为什么会出现“ IndexError：列表索引超出范围”错误？

Question

I am trying to create a bubble sort in python, but I keep getting the error code: "IndexError: list index out of range". I am not sure where I am going wrong, as I don't know where my code exceeds its bounds:

def swaps():
    while dataset[i] > dataset[i+1]:
        temp = dataset[i]
        dataset[i] = dataset[i+1]
        dataset[i+1] = temp
        print (dataset)

dataset = ["6", "3", "5", "2", "4", "1"]
newset = ["0", "0", "0", "0", "0", "0"]

for i in range(0,6):
    newset[i] = swaps()

Any help or advice would be greatly appreciated! x

Answer 1

range(0, 6) = [0, 1, 2, 3, 4, 5] . When it gets to 5 . then 5 + 1 = 6 . and you don't have an item at dataset[6] .

And as Zach King has pointed out - it's not good practice to use global variables in this case, passing objects through as arguments to a function would be a lot nicer.
