在 Python 中将数值变量转换为分类变量

import seaborn as sns
import pandas as pd
import numpy as np
pd.set_option('display.max_rows', 500)
pd.set_option('display.max_columns', 500)
pd.set_option('display.width', 1000)df=pd.read_csv("titanic.csv")
# You also get the same dataset from seaborn
#df=sns.load_dataset('titanic').head(10)df.head()

df['New_Age']=pd.cut(df['Age'],[0,10,18,25,40,90])

df.pivot_table("Survived", index=["Sex","Pclass"],columns="new_age")
