不变性意味如果两个字符串共享相同的底层数据的话也是安全的，这使得复制任何长度的字符串代价是低廉的。同样，一个字符串s和对应的子字符串切片s[7:]的操作也可以安全地共享相同的内存，因此字符串切片操作代价也是低廉的。在这两种情况下都没有必要分配新的内存。 图3.4演示了一个字符串和两个字串共享相同的底层数据。 不变性意味如果两个字符串共享相同的底层数据的话也是安全的，这使得复制任何长度的字符串代价是低廉的。同样，一个字符串s和对应的子字符串切片s[7:]的操作也可以安全地共享相同的内存，因此字符串切片操作代价也是低廉的。在这两种情况下都没有必要分配新的内存。 图3.4演示了一个字符串和两个子串共享相同的底层数据。
