This might help you ... [code]# test data (tab separated) data_test = """\ Tree Branches Leaves Height Cedar 12 80 100 Pine 9 70 80 Maple 15 100 120 """ fname = "file.txt" # write the test file fout = open(fname, "w") fout.write(data_test) fout.close() # read the test file back …

Just a thought, I have used that trick before. You can use [CODE]canvas.move(canvas_object, xAmount, yAmount) root.update()[/CODE]to move the object you created right off the canvas to hide it. Then bring it or another object back.

Great find!

Well, you are close. A test print line will help ... [code]def sums(n): sum = 0 for i in range(0, n + 1, 1): sum = sum + i print i, sum # test return sum def main(): n = input('Enter a number: ') s = sums(n) print 'The sum …

You don't want to change the dictionary you are iterating over.

There really isn't a need for module datetime in your example ... [code]import time # create yyyymmdd string # uses today's time tuple by default today = time.strftime("%Y%m%d") print today # eg. 20100329 [/code]

If I understand this right, you could also use this approach ... [code]# name, score text for the test test_text = """\ John, 88 Mark, 75 Frank, 79 Bob, 56""" fname = "myscores.txt" #write the multiline text to a test file fout = open(fname, "w") fout.write(test_text) fout.close() # read the …

[B]file.writelines(str(new) + " passes" + "\n")[/B] expects a list as argument, use [B]file.write(str(new) + " passes" + "\n")[/B] to write a string Also, [B]file[/B] is a function name in Python2, it would be better to use something like variable name [B]fapp[/B] (for file append)

To write out to file use ... [code] fileHandle = open ( 'scores.txt', 'w' ) fileHandle.write(str1) fileHandle.close() [/code]To append to an existig file use ... [code] fileHandle = open ( 'scores.txt', 'a' ) fileHandle.write(str1) fileHandle.close() [/code]
