Expected behaviour

When I highlight Python code and run selection I expect it to run if it is syntactically correct.

Actual behaviour

I’m receiving indentation errors in specific scenarios for code that is syntactically correct.

Steps to reproduce:

[NOTE: Self-contained, minimal reproducing code samples are extremely helpful and will expedite addressing your issue]

Run selection on the following code and the following error(s) will occur

if False:
    print("if")
elif True:
    print("elif")
else:
    print("else")

if False:
...     print("if")
... 
>>> elif True:
  File "<stdin>", line 1
    elif True:
    ^
SyntaxError: invalid syntax
>>>     print("elif")
  File "<stdin>", line 1
    print("elif")
    ^
IndentationError: unexpected indent
>>> else:
  File "<stdin>", line 1
    else:
    ^
SyntaxError: invalid syntax
>>>     print("else")
  File "<stdin>", line 1
    print("else")
    ^
IndentationError: unexpected indent
>>>

If I copy/paste the same code into the Python interactive window it will run without error.

This should be fixed on our newest release, version 2021.1.502429796, but if you’re still seeing this let us now 😊

Nice. It helps a lot.
