每行要文件包含多个值-python

Question

I'm trying to store scores per user to a file in python and I'm not being able to.

I have two lists, names[] & points[] . Everytime the program runs it appends user and score, but when it's run again, the score in the file gets overwritten rather than added to that user.

def quiz():

names=[]
points=[]
name=input("What is your name?")
for x in range (0,1)
    pnt=0  
    num1=3
    num2=4
    print("Whats", num1, '+', num2)
    answer = num1+num2
 userAns=int(input())
 if userAns==answer:
    print("Excellent")
    pnt = pnt+1
 else:
    print("wrong") 
    print("Well done", name, "you scored", point, "/10")
    points.append(point)
    names.append(name)
    class_name = class_name + ".csv"   
    c=open(class_name , 'a+') ##This part forward it prints to another row rather then appending score in the same row
    mw = csv.writer(c)
    rows = zip(names,points)
    mw.writerows(rows)
    c.close()

I need to print the user and then multiple scores alongside it, any help would be appreciated

Answer 1

Hmm, your code cannot be run, and it does not look like what it does what it should be doing even other than the part about appending values to the same row. I am confused as to what the actual requirements are for what you are trying to do, but to append values to the same row (assuming each user gets his own file):

c=open(class_name , 'a+') 

can be changed to

c=open(class_name , 'rb+')  # csv are considered as binary files
c.seek(-2,2) # go to \r\n
mv.writerows(   #... write now

Alternatively, if all users and scores are in the same file (which seems to be what you want, based on your description), you can simply replace the contents of the current file, so just write to it normally and replace the existing contents
