我有什么办法可以找到每年国家所获得的最大奖牌数

Question

数据集看起来像这样-

Athlete Country Year    Sport   Gold    Silver  Bronze  Total
0   Yang Yilin  China   2008    Gymnastics  1   0   2   3
1   Leisel Jones    Australia   2000    Swimming    0   2   0   2
2   Go Gi-Hyeon South Korea 2002    Short-Track Speed Skating   1   1   0   2
3   Chen Ruolin China   2008    Diving  2   0   0   2
4   Katie Ledecky   United States   2012    Swimming    1   0   0   1
5   Ruta Meilutyte  Lithuania   2012    Swimming    1   0   0   1
6   Dániel Gyurta   Hungary 2004    Swimming    0   1   0   1
7   Arianna Fontana Italy   2006    Short-Track Speed Skating   0   0   1   1
8   Olga Glatskikh  Russia  2004    Rhythmic Gymnastics 1   0   0   1
9   Kharikleia Pantazi  Greece  2000    Rhythmic Gymnastics 0   0   1   1
10  Kim Martin  Sweden  2002    Ice Hockey  0   0   1   1
11  Kyla Ross   United States   2012    Gymnastics  1   0   0   1
12  Gabriela Dragoi Romania 2008    Gymnastics  0   0   1   1
13  Tasha Schwikert-Warren  United States   2000    Gymnastics  0   0   1   1
14  Yang Yun    China   2000    Gymnastics  0   0   1   1

这就是我现在正在做的事情，如何只打印国家，年份和总奖牌（每年最多）

gk=df1.groupby('Year')

for Year,Year_df in gk:
    print(Year)
    print(Year_df.groupby('Country')['Total'].sum())
