Question

我正在检查以确保动物园可以让船只与动物一起旅行，为了做到这一点，由于安全原因，离动物园最近的人必须至少在60米以外。我使用下面的代码

#Ask them how far away the closest person is from the ship 
while True:
    try:
        Distance = int(input("How far away is the closest person 
from the ship? (in meters) "))
    except ValueError:
        print("Please enter a number")
        continue
    else:
        break
if Distance <=60:
    print("Please ask them to move away")
else:
    print("People are at a safe distance")

我想这样做，以便问题重新询问他们何时放入太低的距离，然后他们可以再次检查并放入新的距离我希望它看起来像：

How far away is the closest person from the ship (in meters)? 8
Please ask them to move away
How far away is the closest person from the ship (in meters)? 789
People are at a safe distance

Answer 1

将ask()变为函数。从无限循环中调用它。如果break是＆gt;，则循环仅ask()（停止调用Distance） 60。

def ask():
  while True:
    try:
        Distance = int(input("How far away is the closest person from the ship? (in meters) "))
    except ValueError:
        print("Please enter a number")
        continue
    else:
        break
  return Distance

while True:
  if ask() <=60:
      print("Please ask them to move away")
  else:
      print("People are at a safe distance")
      break

如何在第一次输入错误数据时重新询问用户输入
