[英]How to store tuples and continue to ask the user to input more values until user inputs 'done'?
因此,任務是創建一個元組列表,其中存儲了運行日期,運行了多長時間以及在該日期運行了多少英里。 程序應繼續要求用戶輸入有關運行時間的信息,直到用戶輸入“完成”為止。 輸出應該是存儲在名為“ run_data”的列表中的所有元組。 這是我所擁有的:
def data(date, time, distance):
list1 = [(date, time, distance)]
done = False
while input == done:
run_data = list1.append((date, time, distance))
def main():
d = input('input the date of your run in the form mmdd: ')
t = input('input how long your run was in minutes: ')
m = input('input the distance you ran in miles: ')
running = data(d, t, m)
print(running)
main()
輸入時我沒有任何錯誤,但是在詢問距離之后,它什么也沒有輸出。 我很困惑為什么它輸出了那個,並且不確定我哪里出錯了。 我想提一下,我是使用python的初學者,因此將非常感謝您的幫助。 謝謝!
看看這個。 將控件放入main,循環直到“完成”。
def data(date, time, distance):
return (date, time, distance)
def main(tList):
while true:
d = input('input the date of your run in the form mmdd: ')
if d == 'done':
break
t = input('input how long your run was in minutes: ')
m = input('input the distance you ran in miles: ')
tList.append(data(d, t, m))
timeList = []
main(timeList)
print(timeList)
要連續獲取輸入,您可以將main編寫為:
list1 = []
while True:
d = input('input the date of your run in the form mmdd: ')
t = input('input how long your run was in minutes: ')
m = input('input the distance you ran in miles: ')
list1.append((d, t, m))
# YOu can ask the user if you want to add more data.
print "Would you like to add more data"
done = raw_input()
if(done == "yes" or "y"):
continue
else:
break
print list1
這樣,您可以連續將數據添加到列表中,最后打印列表。 編碼愉快!
