这个if语句和打印的问题在哪里？
这个if语句和打印的问题在哪里？
提问于 2020-10-03 16:23:56
我正在努力理解我正在做的这个测试练习。我编写了下面的代码并执行它，但是结果并不是我真正想要的。第一个if语句应该打印日期或天数，具体取决于所传递的天数。最后的打印，解决方案，应该打印的日子加上文字之间的空格，然而，我不能做到这一点。提前感谢！
well_height = 125
daily_distance = 30
nightly_distance = 20
snail_position = 0
notEscaped = True
# Create a variable days to keep
# count of the days that pass until the snail escapes the well
days = 0
fullDaylydist = daily_distance - nightly_distance
while snail_position < well_height:
if days <= 1:
print(str(days) + " day gone")
else:
print(str(days) + " days gone")
snail_position += fullDaylydist
if snail_position < well_height:
days += 1
# Print the solution.
else:
print(str(days) + " days and I am out from the well!")回答 2

这里的诀窍是蜗牛白天向前移动，晚上向后移动。蜗牛在睡觉前一天会到达顶端。
well_height = 125
daily_distance = 30
nightly_distance = 20
snail_position = 0
notEscaped = True
days = 1
snail_position = 0
fullDaylydist = daily_distance - nightly_distance # assumes full day
while snail_position < well_height - daily_distance: # check if snail reaches top during day
if days <= 1:
print(str(days) + " day gone")
else:
print(str(days) + " days gone")
snail_position += fullDaylydist
if snail_position < well_height:
days += 1
# Loop done, Print the solution.
print(str(days) + " days and I am out from the well!") # last day输出
1 day gone
2 days gone
3 days gone
4 days gone
5 days gone
6 days gone
7 days gone
8 days gone
9 days gone
10 days gone
11 days and I am out from the well!Stack Overflow用户

第一个if小于或等于一天。您的意思是这个，还是应该说大于或等于>=
