How to prompt the user for a directory location?

[Miguel Valenzue]

Hi, I currently am running a simple script that substitutes the comma in a text file with a period. This is basically to change a bunch of european files to american dot.
I'd like to prompt the user and allow the user to browse for a location of the folder when the program is run.
This is my current code.

path="C:\Python27\RED"
#I need to make path browseable
import os
myFiles=os.listdir(path)

def replaceText(myFile):
    for line in open(myFile):
        line = line.replace(",", ".")
        o.write(line)
    

for x in myFiles[:]:
    myFile = x
    writeFile = "period" + x
    o = open(writeFile,"a")
    replaceText(myFile)   
    o.close()

How does one do this in Python?

You can call raw_input() for the user to enter a string, or you can create a Tkinter widget such as tkFileDialog.as kopenfilename(). Other GUI toolkits have comparable widgets.
