#從簡明Python搬來
number = 23
# 將23賦值給number的變量
running = True
# 在while語句運行前，將running變量設置為ture


while running:
    # 先檢查變量running是否為ture，然後再運行相應的塊
    guess = int(input(‘Enter an integer : ‘))

    if guess == number:
        print(‘Congratulations, you guessed it.‘)
        # 這將導致 while 循環中止
        running = False
    
 
elif guess < number:
        print(‘No, it is a little higher than that.‘)
    else:
        print(‘No, it is a little lower than that.‘)
else:
    print(‘The while loop is over.‘)
# 在這裏你可以做你想做的任何事
print(‘Done‘)

4、while循環練習
