使用Python将项目添加到列表

Question

我正在尝试使用.append（）将新项目添加到列表中，但无法解决我的问题，我想将数据插入到列表中，如下所示：

hello = {}

为什么这样？ 我用代码解释了

hello = {} # I don't want to use with hello : []
# Because I'll use it to write into file like this : {u'list1': {'hello1': {}, 'hello2': {}}, u'list2': {'hello3': {}, 'hello4': {}}}

GoodWords = ["hello1", "hello2"]

def Write(filename, data):
    fp = file(filename, 'w')
    fp.write(data)
    fp.close()

"""
Here why I would like to use {} not []
It'll be write like this : {u'list1': {'hello1': {}, 'hello2': {}}}

def start():
    if not "list1" in hello:
        hello["list1"] = {}
    for x in GoodWords:
        hello["list1"][x] = {}
    Write("test.txt", str(hello))


"""

def start():
    # Any idea to use .append() with {} or something like
    for x in GoodWords:
        hello.append(x)

try: start(); sleep(4)
except Exception as why: print why

谢谢。

hello是字典，而不是列表。

无论使用

hello = []

要么

hello[x] = "something"
