python 正则匹配邮箱

[passself]

感觉没有准确的匹配规则，以下是我的尝试

original_rule = r'[A-Za-z\d]{2,}([-_.][A-Za-z\d]+)*@([A-Za-z\d]+[-.])+[A-Za-z]{2,4}'
    rule = r'^([A-Za-z0-9_\-\.])+\@([A-Za-z0-9_\-\.])+\.([A-Za-z]{2,4})$'
    rule_1 = r'^[a-zA-Z0-9_-]+(\.[a-zA-Z0-9_-]+){0,4}@[a-zA-Z0-9_-]+(\.[a-zA-Z0-9_-]+){0,4}$'
    rule_2 = r'^[a-zA-Z\.]+@[a-zA-Z0-9]+\.[a-zA-Z]{3}$' #最少
    rule_3 = r'[^@]+@[^@]+\.[^@]+'
    rule_4 = r"(^[a-zA-Z0-9_.+-]+@[a-zA-Z0-9-]+\.[a-zA-Z0-9-.]+$)"
    rule_6 = r'[a-zA-Z0-9_.+-]+@[a-zA-Z0-9-]+\.[a-zA-Z0-9-.]+'
    rule_5 = r"([-a-zA-Z0-9.`?{}]+@\w+\.\w+)"   
    rule_7 = r'^[a-zA-Z0-9.+_-]+@[a-zA-Z0-9._-]+\.[a-zA-Z]+$'

无法检验 [e-mail] 和 [e-mail] 是错误邮箱
