In the following example, we are going to use list comprehension along with the join(). Open Compiler x = "tp, tutorialspoint" y = ''.join([char.upper() if char.islower() else char for char in x]) print("Result :", y) Output Following is the output of the above program ? Re...
let s = s.to_str().unwrap().to_uppercase(); // 将 String 转成 *mut char 返回 CString::new(s).unwrap().into_raw()} 解释一下里面的 CStr 和 CString,在 Rust 中,CString 用于创建 C 风格的字符串(以 \0 结尾),拥有自己的内存。关键的是,CString 拥有值的所有权,当实例离开作用域时,它...

str.rjust(width[, fillchar])返回长度为 width 的字符串,原字符串在其中靠右对齐。 使用指定的 fillchar 填充空位 (默认使用 ASCII 空格符)。 如果 width 小于等于 len(s) 则返回原字符串的副本。 str.rpartition(sep)在 sep 最后一次出现的位置拆分字符串,返回一个 3 元组,其中包含分隔符之前的部分、分隔...
