Library Reference Manual .) List. index (x) Returns the index of the first x element in the linked list. If no matching element exists, an error is returned. List. count (x) Returns the number of times x appears in the linked list. List. sort () Sort the elements in the linked list in the local area. List. reverse () In-Place inverted list elements. Example:Copy codeThe Code is as follows:>>> A = [66.25, 333,333, 1, 1234.5]>>> Print a. count (333), a

1,foreach is the cyclic output of an array of PHP. Example: $arr = Array ("1" = "111", "2" = "222", "3" = "333"), and foreach ($arr as $key = = $value) { echo $key. = ". $value." \ n ";} The results are as follows: 1=>1112=>2223=>333 2, make a slight change: foreach ($arr as $key = + $value) {//echo $key. " = ". $value." \ n "; $key = $arr [$key];} Print_r ($arr); The results are as follows: Array ( [
