我想将文件夹中的一组 yaml 文件转换为 xlsx 文件。我想我会先尝试将一个 yaml 文件转换为一个 xlsx 文件。文件夹中的yaml文件格式如下：

info:
    city: Bangalore
    competition: IPL
    dates:
       - 2008-04-18
    gender: male
    match_type: T20
    outcome:
           by:
              runs: 140
           winner: Kolkata Knight Riders
    overs: 20
    player_of_match:
        - BB McCullum
    teams:
        - Royal Challengers Bangalore
        - Kolkata Knight Riders
    toss:
        decision: field
    winner: Royal Challengers Bangalore
    umpires:
        - Asad Rauf
        - RE Koertzen
    venue: M Chinnaswamy Stadium
    innings:
        - 1st innings:
        team: Kolkata Knight Riders
        deliveries:
                     - 0.1:
                           batsman: SC Ganguly
                           bowler: P Kumar
                           extras:
                                  legbyes: 1
                           non_striker: BB McCullum
                           runs:
                                batsman: 0
                                extras: 1
                           total: 1

比赛的每个球（0.2、0.3、0.4 ... 20.0）的数据继续，并转移到比赛的下半场（第二局）并继续进一步

我尝试将这些 yaml 文件之一转换为 xlsx 文件：

import pandas as pd
import yaml as ya
with open(r"location of folder") as f:
    
    data = ya.load(f, Loader=ya.FullLoader)
    df1=pd.DataFrame(data['info'])
    df1.to_excel(r"location of folder\output.xlsx")

但是，运行上面的代码后，我得到了以下错误：

File "c:\Users\kosal\hello\prj.py", line 8, in <module>
    df1=pd.DataFrame(data['info'])
  File "C:\Users\kosal\anaconda3\lib\site-packages\pandas\core\frame.py", line 529, in __init__
    mgr = init_dict(data, index, columns, dtype=dtype)
  File "C:\Users\kosal\anaconda3\lib\site-packages\pandas\core\internals\construction.py", line 287, in init_dict
    return arrays_to_mgr(arrays, data_names, index, columns, dtype=dtype)
  File "C:\Users\kosal\anaconda3\lib\site-packages\pandas\core\internals\construction.py", line 80, in arrays_to_mgr
    index = extract_index(arrays)
  File "C:\Users\kosal\anaconda3\lib\site-packages\pandas\core\internals\construction.py", line 401, in extract_index
    raise ValueError("arrays must all be same length")

我确实知道为什么会出现这个错误，但我不知道应该如何修复它。

附：我找不到适合这个问题的标签，因此使用了“python”标签。

【解决方案1】：

你遇到过yaml格式的困惑，首先你应该检查你的yaml格式，注意每个缩进

您的情况下的 Yaml 格式示例

info:
  city: Bangalore
  competition: IPL
  dates:
    - 2008-04-18
  gender: male
  match_type: T20
  outcome:
    by:
      runs: 140
      winner: Kolkata Knight Riders
  overs: 20
  player_of_match:
    - BB McCullum
  teams:
    - Royal Challengers Bangalore
    - Kolkata Knight Riders
  toss:
    decision: field
  winner: Royal Challengers Bangalore
  umpires:
    - Asad Rauf
    - RE Koertzen
  venue: M Chinnaswamy Stadium
  innings:
    - 1st_innings:
      team: Kolkata Knight Riders
      deliveries:
        - 0.1:
          batsman: SC Ganguly
          bowler: P Kumar
          extras:
            legbyes: 1
          non_striker: BB McCullum
          runs:
            batsman: 0
            extras: 1
          total: 1

然后你检查你的

pip install pyyaml
pip install pandas
pip install openpyxl

import pandas as pd
import yaml as ya
with open(r"location of folder") as f:
    
    data = ya.load(f, Loader=ya.FullLoader)
    df1=pd.DataFrame(data['info'])
    df1.to_excel(r"location of folder\output.xlsx")
