Python 2.4 adds the command line switch -m to allow modules to be located using the Python module namespace for execution as scripts. The motivating examples were standard library modules such as pdb and profile, and the Python 2.4 implementation is fine for this limited purpose. So you can specify any module in Python's search path this way ...
In Python 2.2 or later in the 2.x line, there is no difference for integers unless you perform a from __future__ import division, which causes Python 2.x to adopt the 3.x behavior. Regardless of the future import, 5.0 // 2 will return 2.0 since that's the floor division result of the operation.

Mar 21, 2010 · There is no bitwise negation in Python (just the bitwise inverse operator ~ - but that is not equivalent to not). See also 6.6. Unary arithmetic and bitwise/binary operations and 6.7. Binary arithmetic operations. The logical operators (like in many other languages) have the advantage that these are short-circuited.
Here is the logical equivalent code in Python. This function takes a Python object and optional parameters for slicing and returns the start, stop, step, and slice length for the requested slice. def py_slice_get_indices_ex(obj, start=None, stop=None, step=None): length = len(obj) if step is None: step = 1.
Jan 30, 2011 · In Python, += is sugar coating for the __iadd__ special method, or __add__ or __radd__ if __iadd__ isn't present. The __iadd__ method of a class can do anything it wants. The list object implements it and uses it to iterate over an iterable object appending each element to itself in the same way that the list's extend method does.
Dec 27, 2008 · As already answered, yes, there is a ternary operator in Python: <expression 1> if <condition> else <expression 2>. In many cases <expression 1> is also used as Boolean evaluated <condition>. Then you can use short-circuit evaluation. a = 0.
