I run a python script in vscode but the value in the output tab does not match the value in the terminal

Environment data

• VS Code version: 1.38
• Extension version (available under the Extensions sidebar): XXX
• OS and version: windows 8
• Python3 version (& distribution if applicable, e.g. Anaconda): 3.6.8
• Type of virtual environment used (N/A | venv | virtualenv | conda | …): XXX
• Relevant/affected Python packages and their versions: XXX
• Jedi or Language Server? (i.e. what is "python.jediEnabled" set to; more info #3977): XXX

Expected behaviour

terminal and output must print 1.5

Actual behaviour

Output tab prints a 0 and terminal value prints a one

Steps to reproduce:

Run this code

class Solution:
    def lt(self, p, q, h,start):
           if(q==0 and h ==start):
                   if(0<=p<=1):
                           return p
                   if(p>1):
                           return 1
           if(q<0 or p<0):
                return 0
           a=self.lt((p-1)/2,q-1,h,start) 
           b= self.lt((p-1)/2,q-1,h,start+1)
           return a+b

a=Solution()
print(a.lt(6,2,1,0))

Logs

Output for Python in the Output panel (View→Output, change the drop-down the upper-right of the Output panel to Python)

XXX

Output from Console under the Developer Tools panel (toggle Developer Tools on under Help; turn on source maps to make any tracebacks be useful by running Enable source map support for extension debugging)

First, please note that the Code Runner extension isn’t related to the Python extension for VS Code.

It looks like you have multiple versions of Python installed, so if you run python in a terminal window without an active virtual environment it will start the interpreter for Python 2.7, and to get Python 3.X you would have to run python3.

Manually running python <yourfile.py> returns 0, while running python3 <yourfile.py returns 1.5.

If you modify the code-runner.executorMap setting for the Code Runner extension you will see that it calls python -u for Python files and not python3 -u.

If you look at the Configuration section for the Code Runner extension, they mention this custom parameter:

$pythonPath: The path of Python interpreter (set by Python: Select Interpreter command)

which you could use in code-runner.executorMap.
