即使已经解释了,我在这里也不十分了解该标志的用法。我正在独自研究通用算法,下面是执行冒泡排序(摘自stackabuse)的信息:
我将其修改为:
def bubble_sort(nums):
# We set swapped to True so the loop looks runs at least once
for p in range(len(nums)):
for i in range(len(nums) - 1):
if nums[i] > nums[i + 1]:
# Swap the elements
nums[i], nums[i + 1] = nums[i + 1], nums[i]
# Set the flag to True so we'll loop again
random_list_of_nums = [5, 2, 1, 8, 4]
bubble_sort(random_list_of_nums)
print(random_list_of_nums)
def bubble_sort(nums):
# We set swapped to True so the loop looks runs at least once
swapped = True
while swapped:
swapped = False
for i in range(len(nums) - 1):
if nums[i] > nums[i + 1]:
# Swap the elements
nums[i], nums[i + 1] = nums[i + 1], nums[i]
# Set the flag to True so we'll loop again
swapped = True
random_list_of_nums = [5, 2, 1, 8, 4]
bubble_sort(random_list_of_nums)
print(random_list_of_nums)
应该在内部循环,但不是
