在Python中，re模块提供了对正则表达式的支持，通过使用search()和match()方法，我们可以进行字符串的匹配和搜索。2. search()方法的使用search()方法用于在整个字符串中搜索匹配正则表达式的第一个位置。如果找到匹配的子串，则返回一个匹配对象，否则返回None。import re# 定义正则表达式pattern = r'\d+'# 定义...
search(pattern, text) if match: print("找到匹配的子串:", match.group()) # 输出:找到匹配的子串: 123 else: print("未找到匹配的子串") 在上述代码中,我们首先定义了一个简单的正则表达式r'\d+',用于匹配一个或多个数字。然后,我们定义了目标字符串text,其中包含数字"123"。使用search()方法...
