For 循环到 运行 直到达到变量值
For loop to run until hitting variable value
我正在尝试 Python 在与我相关的项目的自我思考和利用 teamtreehouse 之间学习,尽管进展缓慢。
我正在尝试查找有关如何制作 python 3.3.2 for 循环 运行 从值 0 到用户输入可变小时的值的教程。到目前为止,我只收到一个错误 运行ning 这段代码。我没有成功找到涵盖这种方法的教程。
下面的教程似乎涵盖了从零开始然后 运行 打印出 lists/dictionariies 的值

与本教程相同

这让我开始思考,如果这不可能,我需要 research/learn 其他循环吗?

不完全确定你正在尝试做什么,但使用 range 并将你的代码保持在一个函数中会更接近:
def user_input():
# keep track of running total
total_distance = 0
# cast hours and mph to int
speed_mph = int(input("Please provide the speed the vehicle was going in MPH."))
hours = int(input("Please provide the number of hours it has been traveling in hours."))
# loop from 1 to hours + 1, ranges are not inclusive
for i in range(1, hours + 1):
distance_traveled = speed_mph * i
total_distance += distance_traveled
print("Travelled {} miles after {} hour/s".format( distance_traveled,i))
print("Total distance travelled {} miles after {} hour/s".format(total_distance,hours))
user_input()
