使用While循环语句进行输入验证

Question

我在检查用户输入时遇到问题。如果它不在特定范围内，则它将再次提示用户并澄清参数范围。 我很好奇下面的代码为什么不起作用。

current_speed = int(input("What is the current speed (in mph 51 - 60)? "))

while 51 > current_speed > 60:
    current_speed = int(input("Please enter a speed between (51 - 60 mph): "))

应该提升用户重新输入速度，直到它达到指定的条件。在此示例中，用户需要输入51和60 mph之间的速度，然后才能脱离while循环。

Answer 1

您没有正确检查数字。

current_speed = int(input("What is the current speed (in mph 51 - 60)? "))

while 51 > current_speed or current_speed > 60: 
    current_speed = int(input("Please enter a speed between (51 - 60 mph): "))

Answer 2

尝试以下代码：

printSection

Answer 3

具有在括号中编写条件并分别检查多个条件的习惯。

current_speed = int(input("What is the current speed (in mph 51 - 60)? "))

while (current_speed < 51 or current_speed > 60):
    current_speed = int(input("Please enter a speed between (51 - 60 mph): "))
