第二次作业(pandas练习)

import pandas as pd t=pd.DataFrame(pd.read_excel('C:\\Users\\ASUS\\Desktop\\lw\\python高级设计test\\数据文件\\titanic.xlsx')) s=t['survived'].value_counts() print('存活人数为{}\n死亡人数为{}'.format(s[0],s[1]))

s=t['sex'].value_counts() print('male人数为{}\nfemale人数为{}'.format(s[0],s[1]))

 

a = 0 b = 0 for i in t.index:     if t['alive'][i] == 'yes':         if t['sex'][i] == 'male':             a += 1         elif t['sex'][i] == 'female':             b += 1 print("男的获救人数为{}\n女的获救人数为{}".format(a, b))

　　

print(t['class'].value_counts())

t = pd.DataFrame(pd.read_excel(file_path)) a = t[['survived', 'pclass']] print(a.corr())

print(t.boxplot(['fare'], ['pclass']))

从图中可看出，船舱等级为1时票价范围较大，船舱等级为2，3时票价范围相对最小
