字符串库提供了 string.lower() 方法,可以将字符串转换为小写。我们可以使用这个方法将字符串转换为小写,然后用 replace() 方法替换字符串。 def case_insensitive_replace(string, old, new): """ Performs a case-insensitive replacement on a string. Args: string: The string to search in. old: The...
例如: defstarts_with_A_case_insensitive(string):returnstring.lower().startswith('a')# 测试print(starts_with_A_case_insensitive("Apple"))# 输出: Trueprint(starts_with_A_case_insensitive("apple"))# 输出: Trueprint(starts_with_A_case_insensitive("Banana"))# 输出: False 1. 2. 3. 4. ...
find()函数会返回子串在字符串中的起始位置,如果找不到则返回-1。 4. 完整代码示例 下面是完整的代码示例: deffind_case_insensitive(string,substring):string_lower=string.lower()substring_lower=substring.lower()index=string_lower.find(substring_lower)returnindex# 调用示例string="Hello World"substring="WO...

#Case-insensitive string comparison in Python In our above examples, we use the case of letters for string comparison. However, if you want the string comparison to be case-insensitive, use the lower() method with the strings you are comparing. Here is an example. ...
Strings in Python are case-sensitive, which means thatMoonandmoonare considered different words. To do a case-insensitive comparison, you can convert a string to all lowercase letters by using the.lower()method: Python print("The Moon And The Earth".lower()) ...
这样就完成了将'CaseInsensitiveDict'转换为JSON的过程。 CaseInsensitiveDict是一个不区分大小写的字典对象,它可以用于存储HTTP请求头部信息或其他需要不区分大小写的键值对。将CaseInsensitiveDict转换为JSON可以方便地进行数据传输和存储。 推荐的腾讯云相关产品:腾讯云对象存储(COS)腾讯云对象存储(COS)是一种海量、安全、...
