问题描述
这是我计划用于创建饼图的代码。
import csv
with open('C:\\Users\Bhuwan Bhatt\Desktop\IP PROJECT\Book1.csv','r') as file :
reader = csv.reader(file)
import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
def piechart1():
df=pd.read_csv('data,csv',sep=' ',index_col=False,skipinitialspace=True\,error_bad_lines=False,encoding= 'unicode_escape')
df=df.set_index(['Country'])
dfl=df.iloc[:,[14]]
final_df=dfl.sort_values(by='TotalMedal')
final_df.reset_index(inplace=True)
final_df.columns=('location','Total cases','Total Deaths')
final_df=final_df.drop(11,axis='index')
countries=df['Country']
tmedals=df['TotalMedal']
plt.pie(tmedals,labels=countries,explode=(0.1,0.2),shadow=True,autopct='%0.1f%%')
plt.title("Olympics data analysis\nTop 10 Countries",color='b',fontsize=12)
plt.gcf().canva.set_window_title("OLMPICS ANALYSIS")
plt.show()
由于某种原因，我收到此错误：
AttributeError: 'DataFrameGroupBy' object has no attribute 'sort_values'
这是我一直在使用的CSV文件：
