import re
import sys

s='{通配符}你好，今天开学了{通配符},你好'
print("s", s)
a1 = re.compile(r'\{.*?\}' )
d = a1.sub('',s)
print("d",d)

-----------------------------------------------------------------------------
a1 = re.compile(r'\{[^}]*\}' )
d = a1.sub('',s)
print("d",d)

-----------------------------------------------------------------------------
text = re.sub(r'{[^{}]*}', '', s)  # 去除包含在{}中的内容
print('text',text)

-----------------------------------------------------------------------------
sub_text=r'\{.*?\}' 
pattern=re.compile(sub_text)
result=re.sub(pattern, '', s).strip()
print()
