Rust中特别的“区间”概念

  • 1、半开区间，用下面的运算符表示 
..
Enter fullscreen mode Exit fullscreen mode
  • 2、闭区间，用下面的运算符表示 
..=
Enter fullscreen mode Exit fullscreen mode
  • 3、举个迭代区间元素的列子 
// Rust
fn main() {
for i in 1..=5 {
    println!("{}",i);
}
}
Enter fullscreen mode Exit fullscreen mode 
# Python
for i in range(1,6):
    print(i)
Enter fullscreen mode Exit fullscreen mode
  • 4、含义：半开区间只包括区间起始值，不包括结束值；闭区间包括起始值和结束值
  • 5、Python中并不存在这样的运算符来区分闭区间和半开区间，Python中只有半开的概念（不包括结束值）
  • 6、学Rust后才明白对某个区间还能这么分，甚至写了好几年的Python都没听过“区间”这个词汇
