This rule is only true for basic data types;
For example:
>>> eval(repr(1)) == 1
True
>>> eval(repr([1, 2, 3])) == [1, 2, 3]
True
>>> eval(repr({"a": 1, "b": 2, "c": 3})) == {"a": 1, "b": 2, "c": 3}
True
>>> eval(repr("foo")) == "foo"
True
I guess the key thing here is that the repr
implementation (__repr__) for str, int, float
list and dict return sensible represenations
that Python _can_ evaluate with eval(...)
