如何漂亮地打印嵌套词典? [英] How to pretty print nested dictionaries?

问题描述

如何在Python中打印深度约为4的字典?我尝试使用pprint()进行漂亮的打印，但是没有用:

How can I pretty print a dictionary with depth of ~4 in Python? I tried pretty printing with pprint(), but it did not work:

import pprint 
pp = pprint.PrettyPrinter(indent=4)
pp.pprint(mydict)

我只是想为每个嵌套添加一个缩进("\t")，这样我就得到了这样的东西:

I simply want an indentation ("\t") for each nesting, so that I get something like this:

key1
    value1
    value2
    key2
       value1
       value2

等

我该怎么做?

推荐答案

我不确定您希望格式看起来如何，但是可以从这样的函数开始:

I'm not sure how exactly you want the formatting to look like, but you could start with a function like this:

def pretty(d, indent=0):
   for key, value in d.items():
      print('\t' * indent + str(key))
      if isinstance(value, dict):
         pretty(value, indent+1)
      else:
         print('\t' * (indent+1) + str(value))
