有没有办法在除块之外打印自然错误消息？

Question

我正在练习错误处理，我有一个问题。您可以做到吗

try:
    a = int(input('Please enter the first number it must be >= 200' + '\n' + '(note the sum of both numbers must be <=300)'))
    b= int(input('please your second number it must be <= 50'))
    c = a + b
    assert a >=200 and isinstance(a, int), 'invalid entry for a must be <= 200 and a number'
    assert b<=50 and isinstance(b, int), 'invalid entry for b must be <=50 and a number'
    assert c <= 300, 'The sum of your numbers is >300'
except ValueError
    print('error')
else:
    print('All in range')

添加一个除外的，该 sossertionError 并打印出来：

except AssertionError as e:
    print(e.args[0] if e.args else "error")
