从以元组为键的字典中获取 pandas 数据框 [英] Obtaining a pandas dataframe from a dict with tuples as keys

问题描述

我是python的新手，已经为这个问题苦苦挣扎了一段时间了.我有一个像这样的字典:

I am new to python and have been struggling with this problem for quite a while. I have a dict like this:

dict1 = {(a,a) : 5, (a,b) :10, (a,c) : 11, (b,a): 4, (b,b) : 8, (b,c) : 3....}

我想做的是将其转换为如下所示的熊猫数据框:

What I would like to do is convert this into a pandas dataframe that looks like this:

    a    b    c
a   5    10   11
b   4    8    3
c   ..   ..   ..

之后，我想在jupyter笔记本中创建一个多条形图.我知道您可以将数据显示为熊猫系列，以显示以下内容:

After that I would like to create a multiple bar plot in the jupyter notebook. I know you can display the data as a pandas series to show the following:

dataset = pd.Series(dict1)
print dataset
    a  a  5
       b  10
       c  11
    b  a  4
       b  8
       c  3
    c  a  ..
       b  ..
       c  ..

但是，我无法由此创建多条图.

However, I was not able to create a multiple bar plot from that.
