python - 在python中将分隔字符串转换为分层JSON

Question

如何在 Python 中将定界字符串转换为分层 JSON？ (我看到了一个 solution for a similar question in jQuery 。我一直在尝试为它找到一个 Python 解决方案。)

目标是从一堆 URL 生成类别的分层 JSON，可能如下所示:

sport/tennis/grandslams  
sport/chess  
sport/chess/players/men  
sport/tennis  
sport/cricket/stadiums  
sport/tennis/players  

Answer 1

你可以用字典来实现:

initial = ["Fred-Jim","Fred","Fred-Jim-Bob", "Fred-Jim-Jack", "John", "John-Jim"]

result = {}

for item in initial:
    hierarchy = item.split('-')
    local_result = result
    for node in hierarchy:
        local_result = local_result.setdefault(node, {})

print result

会给你:

{
    'John': {
        'Jim': {}
    }, 
    'Fred': {
        'Jim': {
            'Bob': {},
            'Jack': {}
        }
    }
}
