如果value包含这些字母,那么

import re

value = "abcde"
pattern = re.compile("[abced]")
match = pattern.search(value)
if match:
    print("匹配成功")
else:
    print("匹配失败")

import re

value = "abcde"
pattern = re.compile("abc")
match = pattern.search(value)
if match:
    print("匹配成功")
else:
    print("匹配失败")

import re

value = "abcde"
pattern = re.compile("a.c")
match = pattern.search(value)
if match:
    print("匹配成功")
else:
    print("匹配失败")
