python 3类型错误：'&燃气轮机'；在'；int'；和'；str'；在if状态下

这是我正在做的GCSE生物测验。

如果它变成负数，我想把分数设为0

据我所见，变量

int\u score

表明它包含一个整数，在if语句中，您可以编写：

Q_1 = input ('Name the organelles where protiens are synthesised? : ')
if Q_1 == 'ribosome':
    print ('correct')
    score = score + 1
else:
    print ('WRONG')

Q_2 = input ('Suggest why plant cells have a cell wall and animal cells don\'t ?: ')
if Q_2 == 'To control the flow of water and oxygen':
    print ('correct')
    score = score + 1

else:
    print ('WRONG')
    score = score -1

Q_3 = input ('True or false is bacteria an examples of a prokaryotic cell ?: ')
if Q_3 == 'true':
    print ('correct')
    score = score + 1

else:
    print ('WRONG')
    score = score -1

Q_4 = input ('True or false prokaryotes don\'t have a cell wall ?: ')
if Q_4 == 'true':
    print ('correct')
    score = score + 1

else:
    print ('WRONG')
    score = score -1

Q_5= input ('What is a stem cell?: ')
if Q_5 == 'An undifined cell':
    print ('correct')
    score = score + 1

else:
    print ('WRONG')
    score = score -1

Q_6 = input ('True or false there are embryonic stem cells?: ')
if Q_6 == 'true':
    print ('correct')
    score = score + 1

else:
    print ('WRONG')
    score = score -1

Q_7 = input ('What is diffusion?: ')
if Q_7 == 'The movment of gas particles from an area of high concentraction to low concentration':
    print ('correct')
    score = score + 1

else:
    print ('WRONG')
    score = score -1

Q_8 = input ('True or false having a greater surface area increase the rate of diffusion?: ')
if Q_8 == 'true':
    print ('correct')
    score = score + 1

else:
    print ('WRONG')
    score = score -1

Q_9 = input ('Define osmosis ?: ')
if Q_9 == 'The movment of water particles from an area of high to low concentration':
    print ('correct')
    score = score + 1

else:
    print ('WRONG')
    score = score -1


Q_10 = input ('True or false increasing temperature increases the rate of osmosis?: ')

if Q_10 == 'true':
    print ('correct')
    score = score + 1

else:
    print ('WRONG')
    score = score -1
int_score = int(score)

if int_score >'0':
    score = 0
    print (score)

作为旁注，我建议您检查正确答案的算法不是最优的，因为您必须输入准确的答案才能获得正确答案。您可能需要检查以下关键字：

假设答案是光合作用产生葡萄糖和氧气，检查“葡萄糖”和“氧气”：

if int_score < 0:
