而casefold()方法是lower()方法的高级版本,它将大写字母转换为小写,包括一些在lower()方法中未指定的特殊字符。ASCII 表例如 'β’这是一个德文字母,它的小写字母是‘ss’。 Syntax of lower():string.lower()参数:It does not take any parameter.返回:It returns a lowercase string of the given string.Sy...
In addition to the upper and lower methods, strings also have a casefold method:>>> word = "Python" >>> word.casefold() 'python' It might seem like casefold does the same thing as lower. And it nearly does.The only difference between casefold and lower is that casefold normalizes a ...
mystring.capitalize( mystring.find( mystring.isdecimal( mystring.istitle( mystring.partition( mystring.rstrip( mystring.translate( mystring.casefold( mystring.format( mystring.isdigit( mystring.isupper( mystring.replace( mystring.split( mystring.upper( mystring.center( mystring.format_map( myst...
.lower(): 这是字符串对象的内置方法,它将字符串中的所有字符转换为小写形式,并返回一个新的字符串。这个方法使用的是默认的小写转换规则,这意味着它可能不适用于所有的语言和字符集。例如,对于某些特殊字符或非英语字符,.lower()方法可能不会正确地进行转换。 .casefold(): 这也是字符串对象的内置方法,它执行一...
lower只支持英文的小写,casefold支持的语种更多(比如德语) 4.字符串upper()函数 ①.功能 将所有字母大写 ②.用法 big_str = string.upper() //括弧不用填写 ③.注意事项 只对字母有效,中文无效。 已经是大写,则无效。 5.字符串swapcase()函数 ①.功能 将字符串中大小写字母进行转化。 ②.用法 newstr = ...
The casefold() method returns a string in all lowercase characters and is similar to lower(). The difference between them is that casefold() is more aggressive in its conversion and can handle certain characters that lower() cannot.my_string = "Hello World" lowercase_string = my_string....
There is yet another difference between string literals and bytes literals. To define bytes literals, you can only use ASCII characters. If you need to insert binary values over the 127 characters, then you have to use the appropriate escape sequence: Python >>> b"Espa\xc3\xb1a" b'Espa...
The casefold() method in Python is used to perform a case-insensitive comparison between two strings. This means it considers upper- and lower-case letters as equivalent, treating them as the same character. Example: str1 = "hello" str2 = "HELLO" if str1.casefold() == str2.casefold()...
