I'm running a Conda environment on VSCode and when I Shift-Enter to run main.py , a new Python terminal opens and runs the script, but functions are executing without being called and I'm getting a :

SyntaxError: 'return' outside function 

Despite the indentation being seemingly fine.

import math

def h(x):
    if x==0:
        return 1
    else:
        return 2*math.sin(x)/x - 1

The above returns:

CodePudding user response：

You have executed the command of Run Selection/Line in Python Terminal with the shortcut of Shift Enter. You can select the command of Run Python File in Terminal which is above it.

CodePudding user response：

Shift Enter is keybindings for Run Selection/Line in Python Terminal, so if you put cursor in the line of return 2*math.sin(x)/x - 1, it will throw errors:

If you want to enter interactive mode then run the function h(x), please

1. type python in integrated Termial;
2. import filename. In my case, it's a.py so i import a;
3. call the function: a.h(any number)
4. exit interactive mode;

Or you can get result directly by adding print(h(any number)), then clicking the triangle button in top right corner to run python file in integrated Terminal. Get the same result:

CodePudding user response：

run the entire code in python as opposed to the last line.

if you want to run entire scripts:

python3 xxxx.py
