[Tutor] Filtering text files

[David Talaga]

Filtering text filesOh yea, including this, the other problem I am having is
when I run it the statement after the if statements is aid to be illegal
syntax!?!?!?!
The revised code is as follows:
import os
import Tkinter
root=Tkinter.Tk()
var=Tkinter.StringVar()
entry=Tkinter.Entry(root, textvariable=var)
entry.focus_set()
entry.pack()
var.set(root.title())
def changeTitle(): root.title(var.get())
def changeDriveC(): os.chdir('C:\\')
def changeDriveD(): os.chdir('D:\\')
def changeDriveE(): os.chdir('E:\\')
def changeDriveF(): os.chdir('F:\\')
def changeDriveG(): os.chdir('G:\\')
Tkinter.Button(root, text="Change Title", command=changeTitle).pack()
Tkinter.Button(root, text="Iconify", command=root.iconify).pack()
Tkinter.Button(root, text="Close", command=root.destroy).pack()
C=Tkinter.Radiobutton(text="Change dir to C:", value=0).pack()
D=Tkinter.Radiobutton(text="Change dir to D:", value=0).pack()
E=Tkinter.Radiobutton(text="Change dir to E:", value=0).pack()
F=Tkinter.Radiobutton(text="Change dir to F:", value=0).pack()
G=Tkinter.Radiobutton(text="Change dir to G:", value=0).pack()
if C.select():
    C=Tkinter.Radiobutton(text="Change dir to C:",
value=1,command=os.chdir('C:\\').pack()
elif D.select():
    D=Tkinter.Radiobutton(text="Change dir to D:",
value=1,command=os.chdir('D:\\').pack()
elif E.select():
    E=Tkinter.Radiobutton(text="Change dir to D:",
value=1,command=os.chdir('E:\\').pack()
elif F.select():
    F=Tkinter.Radiobutton(text="Change dir to D:",
value=1,command=os.chdir('F:\\').pack()
elif G.select():
    G=Tkinter.Radiobutton(text="Change dir to D:",
value=1,command=os.chdir('G:\\').pack()

Tkinter.mainloop

  Can I get some help here!! <just kidding> Ok, here's the deal, I am using
tkinter and trying to figure out how to un select the radio button at
startup.  here is my code in it's entirety.

  import os
  import Tkinter
  root=Tkinter.Tk()
  var=Tkinter.StringVar()
  entry=Tkinter.Entry(root, textvariable=var)
  entry.focus_set()
  entry.pack()
  var.set(root.title())
  def changeTitle(): root.title(var.get())
  def changeDriveC(): os.chdir('C:\\')
  def changeDriveD(): os.chdir('D:\\')
  def changeDriveE(): os.chdir('E:\\')
  def changeDriveF(): os.chdir('F:\\')
  def changeDriveG(): os.chdir('G:\\')
  Tkinter.Button(root, text="Change Title", command=changeTitle).pack()
  Tkinter.Button(root, text="Iconify", command=root.iconify).pack()
  Tkinter.Button(root, text="Close", command=root.destroy).pack()
  C=Tkinter.Radiobutton(text="Change dir to C:", value=0).pack()
  D=Tkinter.Radiobutton(text="Change dir to D:", value=0).pack()
  E=Tkinter.Radiobutton(text="Change dir to E:", value=0).pack()
  F=Tkinter.Radiobutton(text="Change dir to F:", value=0).pack()
  G=Tkinter.Radiobutton(text="Change dir to G:", value=0).pack()
  if C.select():
      C=Tkinter.Radiobutton(text="Change dir to C:",
value=1,command=os.chdir('C:\\').pack()

  Tkinter.mainloop


  The if statement was a test that went wrong.  Anyone? Anyone?

    Hello,

       I posted several question about filtering text files. I am still a
little confused. I ran through some of the tutorials on python.org and I am
still getting hung up. I am running python 2.3.3. When I try and run the
program below I receive the prompt on the shell and no new file is created
in my directory. Here is the code from
http://www.ibiblio.org/obp/thinkCSpy/chap11.htm. I have in my directory a
file named lmps for the input file. Also do the names in the function have
to be the same as the names of the files being loaded? I have tried both.
Thanks

    Ara

    def filterFile(lmps, newFile):
      f1 = open(lmps, "r")
      f2 = open(newFile, "w")
      while 1:
        text = f1.readline()
        if text == "":
          break
        if text[0] == 'I':
          continue
        f2.write(text)
      f1.close()
      f2.close()
      return
