Question

我有跟踪消息，如：

_str = ['exec(\'g.\'+option_val+\'=\'+option_val+\'()\')\n', '  File "<string>", line 1, in <module>\n', '  File "/home/nazariy/git/investment-tools/app/core/utilities/dbmonet.py", line 16, in __init__\n    raise ValueError(\'Could not connect to the MonetDB database\')\n', 'ValueError: Could not connect to the MonetDB database\n']

我正在努力取代每一个\＆＃39;出现＆＃34;在Pycharm：

_str = [str_.replace("\'",'"') for str_ in _str]

以上不起作用，它因某种原因拆分每一个字符。但上面的确适用于jupyter qtconsole ......

我还尝试在Pycharm中转义转义字符：

_str = [str_.replace("\\'",'"') for str_ in _str]

也行不通......

任何想法？感谢

修改

以下是生成回溯的代码段：

import sys, traceback
exc_type, exc_value, exc_traceback = sys.exc_info()
pretty_traceback = repr(traceback.format_exception(exc_type, exc_value, exc_traceback))
#print("---- All the items ---")
#for i, x in enumerate(pretty_traceback): print(str(i) + ": "+(x))
print("------------------------- before pretty -----------------------")
pretty_traceback = [i.replace(r"\'", '"') for i in pretty_traceback]
print(pretty_traceback)
print("------------------------ pretty escape -------------------")
pretty_traceback = [i.replace(r"\n", "") for i in pretty_traceback]
print(pretty_traceback)
print("------------------------ pretty replace -------------------")
pretty_traceback = ["<p>"+_str+"</p>"       for _str in pretty_traceback]
print(pretty_traceback)

使用Regex

<强>实施例

import re
_str = ['exec(\'g.\'+option_val+\'=\'+option_val+\'()\')\n', '  File "<string>", line 1, in <module>\n', '  File "/home/nazariy/git/investment-tools/app/core/utilities/dbmonet.py", line 16, in __init__\n    raise ValueError(\'Could not connect to the MonetDB database\')\n', 'ValueError: Could not connect to the MonetDB database\n']
_str = [re.sub(r"\'", '"', i) for i in _str]
print(_str)

<强>输出：

['exec("g."+option_val+"="+option_val+"()")\n', '  File "<string>", line 1, in <module>\n', '  File "/home/nazariy/git/investment-tools/app/core/utilities/dbmonet.py", line 16, in __init__\n    raise ValueError("Could not connect to the MonetDB database")\n', 'ValueError: Could not connect to the MonetDB database\n']

PyCharm字符串替换＆＃34; \＆＃39;＆＃34;
