Python program related to the implementation of what is, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain in detail for you, people with this need can come to learn, I hope you can gain something.

Mainly to track the implementation of a relatively simple Python program, to briefly discuss the basic framework and structure of Python implementation of some related content introduction.

To execute the Python program, the function is very simple: add it from 1 to 10 and then print it.

# test program sum = 0 for i in range (1,11): sumsum = sum + i print sum

If you want to debug Python with VS 2005 under Windows, you can set Startup Project to Python so that you can launch Python directly through F5. Right-click the Project Python and select Properties. In the dialog box

Configuration Properties- > Debugging

Next, set Command Arguments to-d test.py. Where test.py is the name of the program we want to debug. -d means to turn on the debug switch and you can see additional debugging information.

All right, after setting up, you can press F10 directly to track the execution of the program step by step.

First of all, F10, starting the program, you can see that there is nothing in the main function of Python, just simply calling Py_Main. As the name implies, Py_Main is naturally the main function, which is divided into several parts:

Analyze command line and environment variables

Initialize by calling Py_Initialize

Enter different execution modes according to the contents of the command line

If (command) {sts = PyRun_SimpleStringFlags (command, & cf)! = 0; free (command);} else if (module) {sts = RunModule (module); free (module);} else {if (filename = NULL & & stdin_is_interactive) {RunStartupFile (& cf);} / * XXX * / sts = PyRun_AnyFileExFlags (fp, filename = NULL? ": filename, filename! = NULL, & cf)! = 0 } is it helpful for you to read the above content?
