我在 python3 中使用 seaborn 可视化了一个数据集，但它给了我一个错误。 / 不支持的操作数类型：'str' 和 'int'

Question

import pandas as pd
from pandas import Series,DataFrame
import numpy as np
import matplotlib.pyplot as plt
import seaborn as sns
sns.set_style('whitegrid')
%matplotlib inline
poll_df=pd.read_csv('http://elections.huffingtonpost.com/pollster/2012-general-election-romney-vs-obama.csv')
#poll_df is the data which i have read from a csv file.
sns.factorplot('Affiliation',data=poll_df)

Answer 1

我很难理解这个问题。列 Affiliation 的值 str 不是 numeric.

如果您想计算每个 str 类别的总数并绘制条形图，请尝试：

import pandas as pd
from pandas import Series,DataFrame
import numpy as np
import matplotlib.pyplot as plt
import seaborn as sns
sns.set_style('whitegrid')
%matplotlib inline
poll_df=pd.read_csv('http://elections.huffingtonpost.com/pollster/2012-general-election-romney-vs-obama.csv')
#poll_df is the data which i have read from a csv file.
sns.countplot('Affiliation',data=poll_df)
