Visual Studio Code - python 控制台

Question

I'm using visual studio code with standard python extension, my issue is that when I run the code the python interpreter instantly closes right after and I only see the output which means that if I create some data structure I have to create it every single time. Is it possible to leave the console open after running the code and maybe running multiple files in the same python interpreter instance?

Answer 1

When you run a program, it runs until it ends. Then it closes. If you want it to stay live longer, you can make a program which does not stop until told so, eg

while True:
    something = raw_input('Write something: ')
    print('You wrote: %s' % something)
    if something == 'bye':
        print 'bye.'
        break

This will run until user writes "bye".

I used to use spyder which is entirely doing what you want (probably like PyCharm)... Then I briefly tried VS Code, and it is quite easy to make it behave that way too.

First make sure you have an integrated terminal open (or do Ctrl+`, or View > Integrated Terminal), then in that terminal launch ipython . Now, when you use the commands from Don Jayamanne's Python extension (Ctrl+Shift+P to oppen commands palette):

• "Run Python File in terminal"
• "Run select/line in Terminal"

It will run the line inside the ipython console directly. So running the entire fail will call python module.py inside ipython, and thus fails .

So to make this work simply create settings to map which command is executed when "Run select/line in terminal":

• Open Language specific settings (Shift+Ctrl+P, search "Configure Language specific Settings...")
• Pick up Python
• Now I would suggest to make change only in your workspace settings (top-right tab) to keep default behaviour in other cases so add in WORKSPACE SETTINGS :

(keep in mind it is just a simple/stupid workaround)

{
    "python.pythonPath": "run"
}

Now when runing whole file, it will use ipython function run within the ipython terminal that we launched, thus keeping all your workspace variables . Also, if you run some line of code with "Run Select/Line in Terminal", the ipython session of that terminal keep all variables.

This allows live debugging, without actually going in the debug mode.

I'm quite late to this conversation, but a workaround I use is to put a pass statement at the end of my file, then add a breakpoint to it. I then run it in the debugger and can access all of the variables etc.

This allows most of the functionality that I used to use in the PyCharm python terminal, such as exploring data structures, checking out methods, etc. Just remember that, if you want to make a multi-line statement (eg. for a loop), you need to use Shift-Enter to go to the next line otherwise it'll try to evaluate it immediately.
