Python Dict：在字典列表中查找键

Question

我有以下列方式看的字典

{
"modules": [
    {
        "outputs": {
            "AdminAZ1": "value1", 
            "AdminAZ2": "value2", 
            "Region": "value3"
       }
    }]
 }

我的问题我需要找到关键＆＃34;输出＆＃34;并返回true

如果确实需要以下列方式输出

"outputs": {
            "AdminAZ1": "value1", 
            "AdminAZ2": "value2", 
            "Region": "value3"
       }

Answer 1

这应该可以帮到你

dict ={
"modules": [
    {
        "outputs": {
            "AdminAZ1": "value1",
            "AdminAZ2": "value2",
            "AWSRegion": "value6"
       }
    }]
 }
#check if outputs is present
print reduce(lambda x,y: x or y, map(lambda x: "outputs" in x.keys(),dict["modules"]), False)
#return outputs if present
print reduce(lambda x,y: x if x else y, map(lambda x: x["outputs"] if "outputs" in x.keys() else None,dict["modules"]), None)

Answer 2

mydict={
"modules": [
{
    "outputs": {
        "AdminAZ1": "value1", 
        "AdminAZ2": "value2", 
        "Region": "value3"
   }
}]}

result = mydict[mydict.keys()[0]][0]
if "outputs" in result:
    print result

结果：

{
    "outputs": {
        "AdminAZ1": "value1", 
        "AdminAZ2": "value2", 
        "Region": "value3"
   }
