我正在嘗試創建一個具有一些特定值的字典，但它獲得多個相同的值
readers = Readers.objects.all()
count = 0
readersResult = {}
teste = {
"avatar": "",
"firstName": "",
"percent": "",
"lastName": ""
}
for reader in readers:
test["percent"] = "value from another place"
test["firstName"] = reader.firstName
test["lastName"] = reader.lastName
test["avatar"] = reader.avatar
print("TEST: ", test)
readersResult[count] = test
count = count 1
print("RESULT":, readersResult)
我的輸出是：
web_1 | TEST: {'avatar': '/images/avatars/71.png', 'firstName': 'abc', 'percent': '37.08999158957107', 'lastName': 'def'}
web_1 | TEST: {'avatar': '/images/avatars/61.png', 'firstName': 'abc', 'percent': '4.037005887300253', 'lastName': 'def'}
web_1 | RESULT: {0: {'avatar': '/images/avatars/61.png', 'firstName': 'abc', 'percent': '4.037005887300253', 'lastName': 'def'}, 1: {'avatar': '/images/avatars/61.png', 'firstName': 'abc', 'percent': '4.037005887300253', 'lastName': 'def'}}
我究竟做錯了什么 ？

您將相同的字典 ( test) 分配給 中的多個條目readersResult，而不是為每個條目創建一個新的reader。

您可以使用串列作為字典值：
readers = Readers.objects.all()
count = 0
readersResult = {}
teste = {
"avatar": [],
"firstName": [],
"percent": [],
"lastName": []
}
for reader in readers:
test["percent"].append("value from another place")
test["firstName"].append(reader.firstName)
test["lastName"].append(reader.lastName)
test["avatar"].append(reader.avatar)
print("TEST: ", test)
readersResult[count] = test
count = count 1
print("RESULT":, readersResult)

在這里，在您的代碼中，您進行了一個dict命名測驗，然后在每次回圈迭代中將其再次添加到readersResult.
test = {
"avatar": "",
"firstName": "",
"percent": "",
"lastName": ""
}
for reader in readers:
test["percent"] = "value from another place"
test["firstName"] = reader.firstName
test["lastName"] = reader.lastName
test["avatar"] = reader.avatar
print("TEST: ", test)
readersResult[count] = test
count = count 1
您需要在dict每次回圈迭代時創建一個新的。因此，將這部分代碼交換為：
for reader in readers:
test = {}
test["percent"] = "value from another place"
test["firstName"] = reader.firstName
test["lastName"] = reader.lastName
test["avatar"] = reader.avatar
print("TEST: ", test)
readersResult[count] = test
count = count 1
