Question

我在一个文件夹中有许多文本文件。每个文本文件都有两个分别写在不同行中的值（在.write函数中使用\ n \）。看起来如下。

0.907831
0.992549

我想创建一个主excel文件，该文件将文本文件中的所有值组合在一起（而不是手动输入）。

所需的输出如下所示。

'Filename' 0.907831 0.992549

到目前为止，我有以下代码。

import xlwt
import os
import fnmatch

path='Z:\Data\13-output'
wbk = xlwt.Workbook()
sheet = wbk.add_sheet('data')
row = 0


for files in os.walk(path):
     for file in files:
         if fnmatch.fnmatch(file, '*.txt'):
             L = open(os.path.join( file), "r").read()
             sheet.write(row,5,L)
             row += 1

wbk.save('all_values_in_txt.xls')

它会生成名为“ all_values_in_txt.xls”的excel文件。但是，excel工作表为空白。关于如何改进/修复代码的任何想法吗？

编辑1（通过将fnmatch更改为fnmatch.fnmatch进行修复）：我意识到我遇到了以下错误，if fnmatch(file, '*.txt'): TypeError: 'module' object is not callable

编辑2：我现在遇到新的错误

  File "<ipython-input-81-ddeb0284f378>", line 17, in <module>
    if fnmatch.fnmatch(file, '*.txt'):

  File "C:\Users\JohnDoe\Anaconda3\lib\fnmatch.py", line 34, in fnmatch
    name = os.path.normcase(name)

  File "C:\Users\JohnDoe\Anaconda3\lib\ntpath.py", line 48, in normcase
    s = os.fspath(s)

TypeError: expected str, bytes or os.PathLike object, not list

仅基于一些非常轻松的测试，看来它应该对您有用。

Sub ReadFilesIntoActiveSheet()

Dim fso As FileSystemObject
Dim folder As folder
Dim file As file
Dim FileText As TextStream
Dim TextLine As String
Dim Items() As String
Dim i As Long
Dim cl As Range

' Get a FileSystem object
Set fso = New FileSystemObject

' get the directory you want
Set folder = fso.GetFolder("C:\your_path_here\")

' set the starting point to write the data to
'Set cl = ActiveSheet.Cells(1, 1)
Dim sht As Worksheet
Dim LastRow As Long

Set sh = ActiveSheet

' Loop thru all files in the folder
For Each file In folder.Files
    ' Write file-name
    LastRow = sh.Cells(sh.Rows.Count, "A").End(xlUp).Row + 1
    Range("A" & LastRow).Select
    ActiveCell = file.Name

    ' open the file
    Set txtFile = fso.OpenTextFile(file)

    col = 2
    Do While Not txtFile.AtEndOfStream
        dat = Application.Transpose(Application.Index(Split(txtFile.ReadLine, ","), 1, 0))
        sh.Cells(LastRow, col).Resize(UBound(dat), 1) = dat
        col = col + 1
    Loop

    ' Clean up
    txtFile.Close
    'Range(cl.Address).Offset(1, 0).Select
Next file

Set FileText = Nothing
Set file = Nothing
Set folder = Nothing
Set fso = Nothing

End Sub

注意，您需要从Excel中的一个模块运行它。
