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）答案

【问题描述】：

我一直在努力解决在 VSCode 中我想在调试控制台中评估多行 Python 代码而不必单独选择每一行并将其发送到调试控制台的问题。但是，当我一次选择多行并想在调试控制台中评估它们时，现有的缩进会被复制到调试控制台并在那里导致缩进错误。从那以后，我已经能够将问题缩小到我确定这主要发生在调试类方法时。下面给出了一个最小的示例。

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

如果我在a = 3 行设置断点，然后在调试期间到达该断点，然后我选择行a = 3 直到并包括c = a + b 并希望在调试控制台中评估所有3 行，这导致将行复制到调试控制台，如下所示：

a = 3
        b = 4
        c = a + b

这会导致以下错误：

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
      ^
SyntaxError: invalid syntax

During handling of the above exception, another exception occurred:

这是一个非常烦人的问题。任何解决方案将不胜感激。

【解决方案1】：

你确实复制了第二行的缩进。

当您从a 复制到a+b 时，您可以按Alt + Shift 来避免这种情况。
