Python 正则表达式整个字符串匹配数字之间

可以使用regexp (?:\d|\b){0}(?:\d|\b)将目标单词与单词边界或其两侧的数字进行匹配.

import re

def findWholeWord(w):
    return re.compile(r'(?:\d|\b){0}(?:\d|\b)'.format(w), flags=re.I).search

for s in [
    'this is Thomas again',
    'this is,Thomas again',
    'this is,Thomas, again',
    'this is.Thomas, again',
    'this is ?Thomas again',
    'this is 9Thomas, again',
    'this is9Thomas again',
    'this is Thomas36 again',
    'this is -Thomas- again',
    'athomas is no match',
    'thomason no match']:
    print("match >" if findWholeWord('thomas')(s) else "*no match* >", s)

Output:个

match > this is Thomas again
match > this is,Thomas again
match > this is,Thomas, again
match > this is.Thomas, again
match > this is ?Thomas again
match > this is 9Thomas, again
match > this is9Thomas again
match > this is Thomas36 again
match > this is -Thomas- again
*no match* > athomas is no match
*no match* > thomason no match

如果您想对多个输入或在循环中重复使用相同的目标单词，那么您可以将findWholeWord()调用赋给一个变量，然后调用它.

matcher = findWholeWord('thomas')
print(matcher('this is Thomas again'))
print(matcher('this is,Thomas again'))
