vscode：在调试控制台中评估多个选定的行会导致缩进错误（使用 python 类）

Question

I have been struggling for a while with the problem that in VSCode I would like to evaluate multiple lines of Python code in the debug console without having to select each line individually and send it to the debug console. However, when I select multiple lines at once and want to evaluate them in the debug console, the existing indentations are copied to the debug console and cause an indentation error there. I have since been able to narrow down the problem to the point where I have determined that this occurs mainly when debugging class methods. A minimal example is given below.

class MyClass:
    def __init__(self):
        pass
    def run(self):
        a = 3
        b = 4
        c = a + b
MyClass().run()
  

If I set a breakpoint at line a = 3 , which is then reached during debugging, and I then select lines a = 3 up to and including c = a + b and want to have all 3 lines evaluated in the debug console, this results in the lines being copied to the debug console as follows:

a = 3
        b = 4
        c = a + b

Which causes the following error:

Traceback (most recent call last):
  File "/home/lukas/.vscode/extensions/ms-python.python-2021.9.1230869389/pythonFiles/lib/python/debugpy/_vendored/pydevd/_pydevd_bundle/pydevd_vars.py", line 419, in evaluate_expression
    compiled = compile(_expression_to_evaluate(expression), '<string>', 'eval')
  File "<string>", line 1
    a = 3
      ^

During handling of the above exception, another exception occurred:

IndentationError: unexpected indent

This is a very annoying problem. Any solution would be greatly appreciated.

Answer 1

You really have copied the indent from the second line.

You can press Alt + Shift when you copy from a to a+b to avoid this.
