Python plistlib：没有正确嵌套？
我的代码：
current_bex = dict(
objectName = 'myData',
objects = list(
dict(
one = 1,
foo = 'bar',
),
), )
try:
writePlist(current_bex, 'someFile.plist') except TypeError:
print 'caught typeerror'
结果：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>objectName</key>
<string>myData</string>
<key>objects</key>
<array>
<string>foo</string>
<string>one</string>
</array>
</dict>
</plist>
我的问题是，为什么在嵌套数组中，我有简单的字符串，而不是
编辑：
current_bex = dict(
objectName = 'myData',
objects = [
{
'one': 1,
'foo': 'bar',
},
{
'something': 'goes here',
},
],
)
工作正常。显然我对 dict() 和 list() 的使用不正确？谁能阐明这一点？
My code:
current_bex = dict(
objectName = 'myData',
objects = list(
dict(
one = 1,
foo = 'bar',
),
), )
try:
writePlist(current_bex, 'someFile.plist') except TypeError:
print 'caught typeerror'
results in:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>objectName</key>
<string>myData</string>
<key>objects</key>
<array>
<string>foo</string>
<string>one</string>
</array>
</dict>
</plist>
My question is, why, in the nested array, do I have simple strings, rather than <key>foo</key><string>bar</string>, etc?
EDIT:
current_bex = dict(
objectName = 'myData',
objects = [
{
'one': 1,
'foo': 'bar',
},
{
'something': 'goes here',
},
],
)
works fine. Apparently my use of dict() and list() is incorrect? Can anyone shed light on this?

这里有两件事：
list()构造函数不将单个内容项作为参数，它采用可迭代的项。因此，您可以编写列表文字语法[1, 2, 3]，但不能编写list(1, 2, 3)。字典是可迭代的，并生成其键作为其值。
因此，如果您从字典构造一个列表，结果将是该字典的键列表，而不是包含字典的列表。这正是您在结果列表中看到的内容。
Two things here:
The
list()constructor doesn't take individual content items as arguments, it takes an iterable of items. So you can write the list literal syntax[1, 2, 3], but notlist(1, 2, 3).A dict is iterable, and yields its keys as its values.
So, if you construct a list from a dict, the result will be a list of the keys of the dict, not a list containing a dict. That's exactly what you're seeing in the resulting plist.
