1)将字符串全体小写。 2.casefold与lower用法 string.casefold(),也就是说:调用字符串的casefold函数,并且函数的()内什么都不用填写,因为它没有参数,不需要传。 casefold会生成一个新的字符串,并且可以把这个新的字符串赋值给一个新的变量,也就是newstr。 lower的用法和casefold是一样的。lower函数的()内也是...
string.casefold官方说明: Casefolding is similar to lowercasing but more aggressive because it is intended to remove all case distinctions in a string. For example, the German lowercase letter'ß'is equivalent to"ss". Since it is already lowercase,lower()would do nothing to'ß';casefold()c...
python 3.3 引入了string.casefold 方法,其效果和 string.lower 非常类似,都可以把字符串变成小写,那么它们之间有什么区别?什么时候该用string.casefold而非string.lower?? In [5]: name = 'Xu Zhoufeng' In [6]: name.casefold() Out[6]: 'xu zhoufeng' In [7]: cname = 'Yu Dongfeng' In [8]: cn...
firstString = "der Fluß" secondString = "der Fluss" # ß is equivalent to ss if firstString.casefold() == secondString.casefold(): print('The strings are equal.') else: print('The strings are not equal.') 在上面的示例中,我应该使用: lower() # the result is not equal which ...
str.casefold()Return a casefolded copy of the string. Casefolded strings may be used for caseless matching.Casefolding is similar to lowercasing but more aggressive because it is intended to remove all case distinctions in a string. For example, the German lowercase letter 'ß...
python is fun In the above example, we have used the casefold() method to convert all the characters of text to lowercase. Here, text.casefold() modifies the value of string1 and returns 'python is fun'. Example 2: casefold() as an Aggressive lower() Method The casefold() method...
以上示例中,最后的输出结果都是'i love python'。 那么这两个函数有什么区别呢? 首先想到的是,查看帮助,使用help方法: >>>help(str.lower) Help on method_descriptor: lower(...) S.lower()->str Return a copy of the string S converted to lowercase.>>>help(str.casefold) ...
例子1 :# Create example character string x <- "GeeksforGeeks" # Convert to lower case letters x <- casefold(x, upper = FALSE) print(x) R Copy输出"geeksforgeeks" R Copy在上面的代码中,大写的布尔值被设置为FALSE,以将字符向量转换为小写。
Python String casefold()用法及代码示例 casefold() 方法是一种激进的lower() 方法,它将字符串转换为大小写折叠字符串以进行无大小写匹配。 casefold()方法删除string中存在的所有大小写区别。它用于无大小写匹配,即在比较时忽略大小写。 例如,德语小写字母ß等价于ss。但是,由于ß已经是小写字母,因此lower()...
