使用 If 和 Elif 修复

Question

代码：

import random

print('hello, pls give me ur wish and me will tell how many % it will happen.')
wish = input()

percentage = random.randint(1, 100)
print('ok, ' + wish + ', let us see.....')

print(percentage,"% that you is")

if (percentage <= 75) :
  boop = "wow is very high for happen"
elif (percentage <= 50) :
  boop = "hmmm, is will happen maybe"
elif (percentage <= 25) :
  boop = "low chance of happen, is will might no happen"
elif (percentage <= 1) :
  boop = "very low, wish u lucc"
elif (percentage == 0) :
  boop = "too bad so sad, is no happen"
print(boop)

我尝试了运行代码，它可以工作，但结果不是我所期望的：

I want to fly.
ok, I want to fly., let us see.....
28 % that you is
wow is very high for happen
>>>

百分比是 28%，应该是 "low chance of happen, is will might no happen" 但相反，它显示 "wow is very high for happen"。如果有人可以帮助我，请帮助我。

Answer 1

您需要为 if (percentage <= 75) 和其他人添加一个 >= 条件，例如 >= 50。现在，对于任何小于 75 的值，它 returns 为真。或者，您可以翻转它，使 (percentage == 0) 位于第一个，if (percentage <= 75) 位于最后一个。

Answer 2

将 < 符号替换为 > 符号。

原因： 28 小于 75 所以 percentage <= 75 为真，得到 wow is very high for happen。它应该是 percentage >= 75 所以当你在 elif (percentage >= 25) : 中看到条件 percentage >= 25 时，你将得到正确的输出 low chance of happen, is will might no happen

percentage = 28
if (percentage >= 75) :
  boop = "wow is very high for happen"
elif (percentage >= 50) :
  boop = "hmmm, is will happen maybe"
elif (percentage >= 25) :
  boop = "low chance of happen, is will might no happen"
elif (percentage >= 1) :
  boop = "very low, wish u lucc"
elif (percentage == 0) :
  boop = "too bad so sad, is no happen"

Answer 3

很少有错误，例如：

您没有 else 情况，因此如果百分比大于或等于 75，则会出现错误。
您是从较高的点开始比较的，即百分比 <75，这将始终为真。

import random
percentage = random.randint(1, 100)

print(percentage,"% that you is")
if (percentage == 0) :
    boop = "too bad so sad, is no happen"
elif (percentage <= 1) :
    boop = "very low, wish u lucc"
elif (percentage <= 25) :
    boop = "low chance of happen, is will might no happen"
elif (percentage <= 50) :
    boop = "hmmm, is will happen maybe"
elif (percentage <= 75) :
    boop = "wow is very high for happen"
else:
    boop="above 75"
print(boop)```

Answer 4

将 if、elif 语句中的 <= 替换为 >=。这样，按照你的陈述的顺序，它会比较列表中的向下，它总是属于正确的类别。
