                  问题描述

                  我正在尝试找到一种方法来一次附加多个熊猫数据帧,而不是使用一个一个地附加它们

                  I am trying to find some way of appending multiple pandas data frames at once rather than appending them one by one using

                  df.append(df)
                  

                  假设有 5 个 pandas 数据帧 t1t2t3t4t5.我如何一次附加它们?相当于

                  Let us say there are 5 pandas data frames t1, t2, t3, t4, t5. How do I append them at once? Something equivalent of

                  df = rbind(t1,t2,t3,t4,t5)
                  

                  推荐答案

                  您是否尝试过使用列表作为 append 的参数?还是我错过了什么?

                  Have you simply tried using a list as argument of append? Or am I missing anything?

                  import numpy as np
                  import pandas as pd
                  
                  dates = np.asarray(pd.date_range('1/1/2000', periods=8))
                  df1 = pd.DataFrame(np.random.randn(8, 4), index=dates, columns=['A', 'B', 'C', 'D'])
                  df2 = df1.copy()
                  df3 = df1.copy()
                  df = df1.append([df2, df3])
                  
                  print df
