編輯Python文件庫和packges用VB.NET

Question

我有一些Python文件，我想改變自己的頭：

import os 
import math 

我需要像導入之前添加目錄：

from com.firebox import os 
from com.fireboxtraining import math 

（我有導演列表）

我知道如何閱讀流讀者。有人在這裏幫助瞭如何獲得清單。但是現在我想粘貼目錄或包。那麼該怎麼辦？

Answer 1

Python文件只是普通文件，你可以像閱讀任何文本文件一樣閱讀。 您需要做的是打開文件，檢查包含導入的行，更改這些行，然後將所有行寫入新文件。
爲了讓您一開始，這裏是與被冷落爲你找出份樣機：

Dim file As System.IO.File 
Dim reader as System.IO.StreamReader 
Dim line As String 
reader = file.OpenText("ThePythonFile.py") 

'open a new file for writing the results here 

While reader.Peek <> -1 
    'get lines one by one 
    line = reader.ReadLine() 

    'check to see if it has import. this is just an example, 
    'you should have a more complicated check here, like regex 
    If line.Contains("import") Then 
     'alter the line as you wish 
    End If 

    'Write the line to the new file 

End While 
reader.Close() 

'close the second file 
'If you want, you can replace the old file with the new one here
