Explain the relationship between `__str__`, `__repr__`, `__bytes__` (`__unicode__`) in both Python 3 and 2.
"""
Conclusions:
1. `print(o)` equals to `print(str(o))`
2. `str(o)` will use `__repr__` if `__str__` not exist
3. `repr(o)` only uses `__repr__`
4. `unicode(o)` will use `unicode(__str__())` if `__unicode__` not exist
