解析任意json树的python、递归和函数方法:
handlers = {
list: iterate,
dict: delve,
str: emit_li,
float: emit_li,
}
def emit_li(stuff, strong=False):
emission = '<li><strong>%s</strong></li>' if strong else '<li>%s</li>'
print(emission % stuff)
def iterate(a_list):
print('<ul>')
map(unravel, a_list)
print('</ul>')
def delve(a_dict):
print('<ul>')
for key, value in a_dict.items():
emit_li(key, strong=True)
unravel(value)
print('</ul>')
def unravel(structure):
h = handlers[type(structure)]
return h(structure)
unravel(data)

数据
是一个python列表(从json文本字符串解析):
data = [
{'data': {'customKey1': 'customValue1',
'customKey2': {'customSubKey1': {'customSubSubKey1': 'keyvalue'}}},
'geometry': {'location': {'lat': 37.3860517, 'lng': -122.0838511},
'viewport': {'northeast': {'lat': 37.4508789,
'lng': -122.0446721},
'southwest': {'lat': 37.3567599,
'lng': -122.1178619}}},
'name': 'Mountain View',
'scope': 'GOOGLE',
'types': ['locality', 'political']}
