df_small = df.iloc[:,:6] correlation_mat = df_small.corr() sns.heatmap(correlation_mat, annot = True) plt.show() Output: The plot shows a 6 x 6 matrix and color-fills each cell based on the correlation coefficient of the pair representing it. ...
这个iloc 解决方案正是我所寻找的。删除前 x 列变成 `df = df.iloc[:, x:]` 如果你想删除 x 到 y 列,你可以这样做: `all_cols = set(range(0,len(df.columns)) ) keep_cols = all_cols - set(范围(x,y+1)) df = df.iloc[:, list(keep_cols)]` (2认同) 这个答案值得更多的赞成,...
