如何在python中暂停循环打印

Question

我有以下代码：

i = 0
numbers = []

while i < 6:
    print ("At the top i is %d" % i)
    numbers.append(i)

    i = i + 1
    print ("Numbers now: ", numbers)
    print ("At the bottom i is %d" % i)


print ("The numbers: ")

for num in numbers:
    print (num)

如果导入sleep它将使速度变慢，但是如何暂停它，以便在需要时继续进行呢？

Answer 1

只需在要暂停的位置添加input()即可。

i=0
numbers = []
while i < 6:
    print("At the top i is %d" % i)
    numbers.append(i)

    i = i + 1
    print("Numbers now: ", numbers)
    print("At the bottom i is %d" % i)
    input() # add it here for example.


print("The numbers: ")

for num in numbers:
    print(num)
