Question

我在python中有跟随词：

<scrip>
angular.module('mainApp', ['subModule1', 'subModule2']);

angular.module('subModule1')
   .controller('MyController', ['$scope', function($scope) {
      $scope.moduleName = 'subModule1';
   }]);
</script>
...
<div ng-app="mainApp">
   <div ng-controller="MyController">
   <span ng-bind="moduleName"></span>
</div>

现在我要删除值“DEF”，但将其保留为Key。所以它将是：

d = {'ABC': ["DEF", "ASD"], 'DEF': ["AFS", "UAP"]}

Answer 1

试试这个？

for name, datalist in d.iteritems():  # Or items() in Python 3.x
    for datadict in datalist:
        for key, value in datadict.items():
            if value == "AAA":
                datadict[key] = ""

这有用吗？

Answer 2

d = {'ABC': ["DEF", "ASD"], 'DEF': ["AFS", "UAP"]}
val_to_del = "DEF"

for key in d:

  if val_to_del in d[key]:
    d[key].remove(val_to_del)

print(d)

删除值但保留密钥在python Dict中
