pandas 合并单元格、拆分单元格

遍历行 iterrows for i,r in df_train.iterrows(): print(r['company']) itertuples（速度快） for r in df_train.itertuples(): print(getattr(r, "company")) break 遍历列 iteritems for i, r in df_train.iteritems(): print(i, r)

python seaborn画热力图，自定义颜色渐变 默认的颜色，，实在是有点不好看 所以先附上改了以后的效果图 方法是使用 LinearSegmentedColormap 自定义颜色渐变 from matplotlib.colors import LinearSegmentedColormap my_colormap = LinearSegmentedColormap.from_list("", ["white", "blue"]) ax = sns.heatmap(data,cmap=my_colo
