Running a loop/multiple lines in vs code python debug console

Question

How do I run a simple loop in VS Code’s python debug console? When I try to enter the following:

for el in dataset:

It gives me the error below. I seem to be able to enter variable names, but not multi-line commands like I can in the normal python REPL.

Traceback (most recent call last):
  File "/home/tensorflow/.local/lib/python3.6/site-packages/debugpy/_vendored/pydevd/_pydevd_bundle/pydevd_vars.py", line 416, in evaluate_expression
    compiled = compile(_expression_to_evaluate(expression), '<string>', 'eval')
  File "<string>", line 1
    for el in dataset:
      ^
SyntaxError: invalid syntax

During handling of the above exception, another exception occurred:

Answer 1

You have 2 options:

Write the command in a new editor window, then simply copy and paste the code in the debug console and press Enter
Write the command directly in the debug console. When you want to enter a new line, press Shift+Enter. When the command is complete, execute with Enter

Another option:

2.1. Write the command directly in the debug console. Type {} at the end of current line, then press shift+enter. After complete writing all lines, press enter to execute.

for i in [1,2,3]: {'''press shift+enter here'''}
for i in [1,2,3]: {
    print(i)  #press enter here
}

I found this reference https://youtu.be/p8zMXKFlkqk?t=50 very helpful in running a function on variables existing in debug mode
