    ...operators, and so on. Python's Strengths Syntactically, Python code looks like executable pseudo code. Program development using Python is 5-10 times faster than using C/C++, and 3-5 times faster than using Java. In many cases, a prototype of an application can be written in Python without writing any C/C++/Java code. Often, the prototype is sufficiently functional and performs well enough to be delivered as the final product, saving considerable development time. Other times, t...

    ...OPERATOR ... def nop(self, operator, left, right): return self.factory.createNumericOperator(operator, left, right) This class can go into the grammar definition file.

  • Notes

    ...== is the Boolean inverse of !=, or that < is the Boolean inverse of >=. This makes it possible to define types with partial orderings. Classes or types that want to implement (in)equality tests but not the ordering operators (i.e. unordered types) should implement == and !=, and raise an error for the ordering operators. It is possible to define types whose rich comparison results are not Boolean; e.g. a matrix type might want to return a matrix of bits for A < B, giving elementwise c...

  • Python 2.0

    ...operators in order to implement the in-place behavior; the not-in-place behavior is used automatically as a fallback when an object doesn't implement the in-place behavior. For classes, the method name is derived from the method name for the corresponding not-in-place operator by inserting an 'i' in front of the name, e.g. __iadd__ implements in-place __add__. Augmented assignment was implemented by Thomas Wouters. List Comprehensions This is a flexible new notation for lists w...
