Question

我需要使用“for”循环来计算用户输入的卡路里。一切都是基于输入，除了卡路里燃烧的速度。（3.4）每分钟。

这是我到目前为止所拥有的。我得到了正确的答案，但它无限地重复循环。

time = int(input('How many minutes were you exercising? '))

for i in range (time):
    calories = (time * 3.4)
    calories = float(calories)
    print(calories)

Answer 1

你不需要循环;你已经做过的繁殖就是所需要的：

time = int(input('How many minutes were you exercising? '))
calories = time * 3.4
print(calories)

我还删除了calories = float(calories)，因为它是多余的（当您将int乘以float时，您会获得float）。

P.S。如果使用for循环是此分配的要求，请考虑将两个数字相乘的含义。

Answer 2

您可以累积每分钟的卡路里数。

time = int(input('How many minutes were you exercising? '))

calories = 0  
for i in range(time):
    calories += 3.4

print('You burned {} calories'.format(calories))

我需要用Python编写一个程序来计算在进行活动时燃烧的卡路里
