        u 'idChecklists': []
}]

最后我想得到所有的名字（testcard1，testcard2，testcard3并打印出来）

我尝试了这段代码（x是上面的列表）

for name in x[0]:
    print name

但如果我跑这个我得

testcard1
testcard2
testcard3

我对python很陌生，我无法理解为什么这不起作用？任何人都可以帮助我吗？

Answer 1

从这个问题来看，可以理解x是一个字典列表。遍历列表x的每个元素，并找到键'name'的值。

for i in x:
     print i['name']

Answer 2

您需要遍历列表，并提取“名称”项：

for item in list:
    print(item['name'])

Answer 3

试试这个，然后打印名称，键：其余项目的值。

for name in x:
    print("\n\n\n\n")
    print name['name']
    print "---------------------------------"
    for data in name:
        print data + " : " + str(name[data])
    print "---------------------------------"

为json表中的每个东西做些什么？
