[Tutor] Newbie question: join() string method

[Moedeloos Overste]

Ha!

Thanx for all the input everybody. I finally got it to work. The contents of 
the list is now stored in the file without the []. The solution is in the 
code below. Next step in my learning process is reading the file contents 
and storing it in a dictionary.

One question: When I run the program from IDLE it writes the data to file 
but when I run it from the command prompt(win32)  it doesn't. why is this?



code:

vDraws = input("How many times do you want to draw the lottery? :>")

# Draw lottery numbers & writing them to file

while vDraws > 0:
    LotNumbers = random.sample(range(1,45), 6) #random numbers from range 
into list)
    strgOutput=",".join(str(i) for i in LotNumbers)   #??????converting list 
to string to store it.
    fout = open("draw__output.dat", "a")
    fout.write(strgOutput + "\n")  #writing string to file
    fout.close()
    vDraws = vDraws - 1
