你可以使用打印字典

from print_dict import pd

dict1 = {
    'key': 'value'
} 

pd(dict1)

输出:

{
    'key': 'value'
}

此Python代码的输出:

{
    'one': 'value-one',
    'two': 'value-two',
    'three': 'value-three',
    'four': {
        '1': '1',
        '2': '2',
        '3': [1, 2, 3, 4, 5],
        '4': {
            'method': <function custom_method at 0x7ff6ecd03e18>,
            'tuple': (1, 2),
            'unicode': '✓',
            'ten': 'value-ten',
            'eleven': 'value-eleven',
            '3': [1, 2, 3, 4]
        }
    },
    'object1': <__main__.Object1 object at 0x7ff6ecc588d0>,
    'object2': <Object2 info>,
    'class': <class '__main__.Object1'>
}

安装:

$ pip install print-dict

披露:我是print-dict的作者

下面是我根据sth的注释写的函数。它的工作原理与json相同。转储与缩进，但我使用制表符而不是缩进的空间。在Python 3.2+中，您可以直接将缩进指定为'\t'，但在2.7中不能。

def pretty_dict(d):
    def pretty(d, indent):
        for i, (key, value) in enumerate(d.iteritems()):
            if isinstance(value, dict):
                print '{0}"{1}": {{'.format( '\t' * indent, str(key))
                pretty(value, indent+1)
                if i == len(d)-1:
                    print '{0}}}'.format( '\t' * indent)
                else:
                    print '{0}}},'.format( '\t' * indent)
            else:
                if i == len(d)-1:
                    print '{0}"{1}": "{2}"'.format( '\t' * indent, str(key), value)
                else:
                    print '{0}"{1}": "{2}",'.format( '\t' * indent, str(key), value)
    print '{'
    pretty(d,indent=1)
    print '}'

Ex:

>>> dict_var = {'a':2, 'b':{'x':3, 'y':{'t1': 4, 't2':5}}}
>>> pretty_dict(dict_var)
{
    "a": "2",
    "b": {
        "y": {
            "t2": "5",
            "t1": "4"
        },
        "x": "3"
    }
}

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}")

从这个链接:

def prnDict(aDict, br='\n', html=0,
            keyAlign='l',   sortKey=0,
            keyPrefix='',   keySuffix='',
            valuePrefix='', valueSuffix='',
            leftMargin=0,   indent=1 ):
    '''
return a string representive of aDict in the following format:
    {
     key1: value1,
     key2: value2,
     ...
     }

Spaces will be added to the keys to make them have same width.

sortKey: set to 1 if want keys sorted;
keyAlign: either 'l' or 'r', for left, right align, respectively.
keyPrefix, keySuffix, valuePrefix, valueSuffix: The prefix and
   suffix to wrap the keys or values. Good for formatting them
   for html document(for example, keyPrefix='<b>', keySuffix='</b>'). 
   Note: The keys will be padded with spaces to have them
         equally-wide. The pre- and suffix will be added OUTSIDE
         the entire width.
html: if set to 1, all spaces will be replaced with '&nbsp;', and
      the entire output will be wrapped with '<code>' and '</code>'.
br: determine the carriage return. If html, it is suggested to set
    br to '<br>'. If you want the html source code eazy to read,
    set br to '<br>\n'

我必须传递默认参数，就像这样:

print(json.dumps(my_dictionary, indent=4, default=str))

如果你想要键排序，你可以这样做:

print(json.dumps(my_dictionary, sort_keys=True, indent=4, default=str))

为了修复此类型错误:

TypeError: Object of type 'datetime' is not JSON serializable

这是由于datetimes是字典中的一些值。

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))
