python数据分析饼图，箱线图

通过读取数据covid_19_data.csv的，统计确诊、死亡、治愈人数，并绘制成饼图

covid_19_data.csv

 

 

我的答案：

import matplotlib.pyplot as plt

import numpy as np

import pandas as pd

plt.rcParams['font.family'] = ['sans-serif']

plt.rcParams['font.sans-serif'] = ['SimHei']

date=pd.read_csv("D:\\Project\\covid_19_data.csv",usecols=(5,6,7),)

val=date.values[0:,0]

val2=date.values[0:,1]

val3=date.values[0:,2]

add=0

add1=0

add2=0

for i in range(0,156292):

    add+=val[i]

    add1+=val2[i]

    add2+=val3[i]

fraces=[add,add1,add2]

label=["确诊","死亡","治愈"]

plt.pie(x=fraces,labels=label,autopct="%.0f%%",shadow=True)

plt.show()

成绩.xlsx

 我的答案：

import matplotlib.pyplot as plt

import numpy as np

import pandas as pd

plt.rcParams['font.family'] = ['sans-serif']

plt.rcParams['font.sans-serif'] = ['SimHei']

date=pd.read_excel("D:\\Project\\成绩.xlsx",usecols=("语文","英语","数学","计算机"))

faces=[date["语文"],date["英语"],date["数学"],date["计算机"]]

lable=["语文","英语","数学","计算机"]

plt.boxplot(x=faces,labels=lable)

plt.show()
