在 Python 中遍歷嵌套字典

Question

for id, record in people.items():
    for key in record:
        if record["name"].lower() == "agness":
            print(id)
            print(record[key])

執行上面的代碼后，我得到：

yDlgcn99xPc19mYXcRmy
Agness
yDlgcn99xPc19mYXcRmy
25
yDlgcn99xPc19mYXcRmy
Female
94cp4hsyZP2BnCh4D34z
Agness
94cp4hsyZP2BnCh4D34z
25
94cp4hsyZP2BnCh4D34z
Female

我的問題是關於如何在個人信息之前只打印一次id ：

yDlgcn99xPc19mYXcRmy
Agness
25
Female
94cp4hsyZP2BnCh4D34z
Agness
25
Female

Answer 1

嘗試這個 ：

for id, record in people.items():
    first = True
    for key in record:
        if record["name"].lower() == "agness":
            if first: print(id)
            print(record[key])
        first = False
