字符串类型转换函数,这几个函数只在string模块中有 string.atoi(s[,base]) #base默认为10,如果为0,那么s就可以是012或0x23这种形式的字符串,如果是16那么s就只能是0x23或0X12这种形式的字符串 string.atol(s[,base]) #转成long string.atof(s[,base]) #转成float 1. 2. 3. 4. 这里再次强调,字符...
split()可以基于指定分隔符将字符串分隔成多个子字符串(存储到列表中)。如果不指定分隔 符,则默认使用空白字符(换行符/空格/制表符)。示例代码如下: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 >>>a="to be or not to be">>>a.split()['to','be','or','not','to','be']>>>a.split(...

python选择的是第一种解决办法。类似的还有str(arg)函数,它把arg用string类型表示出来。 字符串中字符大小写的变换: S.lower() #小写 S.upper() #大写 S.swapcase() #大小写互换 S.capitalize() #首字母大写 String.capwords(S) #这是模块中的方法。它把S用split()函数分开,然后用capitalize()把首字母...
