Question

值包括height = 10，number = 2和bounciness = 6应该达到25.6英尺，但我得到23.2英尺。有人可以帮我理解我的逻辑搞砸了吗？

import math

# User inputs are set up

height = int(input("Enter the height of the ball: "))
number = int(input("Enter the number of bounces of the ball: "))
bounciness = int(input("Enter the height for each successive bounce: "))

count = 0

# Calculation

for count in range(bounciness):
    count = (height * bounciness)/100
    distance = height + count
    bounceSum = number * bounciness
    total = count + distance + bounceSum

# Results

print("The ball has traveled a total distance of", total, "feet.")

Answer 1

如果你看看for循环中的计算，这就是第一次迭代中发生的事情（以及之后的迭代）： -

count = 10 * 6/100 = 0.6
distance = 10 + 0.6 = 10.6（由于上面的行，此处计数为0.6）
bounceSum = 2 * 12 = 12
total = 0.6 + 10.6 + 12 = 23.2

代码中的逻辑问题是变量count。它有3种不同的定义，它们会覆盖另一种：

在之上
count = 0
count，范围从0到bounciness-1

count =（身高* bounciness）/ 100

Answer 2

我想我修好了......

import math

# User inputs are set up

height = int(input("Hello, please enter the height of the ball: "))
number = int(input("Next, enter the number of bounces of the ball: "))
bounciness = int(input("Now enter the height for each successive bounce: "))

index = 0

# Calculation

for index in range(bounciness):
    index = bounciness * 0.6
    distance = height + (bounciness * number)
    total = index + distance

# Results

print("The ball has traveled a total distance of", total, "feet.")

print("Good bye")

Python逻辑不能产生正确的答案，而且我在开发上下文时遇到困难
