Kau*_*ury 5 python arrays sorting bubble-sort
我bubbleSort function在 python 中有这个可以完美运行。
def bubbleSort(arr):
n = len(arr)
# Traverse through all array elements
for i in range(n):
# Last i elements are already in place
for j in range(0, n-i-1):
# traverse the array from 0 to n-i-1
# Swap if the element found is greater
# than the next element
if arr[j] > arr[j+1] :
arr[j], arr[j+1] = arr[j+1], arr[j]

我是 python 新手,无法理解 if 语句下面的代码。怎样arr[j], arr[j+1] = arr[j], arr[j+1]运作?
