python6-少有人走的道儿

python

你应该知道这样一首很著名的诗，《少有人走的道儿》。^[1]

那么问题就来了——怎样选那条“少有人走的道儿”呢？

if， elif， else 三剑客荣耀出场！^[2]

让我们来举个栗子：

# choice_question.py
grade = 0

q1 = "The capital of China is ___."
a11 = '1.Beijing'
a12 = '2.Shanghai'
a13 = '3.Nanjing'

q2 = "Python is a(an) ___."
a21 = '1.animal'
a22 = '2.program language'
a23 = '3.both 1 and 2'

print(q1)
print(a11, a12, a13)

get_answer1 = input()

if get_answer1 == '1':
   grade += 2
elif get_answer1 == '2':
   grade += -2
elif get_answer1 == '3':
   grade += -2
else:
   grade += 0

print(q2)
print(a21, a22, a23)

get_answer2 = input()

if get_answer2 == '1':
   grade += 1
elif get_answer2 == '2':
   grade += 1
elif get_answer2 == '3':
   grade += 2
else:
   grade += 0

print("So your final grade is %d." % grade)

我想你应该能无压力看懂这段代码。不过有几个注意事项：
