Now remember, in Python, indexes start at zero. 因此,为了能够查看该列表的第一个元素,我需要将其放入索引0,位置0。 So for me to be able to look at the first element of that list,I need to put in index 0, position 0. 在这里,Python告诉我第一个对象,...

Specifies arguments to pass to the Python program. Each element of the argument string that's separated by a space should be contained within quotes, for example: "args": ["--quiet","--norepeat","--port","1593"], If you want to provide different arguments per debug run, you can set...
This <Target> element defines a custom command to run the startup file for the project (identified by the StartupFile property) by using the python.exe command in a console window. The attribute definition ExecuteIn="consolepause" uses a console that waits for you to select a key to close...
