这里我的while循环出了什么问题？循环一次
这里我的while循环出了什么问题？循环一次
提问于 2015-04-10 12:36:00
我尝试让它循环，直到用户输入一个有效的数字
def daysoftheweek():
print("1-Sunday")
print("2-Monday")
print("3-Tuesday")
print("4-Wednesday")
print("5-Thursday")
print("6-Friday")
print("7-Saturday")
daysoftheweek()
def whatistoday():
day = input("Please enter the number day it is:")
return day
day2 = whatistoday()
def todayis(day2):
day2 = whatistoday()
while True:
if day2 < 1 or day2 > 7:
print ("Please enter a valid input")
return day2
elif day2 == 1:
print("So today is Sunday")
break
elif day2 == 2:
print("So today is Monday")
break
elif day2 == 3:
print("So today is Tuesday")
break
elif day2 == 4:
print("So today is Wednesday")
break
elif day2 == 5:
print("So today is Thursday")
break
elif day2 == 6:
print("So today is Friday")
break
elif day2 == 7:
print("So today is Saturday")
break

试试这个：
def daysoftheweek():
print("1-Sunday")
print("2-Monday")
print("3-Tuesday")
print("4-Wednesday")
print("5-Thursday")
print("6-Friday")
print("7-Saturday")
daysoftheweek()
def whatistoday():
day = input("Please enter the number day it is:")
return day
day2 = whatistoday()
def todayis(day2):
while True:
if day2 == "1":
print("So today is Sunday")
break
elif day2 == "2":
print("So today is Monday")
break
elif day2 == "3":
print("So today is Tuesday")
break
elif day2 == 4:
print("So today is Wednesday")
break
elif day2 == "5":
print("So today is Thursday")
break
elif day2 == "6":
print("So today is Friday")
break
elif day2 == "7":
print("So today is Saturday")
break
else:
day2 = whatistoday()

print("6-Friday")
print("7-Saturday")
daysoftheweek()
def whatistoday():
day = input("Please enter the number day it is:")
return day
day2 = whatistoday()
def todayis(day2):
while True:
if day2 < 1 or day2 > 7:
print ("Please enter a valid input")
day2 = whatistoday()
elif day2 == 1:
print("So today is Sunday")
break
elif day2 == 2:
print("So today is Monday")
break
elif day2 == 3:
