Code that i have tried till now
import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
df= pd.DataFrame()
for f in ['E:\\olympics\\Olympics-2002.xlsx','E:\\olympics\\Olympics-
2006.xlsx','E:\\olympics\\Olympics-2010.xlsx',
'E:\\olympics\\Olympics-2014.xlsx','E:\\olympics\\Olympics-
2018.xlsx']:
data = pd.read_excel(f,'Sheet1')
df = df.append(data)
df.to_excel("E:\\olympics\\combineddata.xlsx")
data = pd.read_excel("E:\\olympics\\combineddata.xlsx")
print(data)
final_Data={}
for i in data['Country']:
x=i
t1=(data[(data.Country==x)].Total).tolist()
print("Name of Country=",i, int(sum(t1)))
final_Data.update({i:int(sum(t1))})
t3=data.groupby('Country').Total.sum()
t2= df['Total'].sum()
t4= t3/t2*100
print(t3)
print(t2)
print(t4)
this how is got the answer....Now i need to pull that in plot i want to put it pie
Let's assume you have created the DataFrame as 'df'. Then you can do the following to first group by and then calculate percentages.
df = df.groupby('Country').sum()
df['Gold_percent'] = (df['Gold'] / df['Gold'].sum()) * 100
df['Silver_percent'] = (df['Silver'] / df['Silver'].sum()) * 100
df['Bronze_percent'] = (df['Bronze'] / df['Bronze'].sum()) * 100
df['Total_percent'] = (df['Total'] / df['Total'].sum()) * 100
df.round(2)
print (df)
The output will be as follows:
Gold Silver Bronze ... Silver_percent Bronze_percent Total_percent
Country ...
Australia 5 1 1 ... 1.14 1.49 3.02
China 9 8 13 ... 9.09 19.40 12.93
Germany 33 41 21 ... 46.59 31.34 40.95
UK 2 1 1 ... 1.14 1.49 1.72
USA 28 37 31 ... 42.05 46.27 41.38
