python使用正则表达式 \d\d\d-\d\d\d-\d\d\d,来匹配前面isPhoneNumber()函数匹配的同样文本:3个数字、一个短横线、3个数字、一个短横线、4个数字 所有其他字符串都不能匹配 \d\d\d-\d\d\d-\d\d\d 正则表达式 但是 正则表达式可以复杂得多。 例如:在一个模式后加上花括号包围的3({3}),就是...
phoneMatch = phoneNumRegex.search('My number is415-555-4242') print('Phone number found :'+phoneMatch.group()) 输出: //Phonenumber found :415-555-4242 1. 2. 3. 4. 5. 总结一下:在 Python中使用正则表达式有几个步骤,但每一步都相当简单。 1.用 import re 导入正则表达式模块。 2.用 re...
在正则表达式中,我们可以使用括号来定义分组,并通过捕获组来提取匹配结果中的特定部分。 python import re # 定义一个要匹配的字符串 text = "My phone number is 123-456-7890 and my friend's number is 987-654-3210." # 定义一个正则表达式模式,匹配形如"xxx-xxx-xxxx"的电话号码,并使用括号捕获号码...

2.1Python例子 假设我们有一个字符串列表,每个字符串包含一个email地址,我们想要从中提取出所有的email地址,先用regex101写好正则表达式。 在这里插入图片描述 我们可以使用Python内置的re模块和正则表达式来实现: import re # 定义正则表达式 pattern = r'\b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Z...
REGEX is a module used for regular expression matching in the Python programming language. In fact, REGEX is actually just short for regular expressions, which refer to the pattern of characters used in a string. This concept can apply to simple words, phone numbers, email addresses, or any ...
以下是一个使用Python的re模块通过正则表达式提取子字符串的示例: 代码语言:txt 复制 import re text = "Hello, my email is example@example.com and my phone number is 123-456-7890." email_pattern = r'\b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Z|a-z]{2,}\b' phone_pattern = ...
