go map总结

1.map声明初始化
var m map[int]string
m = map[int]string{}
m = make(map[int]string)k
声明并初始化
m := map[int]string{}
m:= make(map[int]string)
2.map增删改查
m[1] = “paris”
delete (m,paris)
i :=m[1]
i, ok := m[1]
_, ok := m[1]
map随机遍历
for k, v := range m {
fmt.Println(m(k))
}
range是无序的所以现在我们需要对map进行有序遍历
import “sort”
keys []string
for k, v := range m {
keys = append(keys, k)
sort(keys)
for _, k := range keys{
fmt.Println(k)
}
}
