The presense of a delimiter indicates that there is a field both before and after the delimiter. If it didn't work that way, then you'd get the same results for input = "2b 3 4bx 5b 2c 4a 5a 6" as you would for input = "b 3 4bx 5b 2c 4a 5a 6" you would get the same results for input = "2222b22222" as you would for intput = "b" > What can I do so that the first element is not an empty > string? but the 'b34bx5b' string as I expected? projectOptions = (input.replace(" ", "")).split('2') if projectOptions[0] == '': del projectOptions[0] print projectOptions -- Grant Edwards grante Yow!
