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}")

最简单的方法是安装IPython并使用如下所示的方法

from IPython.lib.pretty import pretty


class MyClass:
    __repr__(self):
       return pretty(data)  # replace data with what makes sense

在你的情况下

print(pretty(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}")

我把sth的答案稍微修改一下，以适应我的嵌套字典和列表的需要:

def pretty(d, indent=0):
    if isinstance(d, dict):
        for key, value in d.iteritems():
            print '\t' * indent + str(key)
            if isinstance(value, dict) or isinstance(value, list):
                pretty(value, indent+1)
            else:
                print '\t' * (indent+1) + str(value)
    elif isinstance(d, list):
        for item in d:
            if isinstance(item, dict) or isinstance(item, list):
                pretty(item, indent+1)
            else:
                print '\t' * (indent+1) + str(item)
    else:
        pass

然后输出如下:

>>> 
xs:schema
    @xmlns:xs
        http://www.w3.org/2001/XMLSchema
    xs:redefine
        @schemaLocation
            base.xsd
        xs:complexType
            @name
                Extension
            xs:complexContent
                xs:restriction
                    @base
                        Extension
                    xs:sequence
                        xs:element
                            @name
                                Policy
                            @minOccurs
                                1
                            xs:complexType
                                xs:sequence
                                    xs:element
                                            ...

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.

晚了，但是这个答案不需要任何额外的库。类似于STH的答案，但在格式上更健壮一点，并返回一个完整的字符串，然后可以打印:

def pretty_print_dict(
        input_dictionary,
        indent=1,
        depth=0
):
    # Bool flag to add comma's after first item in dict.
    needs_comma = False
    # String for any dict will start with a '{'
    return_string = '\t' * depth + '{\n'
    # Iterate over keys and values, building the full string out.
    for key, value in input_dictionary.items():
        # Start with key. If key follows a previous item, add comma.
        if needs_comma:
            return_string = return_string + ',\n' + '\t' * (depth + 1) + str(key) + ': '
        else:
            return_string = return_string + '\t' * (depth + 1) + str(key) + ': '
        # If the value is a dict, recursively call function.
        if isinstance(value, dict):
            return_string = return_string + '\n' + pretty_print_dict(value, depth=depth+2)
        else:
            return_string = return_string + '\t' * indent + str(value)
        # After first line, flip bool to True to make sure commas make it.
        needs_comma = True
    # Complete the dict with a '}'
    return_string = return_string + '\n' + '\t' * depth + '}'
    # Return dict string.
    return return_string

让我们看看它如何处理像test_dict={1,2,3:{4:{5:6}， 7:8}， 9:10}这样的字典。

字符串的样子:“{\ n \ t1: \ t2, t3: \ n \ \ n \ t \ {\ n \ t \ \ t4: \ n \ t \ t \ \ {\ n \ t \ t \ \ \ t5: \ t6 \ n \ t \ t \ \ t}, \ n \ t \ \ t7: \ t8 \ n \ t \ t}, \ n \ t9: \ t10 \ n}”。

打印该字符串会得到:

{
    1:  2,
    3: 
        {
            4: 
                {
                    5:  6
                },
            7:  8
        },
    9:  10
}
