Question

#Quiz answer variables go here!
ca1 = cringe_crew[0]
ca2 = cucks[0]
ca3 = 5
ca4 = cringe_crew[1]
ca5 = 'No'

#Questions
q1 = "Question 1 - Who do we refer to when shouting CODE YELLOW? "
q2 = "Question 2 - Who would you think of if I called him 'Linux Boy': "
q3 = "Question 3 - How many people were there in the original Cringe-Crew back in the days of 2015? "
q4 = "Question 4 - Biggest pseudo Overwatch fan? (top tip: even bought a bag): "
q5 = "Question 5 - Do we miss Luke Slater? "

#a is the raw_input answer
#b is the correct answer needed
#a1-a5 will be separately stored raw_input ANSWERS
#ca1-ca5 are already called as variables and these are the correct answers.

#Score

score = 0

def compare( a, ca ):
    if a == ca:
        score = score + 1
        print "That's correct! The answer was %s" % ca
        print "Your score is", score

    else:
        print "%s is not the correct answer - you did not get a point!" % a
    return;


#test
a1 = raw_input(q1)
compare( a1, ca1 )
a2 = raw_input(q2)
compare( a2, ca2 )
a3 = raw_input(q3)
compare( a3, ca3 )
a4 = raw_input(q4)
compare( a4, ca4 )
a5 = raw_input(q5)
compare( a5, ca5 )

嘿伙计们，我对python和编码整体都是全新的，但是想通过一个小小的测验来开始，虽然我觉得我在结构方面做了完全错误，如果我删除＆＃ 39;得分＆＃39;代码运行完全正常。如果我拥有它，就会发生这种情况：

Traceback (most recent call last):
  File "ex2.py", line 57, in <module>
    compare( a1, ca1 )
  File "ex2.py", line 46, in compare
    score = score + 1
UnboundLocalError: local variable 'score' referenced before assignment

在这种情况下，您能否给我任何提示，尤其是如何构建代码？非常感谢！

Answer 1

在compare()函数中，在尝试访问score变量之前，您尚未定义def compare( a, ca, scr ): if a == ca: scr = scr + 1 print "That's correct! The answer was %s" % ca print "Your score is", scr else: print "%s is not the correct answer - you did not get a point!" % a return scr ; # skipping some code here score = compare( a1, ca1, score )变量。

你应该将它传递给compare函数（将它作为参数添加到函数中），然后返回结果（首选），或者将其声明为函数中的全局变量（更简单，但技术上不是最好的方法）。

例如

传递参数＆amp;返回值解决方案：

def compare( a, ca ):
    global score
    if a == ca:
        score = score + 1
        print "That's correct! The answer was %s" % ca
        print "Your score is", score

    else:
        print "%s is not the correct answer - you did not get a point!" % a
    return;

全局变量解决方案：

score

否则，全局范围中的score与compare范围内的options:{ scales: { xAxes: [{ stacked:true}] } }完全不同，即使它们具有相同的名称。

Answer 2

在比较功能中，添加得分的全局声明：

Tess.setVariable("user_words_suffix", "user-words");
