script is used, Python. The CGI package is used to extract the table information contained in the Request. The script is only responsible for outputting all the results to the standard output (using print). The Cgihttprequesthandler collects these outputs, which are encapsulated in an HTTP reply and sent to the Client.For a request to the post method, its URL needs to point to a CGI script (that is, a file in Cgi-bin or ht-bin).

region, and the predictions in this area are in fact unreliable, so, to be on the safe side, we throw out the interval. Only if the result is greater than 0.394, we think is positive, less than 0.391, we think is negative, is 0.391 to 0.394, we are to be determined. The experiment shows that this method can improve the application accuracy of the model.

What this article brings to you is about how the Python function local variables are executed. On the application of Python function variables, there is a certain reference value, the need for friends can refer to, I hope to help you.

Update:Thank you for your support, thanks, and comments. I will post another piece of data processing that was previously done using Python and define a complicated new variable. It's a simple feature engineering. If Stata is used for this task, it will be a headache. In addition, this example can also be used to experience IPython Notebook (use a web version to see if the mobile version is ineffective ).
