从 python 字典中打印列

Question

我有一个超过一周的提交字典。我想以每周日历样式的列打印出来。

{
  'Fri': 
  ['Commit: 04:15PM Move flex to mixin and do mobile-first queries\n', 
   'Commit: 03:52PM use padding to get the margins\n', 
   'Commit: 10:09AM Remove field_prepared_logo height\n', 
   'Commit: 03:15PM Add the final div to footer\n', 
   'Commit: 03:05PM Merge from redesign\n'], 
  'Thu': 
  ['Commit: 10:25AM Design qa fixes on /clients page\n'], 
  'Tue': ['Commit: 09:40AM remove transform and tweak span placement in hamburger\n'], 
  'Wed': ['Commit: 02:19PM Change blockquote font and width\n']}

似乎使用numpy 是在列中打印出来的方法。我还能够通过添加一些虚拟字符串并将字典转换为数组数组来“平衡”列表。我正在努力解决的问题是如何将数组数组转换为正确的numpy 数组。

“均衡”的数组数组：

[ 
['Commit: 09:40AM remove transform and tweak span placement in hamburger\n', 'X', 'X', 'X', 'X']
['Commit: 02:19PM Change blockquote font and width\n', 'X', 'X', 'X', 'X']
['Commit: 04:15PM Move flex to mixin and do mobile-first queries\n', 'Commit: 03:52PM use padding to get the margins\n', 'Commit: 10:09AM Remove field_prepared_logo height\n', 'Commit: 03:15PM Add the final yeti to footer\n', 'Commit: 03:05PM Merge from p-redesign\n']
['Commit: 10:25AM Design qa fixes on /clients page\n', 'X', 'X', 'X', 'X']
]

我尝试过的：

nump_array = numpy.array(array_of_arrays)
print(nump_array[:,0])

这总是错误IndexError: too many indices for array。我认为我需要做的是进入并将这些内部数组转换为 numpy 数组，然后 vstack 他们，但我很不清楚如何处理 numpy。我也想知道我是否不应该从一开始就这么快把字典扔掉。

这是我正在寻找的缩短版：

|  Mon  |  Tue  |  Wed  |  Thu  |  Fri  |
| 04:15 | 09:40 |  10:32| 04:12 | 11:00 |
| Move..|Do a ..|Add .. | Use ..| Change|
| 03:52 |       |       |       |       |

我认为您可以在不使用 numpy 并且仅使用 stdlib 模块的情况下解决此问题！

from itertools import zip_longest

d = {'Fri': ['Commit: 04:15PM Move flex to mixin and do mobile-first queries\n',
         'Commit: 03:52PM use padding to get the margins\n',
         'Commit: 10:09AM Remove field_prepared_logo height\n',
         'Commit: 03:15PM Add the final div to footer\n',
         'Commit: 03:05PM Merge from redesign\n'],
 'Thu': ['Commit: 10:25AM Design qa fixes on /clients page\n'],
 'Tue': ['Commit: 09:40AM remove transform and tweak span placement in '
         'hamburger\n'],
 'Wed': ['Commit: 02:19PM Change blockquote font and width\n']}

for row in zip_longest(d['Tue'], d['Wed'], d['Thu'], d['Fri']):
    print(row)
# ('Commit: 09:40AM remove transform and tweak span placement in hamburger\n', 'Commit: 02:19PM Change blockquote font and width\n', 'Commit: 10:25AM Design qa fixes on /clients page\n', 'Commit: 04:15PM Move flex to mixin and do mobile-first queries\n')
# (None, None, None, 'Commit: 03:52PM use padding to get the margins\n')
# (None, None, None, 'Commit: 10:09AM Remove field_prepared_logo height\n')
# (None, None, None, 'Commit: 03:15PM Add the final div to footer\n')
# (None, None, None, 'Commit: 03:05PM Merge from redesign\n')

zip_longest obviates the need to "even out" your arrays...它只是返回 None 那里没有什么可以放的。您也可以通过fillvalue='' 或类似的方式设置默认值。

您还可以使用有序字典来避免像我一样手动指定日期的顺序。

现在您已经有了单独的行，剩下的就是漂亮打印的练习了。 textwrap module 可能是你的朋友。

编辑：这需要做一些工作，但这里也处理了漂亮的打印

maxwidth = (80//len(d)) - 1  # set this to whatever value you want
wrapper = textwrap.TextWrapper(width=maxwidth, subsequent_indent=' ')

wrapped_commits = {k: [wrapper.wrap(commit) for commit in v] for k, v in d.items()}
justified_commits = {k: [line.ljust(maxwidth) for commit in v for line in commit] for k, v in wrapped_commits.items()}

for l in zip_longest(justified_commits['Tue'], justified_commits['Wed'], justified_commits['Thu'], justified_commits['Fri'], fillvalue=' '*maxwidth):
    print(' '.join(l))

输出如下：
