lower(), new) return new_string if __name__ == "__main__": string = "Hello World" old = "World" new = "Python" new_string = case_insensitive_replace(string, old, new) print(new_string) 方法四:使用第三方库 有一些第三方库提供了对大小写不敏感的字符串操作函数。例如,FuzzyWuzzy 库...
str4 = "python" if str3.lower() == str4.lower(): print("Strings are equal (case-insensitive)") else: print("Strings are not equal (case-insensitive)") 逻辑运算符 在if语句的条件部分,我们可以使用逻辑运算符(and,or,not)来组合多个条件: name = "Alice" age = 25 if name == "Alice"...
In the following example, we use there.search()function to search for the string “python” within the text “Learning Python is fun!”. There.IGNORECASEflag is used to make the search case-insensitive, ensuring that the function matches “python”, “Python”, “PYTHON”, or any other var...

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...
In this scenario, we have auser_inputstring representing a user’s input, and we want to check if it contains thekeyword“apple” regardless of the case. By converting both theuser_inputandkeywordto lowercase using thelower()method, we can perform a case-insensitive check using theinoperator...

You can use it in two ways. The first is to use the contains method of the String object you are checking: my_string = ‘This is the string being checked.” my_substring = ‘string’ if (my_string.__contains__(my_substring)): ...

In this unit, you use the most common string methods in Python to manipulate strings, from simple transformations to more advanced search-and-replace operations.
