我需要将以下多行文本中AAA和BBB之间的整个文本（不包括那些）替换为空白。我尝试了此模式=> 'This form.*[^Accuracy.]Accuracy.'但它只能捕获到第一个'Accuracy.'我试图做一个贪婪的捕获，但无法获得正确的模式。请帮助。

import re
haystack='''Other needs and/or restrictions:
Telephone visit on 11/16 @ 3:50 PM 
AAA This form has been electronically signed. 
Check for Accuracy. XXX authorized by Dr Zhivago (M.D.) 
This form contains your private health information that 
you may choose to release to another party; 
please review for Accuracy. 
BBB
'''
pattern = 'This form.*[^Accuracy\.]Accuracy\.'
p = re.compile(pattern, re.MULTILINE)
match = p.search(haystack)
if match != None:
    haystack = re.sub(pattern,'',haystack,re.MULTILINE)
    print(haystack)

下面是捕获AAA和BBB之间的所有字符串：

import re

text = '''Other needs and/or restrictions:
Telephone visit on 11/16 @ 3:50 PM 
AAA This form has been electronically signed. 
Check for Accuracy. XXX authorized by Dr Zhivago (M.D.) 
This form contains your private health information that 
you may choose to release to another party; 
please review for Accuracy. 
BBB'''

pattern = re.compile(r'AAA(.*?)BBB', re.DOTALL)
matches = pattern.findall(text)

for match in matches:
    print(match.strip())
