你可以通过PyYAML尝试YAML。它的输出可以微调。我建议从以下开始:

print(yaml.dump(data, allow_unicode=True, default_flow_style=False))

结果非常易读;如果需要，还可以解析回Python。

编辑:

例子:

>>> import yaml
>>> data = {'a':2, 'b':{'x':3, 'y':{'t1': 4, 't2':5}}}
>>> print(yaml.dump(data, default_flow_style=False))
a: 2
b:
  x: 3
  y:
    t1: 4
    t2: 5

这里有一些东西可以打印任何类型的嵌套字典，同时跟踪“父”字典。

dicList = list()

def prettierPrint(dic, dicList):
count = 0
for key, value in dic.iteritems():
    count+=1
    if str(value) == 'OrderedDict()':
        value = None
    if not isinstance(value, dict):
        print str(key) + ": " + str(value)
        print str(key) + ' was found in the following path:',
        print dicList
        print '\n'
    elif isinstance(value, dict):
        dicList.append(key)
        prettierPrint(value, dicList)
    if dicList:
         if count == len(dic):
             dicList.pop()
             count = 0

prettierPrint(dicExample, dicList)

这是根据不同格式进行打印的一个很好的起点，就像op中指定的那样。你真正需要做的只是围绕打印块进行操作。注意，它将查看该值是否为'OrderedDict()'。这取决于你是否使用容器数据类型集合中的东西，你应该做这些故障保护，这样elif块不会因为它的名字而把它视为一个额外的字典。就像现在，一个例子字典

example_dict = {'key1': 'value1',
            'key2': 'value2',
            'key3': {'key3a': 'value3a'},
            'key4': {'key4a': {'key4aa': 'value4aa',
                               'key4ab': 'value4ab',
                               'key4ac': 'value4ac'},
                     'key4b': 'value4b'}

将打印

key3a: value3a
key3a was found in the following path: ['key3']

key2: value2
key2 was found in the following path: []

key1: value1
key1 was found in the following path: []

key4ab: value4ab
key4ab was found in the following path: ['key4', 'key4a']

key4ac: value4ac
key4ac was found in the following path: ['key4', 'key4a']

key4aa: value4aa
key4aa was found in the following path: ['key4', 'key4a']

key4b: value4b
key4b was found in the following path: ['key4']

~修改代码以适应问题的格式~

lastDict = list()
dicList = list()
def prettierPrint(dic, dicList):
    global lastDict
    count = 0
    for key, value in dic.iteritems():
        count+=1
        if str(value) == 'OrderedDict()':
            value = None
        if not isinstance(value, dict):
            if lastDict == dicList:
                sameParents = True
            else:
                sameParents = False

            if dicList and sameParents is not True:
                spacing = ' ' * len(str(dicList))
                print dicList
                print spacing,
                print str(value)

            if dicList and sameParents is True:
                print spacing,
                print str(value)
            lastDict = list(dicList)

        elif isinstance(value, dict):
            dicList.append(key)
            prettierPrint(value, dicList)

        if dicList:
             if count == len(dic):
                 dicList.pop()
                 count = 0

使用相同的示例代码，它将打印以下内容:

['key3']
         value3a
['key4', 'key4a']
                  value4ab
                  value4ac
                  value4aa
['key4']
         value4b

This isn't exactly what is requested in OP. The difference is that a parent^n is still printed, instead of being absent and replaced with white-space. To get to OP's format, you'll need to do something like the following: iteratively compare dicList with the lastDict. You can do this by making a new dictionary and copying dicList's content to it, checking if i in the copied dictionary is the same as i in lastDict, and -- if it is -- writing whitespace to that i position using the string multiplier function.

使用这个函数:

def pretty_dict(d, n=1):
    for k in d:
        print(" "*n + k)
        try:
            pretty_dict(d[k], n=n+4)
        except TypeError:
            continue

这样叫它:

pretty_dict(mydict)

我尝试了以下方法，得到了我想要的结果

方法1: 步骤1:在cmd中输入以下命令安装print_dict

pip install print_dict

步骤2:导入print_dict as

from print_dict import pd

步骤3:使用pd打印

pd(your_dictionary_name)

示例输出:

{
    'Name': 'Arham Rumi',
    'Age': 21,
    'Movies': ['adas', 'adfas', 'fgfg', 'gfgf', 'vbxbv'],
    'Songs': ['sdfsd', 'dfdgfddf', 'dsdfd', 'sddfsd', 'sdfdsdf']
}

方法2: 我们也可以使用for循环来使用items方法打印字典

for key, Value in your_dictionary_name.items():
    print(f"{key} : {Value}")

yapf的另一个选择:

from pprint import pformat
from yapf.yapflib.yapf_api import FormatCode

dict_example = {'1': '1', '2': '2', '3': [1, 2, 3, 4, 5], '4': {'1': '1', '2': '2', '3': [1, 2, 3, 4, 5]}}
dict_string = pformat(dict_example)
formatted_code, _ = FormatCode(dict_string)

print(formatted_code)

输出:

{
    '1': '1',
    '2': '2',
    '3': [1, 2, 3, 4, 5],
    '4': {
        '1': '1',
        '2': '2',
        '3': [1, 2, 3, 4, 5]
    }
}

通过这种方式，你可以打印在漂亮的方式，例如你的字典名字是yasin

import json

print (json.dumps(yasin, indent=2))

或者,更安全:

print (json.dumps(yasin, indent=2, default=str))
