my_list = ["TITLE","COMPANY","TENURE",
"Board Member","Softbank Corp","06/2007–06/2015",

我有上面的列表，我想将其转换为 3xN 格式（3 列，N 行）

预期输出：

TITLE           COMPANY        TENURE
Board Member  Softbank Corp  06/2007–06/2015
Chairman     Alibaba.Com Ltd 10/2007–PRESENT

你试过用熊猫吗？

pandas.pydata.org

【参考方案1】：

你可以使用 pandas 数据框：

可以使用单个列表或列表列表创建 DataFrame。

import pandas as pd

my_list = ["TITLE","COMPANY","TENURE",
"Board Member","Softbank Corp","06/2007–06/2015",
 "Chairman","Alibaba.Com Ltd","10/2007–PRESENT",
"Board Member","Huayi Brothers","FORMER"]

# Convert flat list into nested list with 3 items
data_ = [my_list[i:i + 3] for i in range(0,len(my_list),3)] 

#Create a DataFrame from Lists 
print (pd.DataFrame(data_[1:],columns=data_[0:1][0]))

输出：

          TITLE          COMPANY           TENURE
0  Board Member    Softbank Corp  06/2007–06/2015
1      Chairman  Alibaba.Com Ltd  10/2007–PRESENT
2  Board Member   Huayi Brothers           FORMER
