可以借助正则表达式校验某个字符串是否是合规的电子邮箱。对于邮箱的正则表达式有严格的模式,如:^[a-zA-Z0-9_+&*-]+(?:\\.[a-zA-Z0-9_+&*-]+)*@(?:[a-zA-Z0-9-]+\\.)+[a-zA-Z]{2,7}$对应的Python实现如下: 代码语言:javascript 复制 importre;REGEX_PATTERN="^[a-zA-Z0-9_+&*-]...

This code uses regex pattern matching. To do this, first You need to define a regular expression pattern that will match a valid email id. A email id has a name, domain name & gTLD (like: .com , .org, .net etc.,) Example:abc@officetricks.com ...
本文针对有一点正则基础的同学,如果你对正则一无所知,请移步“正则表达式30分钟入门教程”学习。 要验证一个字符串是否为邮箱的话,首先要了解邮箱账号的格式。我尝试过在网上找出一个标准的格式,但是很遗憾我没有找到。我也尝试使用RFC标准来判断邮箱的格式,但是也没有结果。网上些博客说不应该使用RFC标准来...

A regular expression pattern can permit the full stop sign (.) and disallow the plus sign (+) in an email address. This means email addresses with the plus sign will not pass the regular expression. So, they’ll returnfalse, even if it’s valid. The pattern we’ll define in this sec...
