Question

使用while循环无法获得正确的计数值

尝试使用全局变量，但无法理解其用法甚至语法

尝试使用变量外部的计数

print('I am thinking of a number between 1 and 20')
selectedNumber=12
while True:
    user_number=int(input("Please enter your number?\n"))
    if user_number<selectedNumber:
        print('Your guess is too low')
        global count=count+1
    elif user_number==selectedNumber:
        break
    else:
        print('Your guess is too high')
print('Great Job', count)

我建议在循环外部定义count变量，然后在每次循环运行时（而不是在条件内部）递增该变量；也许像这样：

print('I am thinking of a number between 1 and 20')
selected_number = 12
count = 0

while True:
    user_number = int(input("Please enter your number: "))
    count += 1

    if user_number < selected_number:
        print('Your guess is too low')
    elif user_number == selectedNumber:
        break
    else:
        print('Your guess is too high')

print('Great Job', count)
