基本上，我想将这个数据框分成8个单位...所以对于第一个单元，单元1，我想要12列......运行1到12.依此类推。第8单元将以85-96运行。
我刚刚重命名了8个数据框，并指定了我想从主数据框中获取的列（df）
这是我的代码：
df1 = df.ix[:,0:7]
df2 = df.ix[:,12:24]
df3 = df.ix[:,24:36]
df4 = df.ix[:,36:48]
df5 = df.ix[:,48:60]
df6 = df.ix[:,60:72]
df7 = df.ix[:,72:84]
df8 = df.ix[:,84:96]
pieces = (df1,df2,df3,df4,df5,df6,df7,df8)
最后，我使用concat将8个数据帧连接在一起（堆叠在一起）。但是，它的输出有点失真而且不按顺序排列。
df_final = pd.concat(pieces, ignore_index = True)
print df_final
out：

这是我的问题。我希望数据帧排成一行并堆叠在一起。
答案 0 :(得分：1)
你几乎就在那里。
问题是每个子数据帧中的列名都是不同的。因此，当pandas执行concat时，它并不只是将数据框附加到底部，它会将数据框扩展为具有正确名称的新列，然后附加行。
您可以通过重命名子数据帧中的列来解决此问题，例如
for sub_df in pieces:
sub_df.columns=range(12)
N.B。 df2至df8包含您想要的内容。出于某种原因，您已经df1只包含前7列，而不是12列。我现在假设这是一个错字。
导致完整的工作代码（我将输入数据复制到名为'data1.csv'的文件中）
import pandas as pd
import numpy as np
df = pd.read_csv('data1.csv')
df1 = df.ix[:,0:12]
df2 = df.ix[:,12:24]
df3 = df.ix[:,24:36]
df4 = df.ix[:,36:48]
df5 = df.ix[:,48:60]
df6 = df.ix[:,60:72]
df7 = df.ix[:,72:84]
df8 = df.ix[:,84:96]
pieces = (df1,df2,df3,df4,df5,df6,df7,df8)
# Give the columns the same labels in each sub dataframe
# I've used numbers for convenience - you can give more descriptive names if you want
for sub_df in pieces:
sub_df.columns=range(12)
df_final = pd.concat(pieces, ignore_index = True)
print df_final
您注意到示例中列的意外排序。这不会影响我的解决方案，但我会解释它的完整性。
输出中的列位于所谓的'Lexicographic ordering'中。在Python（和其他语言）中对包含数字的字符串进行排序时，这是一个常见问题。它们按照几乎正确的顺序排序，但不知何故运行1,10,11 ...... 19,2,20等等。这是因为排序按字母逐字排序，但0之前9到a
