if(validform().form()) {
//Through form validation, write your own code below./ / form validation is successfully executed.Var url = path + "/GroupCustomer.do? Action=toAddAndUpdate& id=" +gRoupId;$("#editWin").Window ("close");GetVpnInfoData ();$.ajax ({Method:'get',Async:faLSE,Data: $("#data_form").Seri...
The first is to set up the running mode of Python.
That is, our common line, /usr/bin/python3, or /usr/bin/python!
Mainly used to specify the mode of operation.
Python3 xxx.py or Python xxx.py is equivalent to our input in the terminal.
Specifying this line allows us to turn it into an executable program that first gives permission Chmod 777 xxx.py to the terminal
Then you can run the program by double clicking.
Remember that you have to put it in the first line.
#coding:utf-8
#!/usr/bin/python
while True:
print('yes')
