3.re.I 或者 re.IGNORECASE 功能:Perform case-insensitive matching; expressions like[A-Z]will also match lowercase letters. Full Unicode matching (such asÜmatching ü) also works unless there.ASCIIflag is used to disable non-ASCII matches. The current locale does not change the effect of this...

上面的代码将输出"匹配成功",因为在模式匹配时,re.IGNORECASE标志会忽略大小写。 4. 自定义函数 如果上述方法无法满足我们的需求,我们还可以自定义一个函数来实现忽略大小写的功能。下面是一个简单的示例: defcase_insensitive_equal(str1,str2):returnstr1.lower()==str2.lower()result=case_insensitive_equal(...
Python3将'CaseInsensitiveDict'转换为JSON的过程如下: 首先,需要导入相应的库: 代码语言:txt 复制 import json from requests.structures import CaseInsensitiveDict 然后,创建一个CaseInsensitiveDict对象: 代码语言:txt 复制 headers = CaseInsensitiveDict() headers["Content-Type"] = "application/json" headers["...
