How to operate slice and list in python and GO Example code
The GO code traverses slices, looks for a certain slice, and counts the number.
type Element interface{} func main() { a := []int{1, 2, 3, 4, 1} for _, i := range a { fmt.Println(i) } for i := 0; i < len(a); i++ { //fmt.Println(i) } fmt.Println(index0(a, 3)) fmt.Println(index0([]string{"a", "b", "c", "d", "e"}, "e")) sort.Ints(a) //排序 fmt.Println(a) } // func index0(a Element, i interface{}) int { if b, ok := a.([]int); ok { if c, ok1 := i.(int); ok1 { for indexC, v := range b { if v == c { return indexC } } } } if b, ok := a.([]string); ok { if c, ok1 := i.(string); ok1 { for indexC, v := range b { if v == c { return indexC } } } } return -1 }
It can be seen that slice in the above GO language does not have a method to find a certain element. I customized a method
The python code below is very concise
a=[1,2,3,4,1] for b in a : print(b) i=0 while i <len(a): print(a[i]) i=i+1 #print( sorted(a)) 方式一排序 a.sort() print(a) print( a.index(3)) a.count(1)
