Python - a playful python for programming

Wednesday, 25 October 2006 10:45
Python is a great programming language. One of the best parts of this language is that it can be used tightly with C and C++. Python is concise and cleanly formatted. Python is portable. It can be used cross platforms.

Everything in Python is an object and multiple inheritance is allowed.

Remember: Beautiful is better than ugly.

__repr__ and __str__

So whats the difference with __repr__ vs __str__?
__repr__ is usually equal to __str__, but __repr__ is constrained by the following truth:
eval(obj.__repr__()) = obj
__str__ is used many times to pretty up or format the data within.
