python Tabulate library: TypeError: zip_longest argument #1 must support iteration

Question

我有这本字典：{'id': 1, 'inner': {'test1': 1, 'test2': 2}} ，我想将其制成表格，但出现以下异常：

>>> from tabulate import tabulate
>>> d = {'id': 1, 'inner': {'test1': 1, 'test2': 2}}
>>> tabulate(d)

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File ".../env/lib/python3.6/site-packages/tabulate.py", line 1529, in tabulate
    tabular_data, headers, showindex=showindex
  File ".../env/lib/python3.6/site-packages/tabulate.py", line 1089, in _normalize_tabular_data
    izip_longest(*tabular_data.values())
TypeError: zip_longest argument #1 must support iteration

我不明白为什么我会遇到这种情况，以及如何确保这种情况不会再次发生。我的字典是我的服务器答案，它的模式可以很容易地改变，这种格式应该支持一切（！），所以我正在寻找一个通用的解决方案。我知道并非每个模式都可以格式化为 table，但这是用户的选择。

Answer 1

根据文档：

The following tabular data types are supported:

  1.list of lists or another iterable of iterables
  2.list or another iterable of dicts (keys as columns)
  3.dict of iterables (keys as columns)
  4.two-dimensional NumPy array
  5.NumPy record arrays (names as columns)
  6.pandas.DataFrame

如果你想使用字典，它必须是 dict of iterable，这意味着你的例子是

{'id': [1], 'inner': {'test1': [1], 'test2': [2]}}
