If you are using CPython then optimization usually goes by re-implementing bottleneck-code in C/C++.Ĭogapp also works nice with code in other languages, XML or JSON. Python interpreter still needs to parse the generated code. As it is a repetitive task, macros can come into action here. For example: suppose for every month, a report is to be created for all the teachers of a school. When a macro is created, the whole mouse clicks, and the keystrokes get recorded. The hygiene problem can extend beyond variable bindings. Please note that generating code like this is not proper way to optimize for performance. A macro is a set of actions that we can run as many times as required to perform a particular task. The variable a declared in the top scope is shadowed by the a variable in the macro, which introduces a new scope.As a result, a is never altered by the execution of the program, as the output of the compiled program shows: a is now 4, b is now 9 Standard library function redefinition. I have added release_git_version code bit to show usefulness, as other answers try to dismiss this question as nonsense. One of the goals of Pythons weak reference implementation is to allow any type to participate in the weak reference mechanism without incurring the overhead on performance-critical objects (such as numbers). Here is an example macro_test.py: #define english ] If you do not want your writing to be edited mercilessly and redistributed at will, then do not submit it here.There is very nice solution in form of python module, the cogapp module.
