Python代码不会添加到变量中

Question

我已经为一个项目的一个非常基本的测验编写了一些代码，但无论我做什么，程序总是输出我在开始时设置变量的内容。 它似乎是选择正确的输入，而else语句是有效的，所以我只能假设我在添加到“per”时做错了但是我无法弄清楚这是什么代码......

from random import randint
print(" How like solly are you? Take a test!")
print(" whats your name?")
appendMe = str(input())
input(" press enter to start")
global per
def T(per , a , b , qu):
   per = (per + 0 )
   print(" Input the letter of the answer you choose !")
   print ( qu )
   print ( a )
   print ( b )
   choice = str(input())
   if choice == "A" :
       per = int(per + 10)
   elif choice == "B" :
       per = int(per)
   else:
       print(" Input either A , B , C or D ... Lets try again...")
       Q(per , a , b ,c ,d)



def Q(per , a , b ,c ,d):
       per = (per + 0 )
       cho = int(randint(0,2))
       if cho == 1 :
        print(" Input the letter of the answer you choose !")
        print ( qu )
        print ( a )
        print ( b )
        print ( c )
        print ( d )
        choice = str(input())
        if choice == "A" :
            per = int(per + 5)
        elif choice == "B" :
            per = int(per + 2)
        elif choice == "C" :
             per = int(per)
        elif choice == "D" :
                    per = int(per )
        else:
             print(" Input either A , B , C or D ... Lets try again...")
             Q(per , a , b ,c ,d)
    else:
        print(" Input the letter of the answer you choose !")
        print ( qu )

        print ( a )
        choice = str(input())
        if choice == "D" :
            per = int(per + 5)
        elif choice == "C" :
            per = int(per + 2)
        elif choice == "B" :
            per = int(per )
        elif choice == "A" :
            per = int(per)
        else:
            print(" Input either A , B , C or D ... Lets try again...")
            Q(per , a , b ,c ,d)

Answer 1

您的问题是您误用了global声明。 它应该在一个函数内部，所以你的函数变成了

def T(a , b , qu):
    global per
    per = (per + 0 )
    etc...

def Q(a , b ,c ,d):
   global per
   per = (per + 0 )
   etc...

编辑：您现在不再需要将per作为参数传递给函数，因此您还应该从函数调用中删除它。

Answer 2

你应该编写一个函数，它返回点的变化，而不是真正尝试改变点。

from random import shuffle

def ask(question, answers):
    print("Input the letter of the answer you choose !")
    random.shuffle(answers)
    all_points = {}
    for letter, (answer, points) in zip("ABCDEFG", answers):
        print("{}: {}".format(letter, answer)
        all_points[letter] = points
    while True:
        choice = input()
        if choice in all_points:
            break
        print("Input either A , B , C or D ... Lets try again...")
    return all_points[choice]

per = 50 
per += ask("What is/was/will be your favourite subject at school", [
    (" Computer science ", 5),
    (" English", 2),
    (" art", 0),
    (" textiles", 0)])
per += ask(" What are your beliefs on body and soul?", [
    (" I'm pretty sure the soul dosen't exist...", 5),
    (" Whats a soul?", 2),
    (" I agree with plato , The soul exist and its one with the body", 0),
    (" I agree WTH", 0)])
