Question: I am from Java programming, new to Python. Should I consider integer, float and string literals also as object of python programming? 

eg: `2`, `4.3`, `'stackoveflow'`

Answer: 
[Everything in python is an object.](http://docs.python.org/reference/datamodel.html) Even functions and plain numbers/booleans.

This has quite some advantages, for example, you can easily subclass a type such as `str` or `unicode` if you need a custom type with the default behaviour but additional features (often done in template engines to mark strings as HTML-safe).  

Another more common thing is the `join()` method on strings. While most languages have such a methods on arrays, Python has it as a string method which is used like this, allowing you to pass *any* iterable/sequence to it: `', '.join(some_iterable)`
Yes, every value is an object in Python. For example:

```
>>> dir(3)
['__abs__', '__add__', '__and__', '__bool__', '__ceil__', '__class__', '__delattr__', '__divmod__', '__doc__', '__eq__', '__float__', '__floor__', '__floordiv__', '__format__', '__ge__', '__getattribute__', '__getnewargs__', '__gt__', '__hash__', '__index__', '__init__', '__int__', '__invert__', '__le__', '__lshift__', '__lt__', '__mod__', '__mul__', '__ne__', '__neg__', '__new__', '__or__', '__pos__', '__pow__', '__radd__', '__rand__', '__rdivmod__', '__reduce__', '__reduce_ex__', '__repr__', '__rfloordiv__', '__rlshift__', '__rmod__', '__rmul__', '__ror__', '__round__', '__rpow__', '__rrshift__', '__rshift__', '__rsub__', '__rtruediv__', '__rxor__', '__setattr__', '__sizeof__', '__str__', '__sub__', '__subclasshook__', '__truediv__', '__trunc__', '__xor__', 'bit_length', 'conjugate', 'denominator', 'from_bytes', 'imag', 'numerator', 'real', 'to_bytes']
>>> (3).__str__()
'3'

```
