使用python正则表达式查找重复表达式

import re
FOO = \"\"\"neighbors= {5 7 9 11 13 14 15 16 17 }\"\"\"
match = re.search(\'(neighbors\\s*=\\s*\\{\\s*(\\d+\\s*)+\\})\', FOO)
print match.group(1)

neighbors= {5 7 9 11 13 14 15 16 17 }

re.findall()

re.compile()

import re
FOO = \"\"\"neighbors= {5 7 9 11 13 14 15 16 17 }\"\"\"
COMPILE = re.compile(\'(neighbors\\s*=\\s*\\{\\s*(\\d+\\s*)+\\})\')
match = re.findall(COMPILE, FOO)
print match[0]

neighbors= {5 7 9 11 13 14 15 16 17 }

neighbors= \\{ (\\d+ )+\\}

neighbors= ?\\{ ?(\\d+ )+(\\}|\\d+\\})

neighbors\\s*=\\s*\\{[\\d\\s]+\\}
