取两个整数输入，即x = 10和y = 50，并以10,20 20,30,30,40和40,50的格式打印

Question

x = int(input("Enter the start Number:"))
y = int(input("Enter the end number:"))

while(start < end):

    start = start + 10
    new = start + 10
    print start, new

请有人帮助我。 我希望输出像

10,20
20,30
30,40
40,50

Answer 1

你想要这样的东西吗？

start = int(input("Enter the start Number:"))
end = int(input("Enter the end number:"))

while(start < end):
    print start, start + 10
    start = start + 10

Answer 2

如果你已经知道要循环多少次，那么使用for循环和range要简洁得多：

start = int(input("Enter the start Number:"))
end = int(input("Enter the end number:"))

for n in range(start, end, 10):
    print(n, n + 10)
