Question

我正在使用Python 3（3.5.3）在Thonny中调试python脚本。我在Raspberry Pi ZeroW上使用Linux raspberrypi 4.9.59+＃1047运行它。我通过Wi-Fi通过realVNC远程连接。

Python脚本有一些初始化代码，可以将一些变量设置为默认值。该脚本按需运行;没有错误。

我正在添加从文件中读取一组配置参数以初始化变量的功能。

config = {}
config_dir = os.path.dirname(os.path.abspath(__file__))
config_file = config_dir + "/temps.conf"
with open(config_file, "r") as fh:
    exec(fh.read()+"\n", config)
    fh.close()

只需开始调试脚本（即，不是单行代码解释，只需ctrl + F5）会导致回溯：

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/thonny/shared/thonny/ast_utils.py", line 178, in _mark_text_ranges_rec
    tokens = _mark_end_and_return_child_tokens(node, tokens, prelim_end_lineno, prelim_end_col_offset)
  File "/usr/lib/python3/dist-packages/thonny/shared/thonny/ast_utils.py", line 263, in _mark_end_and_return_child_tokens
    _strip_trailing_junk_from_expressions(tokens)
  File "/usr/lib/python3/dist-packages/thonny/shared/thonny/ast_utils.py", line 202, in _strip_trailing_junk_from_expressions
    while (tokens[-1].type not in (token.RBRACE, token.RPAR, token.RSQB,
"IndexError: list index out of range"

通过注释掉新的代码块并一次取消注释一个语句，我已经将导致错误的语句缩小到＆＃34; exec（...）＆＃34;线。同样，错误发生在任何语句运行之前。虽然发生了错误，但Thonny允许我继续执行脚本。如果我单步执行该程序，我期待exec语句失败。实际上，代码执行得很好。读取配置文件并将其加载到我的配置数组中。然后我可以在我的Python脚本的其余部分中检索参数。

因此，看起来这个回溯更多的是警告而不是严重错误。我可以忽略它，但我希望这是试图告诉我一些事情 - 哪里有烟，哪里可能是闷烧的火。我想了解造成这个问题的原因，以便我可以消除它。

感谢您的见解！

这确实是Thonny的一个错误。我创建了一个问题：https://bitbucket.org/plas/thonny/issues/396/exec-causes-range-marker-to-crash
