I am trying to open Notepad using popen and write something into it. I can't get my head around it. I can open Notepad using command:
notepadprocess=subprocess.Popen('notepad.exe')
I am trying to identify how can I write anything in the text file using python. Any help is appreciated.
You can at first write something into txt file (ex. foo.txt) and then open it with notepad:
import os
f = open('foo.txt','w')
f.write('Hello world!')
f.close()
os.system("notepad.exe foo.txt")
Hello world! text in it. What do you see?You may be confusing the concept of (text) file with the processes that manipulate them.
Notepad is a program, of which you can create a process. A file, on the other hand, is just a structure on your hard drive.
From a programming standpoint, Notepad doesn't edit files. It:
Your program, just as any other program, can manipulate files, just as notepad does. In particular, you can perform exactly the same sequence as Notepad:
my_file= "myfile.txt" #the name/path of the file
with open(file, "rb") as f: #open the file for reading
content= f.read() #read the file into memory
content+= "mytext" #change the memory
with open(file, "wb") as f: #open the file for writing
f.write( content ) #write the memory into the file
Found the exact solution from Alex K's comment. I used pywinauto to perform this task.
