python - 在 Python 中将包含元组列表的字典转换为 DataFrame

Question

我正在尝试将带有元组列表作为值的 2 键字典转换为 pandas DataFrame。我正在使用的数据如下所示:

dictionary={'Week':[(week1,week2),(week3,week4)],'Numbers':[(number1,number2),(number3,number4)]}

是否有办法将其转换为如下所示的 pandas DataFrame:

Week   Numbers
week1  number1
week2  number2
week3  number3
week4  number4

我尝试使用pandas.DataFrame(dictionary)将字典强制转换为DataFrame，但最终得到一行有两个非常宽的列。任何指导将不胜感激!

Answer 1

您可以使用itertools.chain.from_iterable展平每个键的元组并调用数据帧构造函数:

import itertools
df = pd.DataFrame({k: [*itertools.chain.from_iterable(v)] for k,v in dictionary.items()})

    Week  Numbers
0  week1  number1
1  week2  number2
2  week3  number3
3  week4  number4
