Do you mean "how do I open a .txt file in an editor from Python"? Try this 
(on Windows):

thePath = r"c:\temp\toto.txt"
# Import a tool module from the library
import os
# Run a system command from Python
# %s is replace by the file path
os.system("notepad %s" % thePath)

Or do you mean "how do I read the content of a .txt file from Python"? In 
this case, try this:

thePath = r"c:\temp\toto.txt"
# Get a file object in read mode
fileObj = open(thePath, 'r')
# Read lines from the text file
lineList = fileObj.readlines()
# Print them out one by one
for aLine in lineList:
    print aLine

If I misunderstood your question, please give us more details.


Cheers.
