[英]Looking for a regular expression to match following
string = '***All Done***, ***Execution Success 5664 for $**$ files***'
re pattern = ([\w+].*[\$\*\*]\$.*[\w+]|[\w+])
output i'm getting: 'All Done***, ***Execution Success for $**$ files'
预期的输出: All Done Execution Success 5664 for $**$ files
应该只获取字母数字字符和$\\*\\*$
。 其余所有应清除。 任何帮助,将不胜感激。 如果在字符串上未找到$\\*\\*$
,则它应返回: All Done Execution Success 5664 for files
。
这似乎适用于您提供的示例(Python 3.6):
import re
strings = [
'***All Done***, ***Execution Success 5664 for $**$ files***',
'Error not ** found. Restore $**$ again **'
]
pattern = "\w+|\$\*\*\$"
cpattern = re.compile(pattern)
for string in strings:
print(" ".join(cpattern.findall(string)))
输出:
All Done Execution Success 5664 for $**$ files Error not found Restore $**$ again
