import pandas as pd import matplotlib.pyplot as plt
mat_data = pd.read_excel('./football_data.xlsx')
data1=mat_data[mat_data['Country']=='Spain']
data2=data1[data1['Year']==2016]
data3=data1[data1['Year']==2017]
data4=data1[data1['Year']==2018]
data5=data1[data1['Year']==2019]
data6=data1[data1['Year']==2020]
pandas的dataframe支持标签内筛选数据，还是很强的，包装了遍历的方法。
plt.bar(data2['Player Names'], data2['Goals'])
plt.xticks(rotation=270)
如果X轴坐标太挤可以xticks方法旋转270度
plt.title('Player Names-Goals')
plt.xlabel('Player Names')
