Hi, I'm new to Python and am very impressed with it. Unfortunately I am not yet at the stage where I can convert the GFA Basic code below into Python. Can anyone help please? Any response appreciated and will certainly help me to understand more about Python. BTW This is not a challenge to Python, it's more like a challenge from a pal to me.
Thanks Ed -------------------------- GFA Basic Code ---------------------------------- I made a speed test with the following program. It writes all 8 million combinations of 6 of 45 into a field R() and gives each combination a line number, starting from 1 to 8145060 and then it prints the last line to show that all lines are filled. Option Base 1 means, that the first index starts with 1 and not with 0. Print "starting time "; Print Time$ Global a As Int = 0 Global b As Int = 0 Global c As Int = 0 Global d As Int = 0 Global e As Int = 0 Global f As Int = 0 Local i As Int = 0 Dim R(8145060, 7) As Int Option Base 1 For a = 1 To 40 For b = a + 1 To 41 For c = b + 1 To 42 For d = c + 1 To 43 For e = d + 1 To 44 For f = e + 1 To 45 i = i + 1 R(i, 1) = a R(i, 2) = b R(i, 3) = c R(i, 4) = d R(i, 5) = e R(i, 6) = f R(i, 7) = i Next f Next e Next d Next c Next b Next a Print "finished time "; Print Time$ Print "i =" ; i Print R(i, 7), R(i, 1); R(i, 2); R(i, 3); R(i, 4); R(i, 5); R(i, 6) The result of this code: starting time : 10:06:30 finished time: 10:06:41 i = 8145060 8145060 40 41 42 43 44 45 -------------------------- GFA Basic Code ---------------------------------- Within 11 seconds all 8145060 combinations of 6 of 45 have been written into a table together with a line identification number at position R(i,7) , at a 800 MHz computer with 195 MB memory. _______________________________________________ ActivePython mailing list [EMAIL PROTECTED] To unsubscribe: http://listserv.ActiveState.com/mailman/mysubs
