In that case, you can cut (CTRL + x) the existing map, select the correct target field, and then select paste (CTRL + V).
对于这种情况，可以剪切(CTRL +X)现有映射，选择正确的目标字段然后选择粘帖(CTRL +V)。
Like filter , map evaluates the string passed as its second argument, passing each list element in turn, via v: val.
和filter一样，map计算作为第二个参数传递的字符串，并且通过v：val传递每个列表元素。
The call to map walks through each value, aliases it to v: val, evaluates the expression in the string, and replaces the value with the result of that expression.
调用map可以遍历各个值，将其作为别名赋给v：val，在字符串中计算表达式，并用表达式结果替换值。
We are trying to locate the shop on the map. (v. discover the exact position of sth. )
我们试图在地图上找到商店的位置。
