读取内置iris数据集：
import seaborn as sns
df = sns.load_dataset('iris')
df.head()
保存文件为csv格式文本，并读入python：
import pandas as pd
## save data
save = pd.DataFrame(df, columns = ['sepal_length', 'sepal_width', 'petal_length', 'petal_width','species'])
save.to_csv('G:/python/iris2.csv', index = False)
## read data
df = pd.read_csv('G:/python/iris2.csv')
print(df)
df.png
绘制简易小提琴图/箱式图：
## plot
import matplotlib.pyplot as plt
polt1 = sns.violinplot(data=df) ## violin
# plot2 = sns.boxplot(data=df) ## box plot
plt.show()
