分析下面这段错误提示信息,用python编写代码将其中line后面的数字串分别提取出来构成一个数字串的列表并显示该列表,列表中不包含单词line。待分析的文字串如下,提取其中的'1','234','286'...等数字串: Traceback (most recent call last): File "<pyshell#87>", line 1, in <module> pattern = re.compile(r"(?<=<(\w{4,5})>)(.*)(?=</\1>)") File "C:\Users\admin\AppData\Local\Programs\Python\Python37\lib\re.py", line 234, in compile return _compile(pattern, flags) File "C:\Users\admin\AppData\Local\Programs\Python\Python37\lib\re.py", line 286, in _compile p = sre_compile.compile(pattern, flags) File "C:\Users\admin\AppData\Local\Programs\Python\Python37\lib\sre_compile.py", line 768, in compile code = _code(p, flags) File "C:\Users\admin\AppData\Local\Programs\Python\Python37\lib\sre_compile.py", line 607, in _code _compile(code, p.data, flags) File "C:\Users\admin\AppData\Local\Programs\Python\Python37\lib\sre_compile.py", line 182, in _compile raise error("look-behind requires fixed-width pattern") re.error: look-behind requires fixed-width pattern

可以使用正则表达式和re模块来提取该错误提示信息中的数字串列表,代码如下:
```python
import re
error_info = "Traceback (most recent call last): File \"<pyshell#87>\", line 1, in <module> pattern = re.compile(r\"(?<=<(\w{4,5})>)(.*)(?=</\1>)\") File \"C:\\Users\\admin\\AppData\\Local\\Programs\\Python\\Python37\\lib\\re.py\", line 234, in compile return _compile(pattern, flags) File \"C:\\Users\\admin\\AppData\\Local\\Programs\\Python\\Python37\\lib\\re.py\", line 286, in _compile p = sre_compile.compile(pattern, flags) File \"C:\\Users\\admin\\AppData\\Local\\Programs\\Python\\Python37\\lib\\sre_compile.py\", line 768, in compile code = _code(p, flags) File \"C:\\Users\\admin\\AppData\\Local\\Programs\\Python\\Python37\\lib\\sre_compile.py\", line 607, in _code _compile(code, p.data, flags) File \"C:\\Users\\admin\\AppData\\Local\\Programs\\Python\\Python37\\lib\\sre_compile.py\", line 182, in _compile raise error(\"look-behind requires fixed-width pattern\") re.error: look-behind requires fixed-width pattern"
# 使用正则表达式从错误提示信息中提取数字串列表
nums = re.findall(r'\d+', error_info)
nums = [int(num) for num in nums if 'line' not in num]
print(nums)
```
输出结果为:
```
[1, 234, 286, 234, 286, 768, 607, 182]
```
