Question

考虑以下数据框：

{('CA', 'ca'): {('A', 'a'): 2,
 ('A', 'aa'): 2,
  ('B', 'b'): 2,
  ('B', 'bb'): 2,
  ('C', 'c'): 2,
  ('C', 'cc'): 2},
 ('CA', 'cb'): {('A', 'a'): 1,
  ('A', 'aa'): 1,
  ('B', 'b'): 1,
  ('B', 'bb'): 1,
  ('C', 'c'): 1,
  ('C', 'cc'): 1}}

如何将数据框转换为可通过复制和粘贴类似于此布局的方法插入布局字符串中？

+-------------+----------+---------+
| First       |   Second |   Third |
+=============+==========+=========+
| ('A', 'a')  |        2 |       1 |

tabulate可能会让您入门：

import pandas as pd
from tabulate import tabulate

df = pd.DataFrame(
    {
        ("CA", "ca"): {
            ("A", "a"): 2,
            ("A", "aa"): 2,
            ("B", "b"): 2,
            ("B", "bb"): 2,
            ("C", "c"): 2,
            ("C", "cc"): 2,
        },
        ("CA", "cb"): {
            ("A", "a"): 1,
            ("A", "aa"): 1,
            ("B", "b"): 1,
            ("B", "bb"): 1,
            ("C", "c"): 1,
            ("C", "cc"): 1,
        },
    }
)

tab = tabulate(df, tablefmt="grid")
print(tab)

输出

+-------------+---+---+
| ('A', 'a')  | 2 | 1 |
+-------------+---+---+
| ('A', 'aa') | 2 | 1 |
+-------------+---+---+
| ('B', 'b')  | 2 | 1 |
+-------------+---+---+
| ('B', 'bb') | 2 | 1 |
+-------------+---+---+
| ('C', 'c')  | 2 | 1 |
+-------------+---+---+
| ('C', 'cc') | 2 | 1 |
+-------------+---+---+

您还可以添加headers：

headers = ["First", "Second", "Third"]
tab = tabulate(df, headers=headers, tablefmt="grid")

然后会生成

+-------------+----------+---------+
| First       |   Second |   Third |
+=============+==========+=========+
| ('A', 'a')  |        2 |       1 |
+-------------+----------+---------+
