我正在尝试编写一个程序，该程序将允许用户输入20个随机数字，这些数字将被添加到一个空列表中。一旦收集了20个数字，它将打印数字的最低，最高和总和。我在第5行的user_numbers.append（num_entry）上不断收到语法错误，但我无法弄清楚自己在做什么错。有人可以在这里指出正确的方向吗？

user_numbers = []

while len(user_numbers) <= 20:
    num_entry = int(input('Please enter any number.
')
    user_numbers.append(num_entry)

    if len(user_numbers) == 20:

        low_num = min(user_numbers)
        high_num = max(user_numbers)
        sum_num = sum(user_numbers)

        print('The lowest number in the list is:', low_num, '.')
        print('The highest number in the list is:', high_num, '.')
        print('The sum of the numbers in the list is:', sum_num, '.')

答案

python
$ python foo.py
  File "foo.py", line 5
    user_numbers.append(num_entry)
               ^

在行尾缺少) ... num_entry = int(input('Please enter any number. ')
