python中向列表中添加字典時,都是重複數據，後面一條覆蓋前面一條數據

result = {} # 錯誤位置
data = []  # 最終取到的數據
for a in list(case_fail):
    a = list(a)
    print("失敗的數據")
    print(a)

    result["id"] = a[0]
    result["Product_id"] = a[1]
    result["Webcasemodel_id"] = a[2]
    result["webcasename"] = a[3]
    result["webtestresult"] = a[4]
    result["webtester"] = a[5]
    result["create_time"] = a[6]
    result["detail"] = "detail"
    result["delete"] = "delete"
    result["error"] = a[7]
    data.append(result)
    print("失敗的數據result")
    print(result)

data = []  # 最終取到的數據
for a in list(case_fail):
    a = list(a)
    print("失敗的數據")
    print(a)
    result = {}  # 一定要把字典聲明成局部變量，否則字典放進列表裏，會不斷的最後一條新數據覆蓋上一條數據
    result["id"] = a[0]
    result["Product_id"] = a[1]
    result["Webcasemodel_id"] = a[2]
    result["webcasename"] = a[3]
    result["webtestresult"] = a[4]
    result["webtester"] = a[5]
    result["create_time"] = a[6]
    result["detail"] = "detail"
    result["delete"] = "delete"
    result["error"] = a[7]
    data.append(result)
    print("失敗的數據result")
    print(result)
