为什么无论我的分数是多少，我都会收到相同的输出?

Question

我正在做这个"测验"，我正在尝试像评分系统一样添加

#starting score
score = 0
if Question_1 in ("Cheetah", "CHEETAH", "cheetah"):
score =+ 1
else:
pass
if Question_2 in ("Sailfish", "SAILFISH", "sailfish"):
score =+ 1
else:
pass
if Question_3 in ("Peregrine Falcon", "peregrine falcon", "PEREGRINE FALCON", "pf"):
score =+ 1
else:
pass
if Question_4 in ("A decade", "Decade", "DECADE", "decade"):
score =+ 1
else:
pass

if Question_5 in ("Centimetre", "Centimetres", "CENTIMETRE", "CM", "cm", "centi", "centimetre"):
score =+ 1
else:
pass

#once all answers have been checked display result
if score == 0:
print("your result was 0/5, very bad!")
elif score == 1:
print("your result was 1/5, bad!")
elif score == 2:
print("your result was 2/5, mid!")
elif score == 3:
print("your result was 3/5, good!")
elif score == 4:
print("your result was 4/5, very good!!")
elif score == 5:
print("your result was 5/5, EXCELLENT!!")
else:
pass

当我测试我的代码时，如果我的分数是 0，它会输出为 0，但如果我的分数是 1、2、3、4 或 5，它会输出，就好像我只回答了一个正确的问题一样，有人知道为什么吗？ 我也想知道是否有任何其他方法可以做分数系统，例如使用"while循环"？

Answer 1

您需要的运算符是+=。=+只是一个带有有符号正整数的=。

Answer 2

将score =+ 1更改为score += 1。+=和-=用于递增和递减。=+和=-用于有符号整数。

>>> score = 0
>>> score += 1
>>> score
1

>>> score = -1
>>> score =+ 1
>>> score
1

为什么需要通过其他？当您想要跳过循环中的进一步执行时，将使用 pass。在您的代码片段中，我认为 pass 没有任何意义。

如果If-Else语句不在循环中，则可以删除传递。如果使用If，则不强制要求Else。

score = 0
if Question_1 in ("Cheetah", "CHEETAH", "cheetah"):
score =+ 1
if Question_2 in ("Sailfish", "SAILFISH", "sailfish"):
score =+ 1

if Question_3 in ("Peregrine Falcon", "peregrine falcon", "PEREGRINE FALCON", "pf"):
score =+ 1
if Question_4 in ("A decade", "Decade", "DECADE", "decade"):
score =+ 1
if Question_5 in ("Centimetre", "Centimetres", "CENTIMETRE", "CM", "cm", "centi", "centimetre"):
score =+ 1
