python - 如何在python中选择嵌套字典中的第一项

Question

我有一个 python 字典，如下所述___

dict = {
  "Moli": {
    "Buy": 75,
    "Sell": 53,
    "Quantity": 300
  }
  "Anna": "Buy": 55,
  "Sell": 83,
  "Quantity": 154
}
"Bob": {
  "Buy": 25,
  "Sell": 33,
  "Quantity": 100
}
"Annie": {
  "Buy": 74,
  "Sell": 83,
  "Quantity": 96
}}

我想i.e: "Moli": {"Buy": 75, "Sell": 53, "Quantity": 300}从python中的这个嵌套字典中选择第一项

如果有人告诉我该怎么做，我将不胜感激:) :) :)

Answer 1

some_dict = {
    "Moli": {
        "Buy": 75,
        "Sell": 53,
        "Quantity": 300},
    "Anna": {
        "Buy": 55,
        "Sell": 83,
        "Quantity": 154},
    "Bob": {
        "Buy": 25,
        "Sell": 33,
        "Quantity": 100},
    "Annie": {
        "Buy": 74,
        "Sell": 83,
        "Quantity": 96}
}
print(some_dict['Moli'])
print(some_dict.keys())
print(some_dict.values())
print(some_dict.items())

希望这会有所帮助！
