Reply content:Let me correct and comment. > 1. Print is no longer a statement, but a function, such as the original print ' ABC ' is now print (' abc ') However, python2.6+ can use the from __future__ import print_function to achieve the same functionality > 2. In Python 3, there is no old-fashioned class, only the new class, which means no more like this class Foobar (object): Pass explicitly sub-class obj

Ython is a very cool language, because very few Python code can do a lot of things in a short time, and Python can easily support multitasking and multiprocessing.Python's critics claim that Python performance is inefficient and slow to perform, but it is not: try the following 6 tips to speed up your

corresponding to the pycodeobject and stack frame corresponding f_globals build Pyfunctionobject object, and then through Store_ The name Directive associates the Pyfunctionobject object with the function name F and stores it in the local namespace. The corresponding pycodeobject of function f can be obtained and viewed by co.co_consts[0].inch[1]: Source = open (' func.py ').

Python day 9 (6) debugging, pythonday The probability that the program can be written and run normally at a time is very small, basically no more than 1%. There will always be various bugs to be corrected. Some bugs are very simple. You can see the error information. Some bugs are very complicated. We need to know which variables are correct and which variables are wrong when an error occurs. Therefore, A c

to complete a single step, but to describe the behavior of something in the whole process of solving the problem.For example, the process-oriented design is the first step in the analysis of the problem: 1, start the game, 2, Sunspot first go, 3, draw the screen, 4, Judge Win and lose, 5, turn to white son, 6, draw the screen, 7, Judge Win and lose, 8, return step 2,9, output the final result. The problem

raise statement because the purpose of capturing the error is simply to record, because the current function does not knowWhat to do with the error, so throwing up is a good way to end up with the top-level caller.Debugging:1. One method is simple and rough, print directly with print ().2. Assert that any use of print () to assist viewing can be overridden by an assertion (assert).3.logging, replace print () with logging is the third way, logging can
