new_string = case_insensitive_replace(string, "hello", "Hi") print(new_string) # 输出:Hi World 在上述示例中,case_insensitive_replace()函数接受三个参数:原始字符串string、要替换的旧字符串old和替换的新字符串new。函数内部使用re.escape()函数来转义旧字符串中的特殊字符,并使用re.IGNORECASE标志来忽...

re 模块 在 Python 中，正则表达式功能由 re 模块提供。此模块支持模式匹配、搜索和字符串操作。re.search()、re.match() 和 re.sub() 等内置函数允许进行复杂的模式匹配。如果没有 re 模块，Python 支持使用 .find()、.startswith()、.endswith() 和 .replace() 等方法进行基本模式匹配。虽然这些内置方法...
First, we need to create a function to replace uppercase letters with a lowercase letter Next, we need to pass this function as the replacement argument to there.sub() Wheneverre.sub()matches the pattern, It will send the corresponding match object to the replacement function ...

replace用于将指定模式替换为另一个模式。通过传入空字符串,它也常常用于删除模式: In [146]: val.replace(',', '::') Out[146]: 'a::b:: guido' In [147]: val.replace(',', '') Out[147]: 'ab guido' 表7-3列出了Python内置的字符串方法。
