我正在处理足球数据集,这是我遇到的错误。请帮忙,
#what is the win rate of HomeTeam?
n_matches = df.shape[0]
n_features = df.shape[1] -1
n_homewin = len(df(df.FTR == 'H'))
win_rate = (float(n_homewin) / (n_matches)) * 100
print ("Total number of matches,{}".format(n_matches))
print ("Number of features,{}".format(n_features))
print ("Number of maches won by hom team,{}".format (n_homewin))
print ("win rate of home team,{:.2f}%" .format(win_rate))
