垂直打印列表字典

Question

我想垂直打印以下列表字典：

result = {'WeightedLevel': [388.850952, 716.718689, 1312.55957, 2405.087158, 4460.083984, 8543.792969, 18805.201172, 57438.140625, 1792.367554], 'Job': 'Desktop', 'LoadLevel': [0.212399, 0.393191, 0.727874, 1.347436, 2.494368, 4.617561, 8.548006, 15.824027, 1.0], 'Task': 'test', 'Failure': [2.0, 2.0, 2.0, 2.0, 2.0, 2.0, 2.0, 2.0, 2.0], 'Blocks': [7255.151855, 231.589661, 9.365415, 0.55364, 0.0504, 0.006408, 0.001204, 0.000842, 2.060041]}

所以它应该是这样的：

Job           Task          LoadLevel         Blocks          Failure         WeightedLevel
Desktop       test          4546543           4384284         0,46544564      0,1354385
                            474454            978456          2               9655
                            9655              55654           966             665 

等等……

我尝试了一些我在网上找到的代码，但它们仍然水平打印结果：

for k, d in result.items():
    print(k + ":", d)         

和

print("\t".join(str(x) for x in result))

漂亮的打印表格需要大量代码（table-recipe、pretty-table）。临时编写这种代码并不好玩；您不妨使用设计良好的模块。

如果你有pandas，你可以将dict直接转储到DataFrame中，然后像这样打印：

In [4]: import pandas as pd
In [5]: result = {'WeightedLevel': [388.850952, 716.718689, 1312.55957, 2405.087158, 4460.083984, 8543.792969, 18805.201172, 57438.140625, 1792.367554], 'Job': 'Desktop', 'LoadLevel': [0.212399, 0.393191, 0.727874, 1.347436, 2.494368, 4.617561, 8.548006, 15.824027, 1.0], 'Task': 'test', 'Failure': [2.0, 2.0, 2.0, 2.0, 2.0, 2.0, 2.0, 2.0, 2.0], 'Blocks': [7255.151855, 231.589661, 9.365415, 0.55364, 0.0504, 0.006408, 0.001204, 0.000842, 2.060041]}

In [6]: pd.DataFrame(result)
Out[6]: 
        Blocks  Failure      Job  LoadLevel  Task  WeightedLevel
0  7255.151855        2  Desktop   0.212399  test     388.850952
1   231.589661        2  Desktop   0.393191  test     716.718689
2     9.365415        2  Desktop   0.727874  test    1312.559570
3     0.553640        2  Desktop   1.347436  test    2405.087158
4     0.050400        2  Desktop   2.494368  test    4460.083984
5     0.006408        2  Desktop   4.617561  test    8543.792969
6     0.001204        2  Desktop   8.548006  test   18805.201172
7     0.000842        2  Desktop  15.824027  test   57438.140625
8     2.060041        2  Desktop   1.000000  test    1792.367554

[9 rows x 6 columns]

这是一种无需使用第三方模块即可以表格格式打印 dict 的方法：

import itertools as IT

result = {'WeightedLevel': [388.850952, 716.718689, 1312.55957, 2405.087158, 4460.083984, 8543.792969, 18805.201172, 57438.140625, 1792.367554], 'Job': 'Desktop', 'LoadLevel': [0.212399, 0.393191, 0.727874, 1.347436, 2.494368, 4.617561, 8.548006, 15.824027, 1.0], 'Task': 'test', 'Failure': [2.0, 2.0, 2.0, 2.0, 2.0, 2.0, 2.0, 2.0, 2.0], 'Blocks': [7255.151855, 231.589661, 9.365415, 0.55364, 0.0504, 0.006408, 0.001204, 0.000842, 2.060041]}

matrix = zip(*[value if isinstance(value, list) else IT.repeat(value) for key,value in result.items()])
print(''.join(['{:15}'.format(key) for key in result.keys()]))
for row in matrix:
    print(''.join(['{:15}'.format(str(item)) for item in row]))

Answer 2

如果它们的长度都相同，这将很容易。您要做的是拆分字典，然后在 print 语句中使用 end kwarg 循环打印。

如下所示。如果你把每个项目都做成一个长度相同的列表，那就更容易了。

def print_dict_table(result):
    """Print a dictionary of lists like a table.

    Args:
        result (dict): Dictionary of lists to print as a table.
    """
    # Count the longest value
    keys = result.keys()
    count = 0
    for i in result.values():
        if isinstance(i, list) and len(i) > count:
            count = len(i)

    # print header
    for i in keys:
        print(i, end="\t")
    print()

    # print columns
    for i in range(count):
        for j in keys:
            if isinstance(result[j], list) and len(result[j]) >= i:
                    print(result[j][i], end="\t")
            else:
                print(result[j], end="\t")
        print()
# end print_dict_table


result = {'WeightedLevel': [388.850952, 716.718689, 1312.55957, 2405.087158, 4460.083984, 8543.792969, 18805.201172, 57438.140625, 1792.367554], 'Job': 'Desktop', 'LoadLevel': [0.212399, 0.393191, 0.727874, 1.347436, 2.494368, 4.617561, 8.548006, 15.824027, 1.0], 'Task': 'test', 'Failure': [2.0, 2.0, 2.0, 2.0, 2.0, 2.0, 2.0, 2.0, 2.0], 'Blocks': [7255.151855, 231.589661, 9.365415, 0.55364, 0.0504, 0.006408, 0.001204, 0.000842, 2.060041]}

print_dict_table(result)

结果

字典没有排序。老实说，我会重新定义您的数据结构。如果是表格数据，则使用表格。
